A hot air ballon travels 18 miles in 3 hours. At this rate how many miles will the hot air ballon travel in a half hour
Answer:
3
Step-by-step explanation:
[tex]\frac{18m}{3hr} = \frac{Xm}{0.5hr}\\cross muultiply\\3Xmhr = 18(0.5)mhr\\3X = 18(0.5)\\3X = 9\\X = \frac{9}{3}\\X = 3[/tex]

In a sample of 63 cans, the average diameter was found to be 3.7in. with a standard deviation of 0.32. Give a point estimate for the population variance of the diameter of the cans
Answer:
0.32
Step-by-step explanation:
Given that:
The sample size of the population = 63
The sample mean = 3.7
The sample standard deviation = 0.32
Thus, the point estimate for the population variance of the diameter of the cans is said to be the standard deviation of the population = 0.32
Suppose the variance (S²) is given as 0.32
Then the standard deviation will be [tex]\sqrt{S^2}[/tex]
=[tex]\sqrt{0.32}[/tex]
= 0.57
Then, since the sample standard deviation is the point estimate, we would have had 0.57 as the answer.

How do you do this question?
Answer:
R = 1
I = [-1, 1)
Step-by-step explanation:
Use the ratio test:
lim(n→∞)│aₙ₊₁ / aₙ│
lim(n→∞)│[xⁿ⁺¹ / (8(n+1) − 1)] / [xⁿ / (8n − 1)]│
lim(n→∞)│[xⁿ⁺¹ / (8n + 7)] × [(8n − 1) / xⁿ]│
lim(n→∞)│[x (8n − 1) / (8n + 7)]│
lim(n→∞)│[(8n − 1) / (8n + 7)]││x│
│x│
The series converges if the limit is less than 1.
│x│< 1
So the radius of convergence is 1.
Solving for x:
-1 < x < 1
Check the endpoints.
If x = -1, the series is ∑ (-1)ⁿ / (8n − 1), which converges.
If x = 1, the series is ∑ 1 / (8n − 1), which diverges.
So the interval of convergence is [-1, 1).

Step-by-step explanation:
Adrianna uses her credit card to purchase everything! She makes payments on the 15th of each month. Each payment she makes is for the same amount, and it is automatically deducted from her savings account. At the end of the year, Adrianna’s account balance changed by - $4,203.00 due to the payments she made. What is the change in Adrianna’s account balance each month due to the payments she makes on her credit card?
Answer:
$350.25 per month
Step-by-step explanation:
We can assume she pays the same amount every month. We know that there are 12 months in a single year, so we can divide to find the unit rate.
4203 / 12 = 350.25
Best of Luck!
Answer:
$350.25 per month

How many deciliters are equivalent to 9 cups? Use the conversion table to find the answer. Round to the nearest tenth.
21.3 dL
42.7 dL
213.3 dL
426.6 dL
Answer:
Answer: The correct option is (a) 21.3 dL.
Step-by-step explanation: We are given to find the number of deciliters that are equivalent to 9 cups.
Given that,
1 cup = 0.237 liters.
We know that
1 liter = 10 deciliters. So, we get
0.237 liters = 0.237 × 10 deciliters = 2.37 deciliters.
This implies that
1 cup = 2.37 deciliters.
Therefore, we get
9 cups = 2.37 × 9 deciliters = 21.33 deciliters.
Rounding to nearest tenth, we get
Thus, 9 cups are equivalent to 21.3 deciliters.
Option (a) is CORRECT.

As preparation for designing a new line of business wear, a clothing manufacturer asked a large sample of department store customers, "What is your favorite color of dress shirt?" The pie chart below summarizes their responses. (a) Which color was chosen by approximately one-eighth of the customers? Select One Black Grey (b) Approximately what percentage of the customers chose White or Blue? Write your answer as a multiple of 10% - that is, 10%, 20% Pink 30%, Other Blue White (c) I 24% of the customers chose Black, approximately what percentage chose Other? 8% 16% 339
Answer:
The pie chart is missing, so I looked for similar questions (see attached image):
(a) Which color was chosen by approximately one-eighth of the customers?
Blue. There are two colors that represent approximately 15%, and they are blue or grey, but grey is a little larger so it is closer to 20%.(b) Approximately what percentage of the customers chose White or Blue?
40%. If you combine the approximate number of customers that chose either white or blue, you will get roughly 40%(c) If 24% of the customers chose Black, approximately what percentage chose Other?
In all the similar questions that I found black is much more than 24%, it clearly makes up more than 1/4 of the pie chart. I would say approximately 33%. In the attached image you can see that "other" represents between 6-7%.The easiest way to solve this is to print the image and use a protractor. If you want to calculate the area for blue, just measure the angle, e.g. ± 55°, then divide by 360° = 0.1528 = 15.28%.

1. Solve 2x < 10. Explain how to find the solution set.
Answer:
x<5
Step-by-step explanation:
you need to divide 2x by 2 which gives you x. then you do the same to the other side so (10/2) which gives you 5. this means x can be any number under 5 in order for the function to be true.

a boat leaves at noon and has a bearing of S 35 east. The boat travels at 40 miles per hour. (a) many miles south and how many miles east will the boat have traveled at 7 pm
Answer:
South =34.18 miles
East= 49.12miles
Step-by-step explanation:
We begin by calculating the distance covered in 7n hours
that is from 12 pm to 7pm which is 7 hours
so time t= 7 hours
speed= 40 miles per hours
we know that speed= distance/time
let the distance be x
40=x/7
x=40*7
x=28miles
(a) many miles south and how many miles east will the boat have traveled at 7 pm
applying SOH CAH TAO we have
For the south CAH
cos Ф=hyp/adj
hyp= 28 mile
Ф= 35°
cos 35= 28/adj
0.819=28/adj
adj=28/0.819
adj=34.18 miles
For the East SOH
sin Ф=hyp/opp
hyp= 28 mile
Ф= 35°
sin 35= 28/opp
0.57=28/opp
opp=28/0.57
opp=49.12miles
A clerk entering salary data into a company spreadsheet accidentally put an extra "0" in the highest
employee salary (the boss's salary!), listing it as $1,500,000 instead of $150,000. How does this
error affect the measures of center (median and mean)?
A. The median will be the same. The mean will be too small.
B. The median will be the same. The mean will be too large
C. The median will be too small and the mean will be too large,
D. The median and the mean will both be too large.
Answer:
The correct option is B.
Step-by-step explanation:
The median (m) is a measure of central tendency. To obtain the m, we assemble the data in arising order. If the data is odd, the m is the mid-value. If the data is even, the m is the arithmetic-mean of the two mid-values.
The mean is the average value of the data set. It is computed by dividing the sum of all the values in data set by the number of values.
So, the mean considers all the values in the data set. But the median considers only one value.
It is provided that the clerk entering salary data into a company spreadsheet accidentally put an extra "0" in the highest employee salary (the boss's salary!), listing it as $1,500,000 instead of $150,000.
The highest salary will be taken into account while the computation of mean. But it would not be considered while determining the median.
So, the median salary will remain same. But the mean salary will change.
And since the highest salary is increasing from $150,000 to $1,500,000 the mean will also increase.
Thus, the correct option is B.
