If It rained for 9.5 hours, how many inches of rain would have fallen?
Answer:
I believe the answer is 6.5 inches of rain
Step-by-step explanation:
6.33 (with 3 repeating forever) OR 6 [tex]\frac{1}{3}[/tex]
If it was 4 inches after 6 hours lets make an equation. h being the number of hours and i being the inches of rain.
[tex]\frac{4}{6}[/tex]xh = i
Now fill it in with what we know
[tex]\frac{4}{6}[/tex]x9.5 = i
Now solve it.
You get:
6.33 (with 3 repeating forever) OR 6 [tex]\frac{1}{3}[/tex]
Two times the reciprocal of a number equals 16 times the reciprocal of 20. Find the number. (1 point)
Let the number be x .
Reciprocal of x :-
[tex] = \frac{1}{x} [/tex]
An equation to find x :-
[tex]2 \times \frac{1}{x} = 16 \times \frac{1}{20} [/tex]
[tex] \frac{2}{x} = \frac{16}{20} [/tex]
[tex]16 \times x = 20 \times 2[/tex]
[tex]16x = 40[/tex]
[tex]x = \frac{16}{40} [/tex]
[tex]x = \frac{4}{10} [/tex]
[tex]x= \frac{4 \div 2}{10 \div 2} [/tex]
[tex]x = \frac{2}{5} [/tex]
Reciprocal of x :-
[tex] = \frac{5}{2} [/tex]
Which means the number :-
[tex] = \frac{5}{2} [/tex]
We can check it by :-
[tex]2 \times \frac{2}{5} = \frac{16}{20} [/tex]
[tex] \frac{4}{5} = \frac{16}{20} [/tex]
[tex] \frac{4}{5} = \frac{16 \div 4}{20 \div 4} [/tex]
[tex] \frac{4}{5} = \frac{4}{5} [/tex]
LHS = RHS
Which means we have found the correct number .
Therefore , the value of the number , whose reciprocal multiplied by 2 gives 16 times the reciprocal of 20 is :-

Answer:
In total, you have $668.00.
To reserve enough for the last day, you need to subtract the last day's budget:
This means that, for the remaining 6 days in the week, you have $583.00.
Assuming an equal amount is being spent each day, you can calculate the daily budget by dividing the remaining total by the number of days left.
To avoid going over budget, you can spend $97.16 per day for the other six days.

Find M<1 in the figure below. PQ and RS are parallel
Answer:
m∠1= 105°
Step-by-step explanation:
The m∠1 and 75° are supplementary angles that sum up to 180°.
The equation here would be: m∠1+75= 180.
Step 1- Subtract 75 to both sides of the equation.
m∠1+75= 180
-75 -75
m∠1= 105
Hope this helps! :)
Answer: The answer would be 105.
Step-by-step explanation:
If you look at the angle's corresponding angle, then you will see that it is right next to angle one. So the angle next to angle one is also 75 degrees because it is the same angle or the corresponding angle to the other one that is 75 degrees. So, together, angle one and the angle next to it should equal 180 degrees. So you subtract 180-75=105. And angle one equals 105.

Charlene and Gary want to make confetti. In order to get the right balance of ingredients for their tastes they bought 3 pounds of paper hearts at $2.46 per pound, 5 pounds of sparkling stars for $3.05 per pound, and 3 pounds of shiny coils for $2.33 per pound. Determine the cost per pound of the coffeti.
Answer:
0.712 cents per pound
Step-by-step explanation:
Since we are given the exact amount of each ingredient as well as the price for that amount then we simply need to calculate how much each pound of the confetti actually costs. We do this by adding together all of the pound of all of the ingredients and then adding together all of the costs. Lastly, we divide the cost by the total amount of pounds to find the cost per pound of the confetti like so...
3lbs. + 5lbs. + 3lbs. = 11 lbs.
$2.46 + $3.05 + $2.33 = $7.84
$7.84 / 11 lbs. = 0.712 cents per pound
Therefore, the cost per pound of the confetti is 0.712 cents per pound

Sharon wants to open a checking account from which to pay bills. She wants online services, and a debit card, which both banks provide for free. Based upon past experience, she expects to accidentally overdraft the account 1 time per year, due to unexpected charges and miscommunications. She expects no 2nd copies of statements, and to use network ATMs 4 times per month with either bank. She has $3300 in an emergency savings account at First State Bank, and thinks that the balance will be enough to cover overdrafts in the future if automatic transfers are made when needed.
Answer:
a.No, Common Bank will save Sharon more money.
Step-by-step explanation:
There are two banks i.e. first state bank and the common bank that should be compared in the table depend upon the prices of both the banks
On seeing it we get to know that the first state bank would charged a fee on a monthly basis i.e. $4 while on the other hand the common bank has no fee on the monthly basis
Also the unsufficient bonds are more cheaper in the common bank if we compared with the first state bank
Moreover, the $7 is charged in the first state bank and $3 charged in the common bank.
Therefore the common bank would become cheaper
Hence, the correct option is a.

Tom drove 504 miles in 8 hours. At the same rate, how many miles would he drive in 12 hours
Answer:
756 miles in 12 hours
Step-by-step explanation:
504÷8=63
63 miles per hour
63×12=756
9514 1404 393
Answer:
756
Step-by-step explanation:
If you recognize that 12 (=8 +8/2) is half-again as much as 8, then you would know that Tom would drive half-again as much as 504 miles. That is, he would drive 504 +504/2 = 504+252 = 756 miles in 12 hours.
__
Since the rate is constant, you can write a proportion:
d/12 = 504/8 = distance/time
d = (12/8)(504) 1.5×504 = 756
Tom would drive 756 miles in 12 hours at that rate.
The recipe for 1 pie calls for 2 cups of flour. Which statement is true?

B. O 8 cups of flour are needed for 4 pies.
C.
1 cup of flour are needed for 2 pies.
D.

cups of flour are needed for 8 pies.
Hi!
Lets use a ratio. the recipe calls for 2 cups, for every pie, which is one pie.
So the ratio is 2:1
Now, lets look at the possible answers.
A, has the ratio 12:6. We need to use the ratio 2:1 to make sure this is correct. 2 x 6 = 12, and 12 ÷ 6 = 2, so A is a possibility.
B, has the ratio 8:4. Again, we check with the first ratio 2:1. 2 x 8 = 16, and 16 ÷ 4 = 4, so because the first equation did NOT equal 4, B is not a possibility.
C, has the ratio of 1:2. Because its TWO cups for ONE pie, it wouldn't be correct, so C is not a possibility as well.
D, has the ratio of 9:8. Again, we need to check if its correct using the original ratio of 2:1. 2 x 9 = 18, and 18 ÷ 2 = 2. The ratios do not match, therefore D is not a possibility at all as well.
So, Your Answer Is: A, 12 cups of flour are needed for 6 pies. Also know as the ratio, 12:6
(Here's a tip. When using ratios, use the original ratio to help you out. If when you multiply it doesn't equal the 2nd ratio (as in, 0:6 ⇇⇇ that one right there), and then you divide and it equals the first ratio (as in, this one right here ⇉⇉0:6), it still incorrect.... if all of that made sense)

Answer:
B. Weight
Price
The price per pound of walnuts is the slope or unit rates of the graphs, lines and equations
The greatest price per pound of walnuts is $14.00
(a) Cost of 1.5 bags is $12.99
The unit rate is calculated as:
[tex]\mathbf{Rate = \frac{Cost}{Bags}}[/tex]
So, we have:
[tex]\mathbf{Rate = \frac{\$12.99}{1.5}}[/tex]
[tex]\mathbf{Rate = \$8.66}[/tex]
The price per pound of walnuts is $8.66
(b) The table
From the table, we have the following points
[tex]\mathbf{(x,y) =(0.2,2.80)\ (0.4, 5.60)}[/tex]
The unit rate is calculated as:
[tex]\mathbf{Rate = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{Rate = \frac{5.60 - 2.80}{0.4 - 0.2}}[/tex]
[tex]\mathbf{Rate = 14}[/tex]
The price per pound of walnuts is $14.00
(c) The graph
From the table, we have the following points
[tex]\mathbf{(x,y) =(0,0)\ (1, 11)}[/tex]
The unit rate is calculated as:
[tex]\mathbf{Rate = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{Rate = \frac{11 - 0}{1 - 0}}[/tex]
[tex]\mathbf{Rate = 11}[/tex]
The price per pound of walnuts is $11.00
By comparison, the greatest price per pound of walnuts is $14.00

If SSR=30 and SSE=20, determine SST, then compute the coefficient of determination, r2, and interpret its meaning. SST=nothing r2=nothing (Type an integer or a decimal. Do not round.) Interpret the meaning of r2. Choose the correct answer below. A. It means that 1−r2 of the variation in the dependent variable cannot be explained by the variation in the independent variable. B. It means that r2•100% of the variation in the dependent variable can be explained by the variation in the independent variable. C. It means that 1−r2•100% of the variation in the independent variable cannot be explained by the variation in the dependent variable. D. It means that r2 of the variation in the independent variable can be explained by the variation in the dependent variable.
Answer:
R² value implies that 60% of the variation in the dependent variable can be explained by the variation in the independent variable.
Step-by-step explanation:
The information provided is:
SSR = 30
SSE = 20
Compute the total sum of squares as follows:
SST = SSR + SSE
= 30 + 20
= 50
The coefficient of determination R² specifies the percentage of the variance in the dependent-variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).
The coefficient of determination R² can be computed as follows:
[tex]R^{2}=\frac{SSR}{SST}[/tex]
[tex]=\frac{30}{50}\\\\=0.60[/tex]
The coefficient of determination value is 0.60 or 60%.
This value implies that 60% of the variation in the dependent variable can be explained by the variation in the independent variable.

Of 1000 randomly selected cases of lung cancer, 838 resulted in death within 10 years. Construct a 95% two-sided confidence interval on the death rate from lung cancer. (a) Construct a 95% two-sided confidence interval on the death rate from lung cancer. Round your answers to 3 decimal places. (b) Using the point estimate of p obtained from the preliminary sample, what sample size is needed to be 95% confident that the error in estimating the true value of p is less than 0.03
Answer:
0.8152 ≤ p ≤ 0.8608
579
Step-by-step explanation:
Given the following :
Samples size n = 1000
Deaths within 10 years, p = 838
α = 95%
Construction a two way confidence interval:
p ± Zα/2 * √p(1-p) / n
point estimate p = 838/n = 838/1000 = 0.838
Z0.05/2 = Z0.025 = 1.96
0.838 - 1.96√0.838(1-0.838) / 1000
0.838 - 1.96*0.0116514 = 0.8152
0.838 + 1.96√0.838(1-0.838) / 1000
0.838 + 1.96*0.0116514 = 0.8608
0.8152 ≤ p ≤ 0.8608
b) Using the point estimate of p obtained from the preliminary sample, what sample size is needed to be 95% confident that the error in estimating the true value of p is less than 0.03
Error (E) = 0.03
To find the samome size, use the relation:
n = (Zα/2 / E)² * p(1-p)
n = (1.96/0.03)² * 0.838(1-0.838)
n = (1.96/0.03)² * 0.838 * 0.162
n = 4268.4444 * 0.838 * 0.162
n = 579.46
n = 579
