Answer:
Step-by-step explanation:
I don't have a graph but I'll tell you how to graph. You have to graph this as an mx+b equation. Since this doesn't have a y-intercept, you'll start at 0 on the graph. Go up 2 times and over to the right 1 time. You should be at (1,2) do the same thing and you should be at (2,4) continue till you run out of the provided space. Now, go back to 0 and complete the part below it. To complete that, from 0, go down 2 times and over to the left 1 time. You should reach (-1,-2) and when you do the same thing again, you should reach (-2,-4) and continue until you run out of space. The coordinates o=in which the line touches should be the opposites of the coordinates above 0. Like (1,2) (-1,-2) and (2,4) (-2,4).

1 9/10 + 3/4 plz need help I’m tired and can’t do math I also need it simplified
Answer:
4
Step-by-step explanation:
take 1 9/10 change it to 19/10 + 3/4. You will need to have a common denominator for any addition or subtraction with fractions. We multiply 19/10 by 4 to get 76/40. Multiply 3/4 by 10 to get 30/40. Now we have a common denominator.
Add across 76 + 30 = 106/40. Now simplify. How many times does 40 go into 106?
4 times. No remainder.

The area of a parallelogram can be found by the equation area = (b)(h)
Find the height of a parallelogram that has an area of 10 1/2 in² and a base of
¾ in.
The height of the parallelogram is ( ) inches.
21/2=(3/4) (h)
(4/3) (21/2) = (4/3) (3/4) (h)
Answer: Height = 14
Step-by-step explanation: 10.5 / 0.75 = 14
Answer:
The height is 14 inches
Find the z-score such that: a. The area under the standard normal curve to its left is 0.5 b. The area under the standard normal curve to its left is 0.9826 c. The area under the standard normal curve to its right is 0.1423 z
Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the mean is above or below the raw score. If the z score is positive then the raw score is above the mean while if the z score is negative then the raw score is below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma}\\ \\\mu=mean, \sigma=standard\ deviation[/tex]
a)
From the normal distribution, 0.5 corresponds to a z score of 0.
z = 0.
b) From the normal distribution, an area of 0.9826 to the left corresponds to a z score of 2.11.
c) An area to the right of 0.1423 = an area of 0.8577 ( 1- 0.1423) to the left. From the normal distribution, an area of 0.8577 to the left corresponds to a z score of 1.07
You must be in degree mode to find sin pie/3
A.) True
B.) False
Answer:
(i) False. Let A = 30° and B = 60°, then sin (A + B) = sin (30° + 60°) = sin 90° = 1 and, sin A + sin B = sin 30° + sin 60° = 1/2 + √3/2 = 1+√3/2(ii) True. sin 0° = 0 sin 30° = 1/2 sin 45° = 1/√2 sin 60° = √3/2 sin 90° = 1 Thus the value of sin θ increases as θ increases.(iii) False. cos 0° = 1 cos 30° = √3/2 cos 45° = 1/√2 cos 60° = 1/2 cos 90° = 0 Thus the value of cos θ decreases as θ increases.(iv) True. cot A = cos A/sin A cot 0° = cos 0°/sin 0° = 1/0 = undefined.

Answer:
he can do things that well give him money
Step-by-step explanation:
Answer:
below
Step-by-step explanation:
First, you must find the total he has: $10
Then, you must find how much he need: $13
Then, you take the smaller number to take away from the greater number: 13-10
Finally, you subtract those two numbers to find the amount the Juan needs: $3
In a test with a mean of 100 and a standard deviation of 10, what is the standard deviation for a test score of 120
This question is incomplete
Complete Question
In a test with a mean of 100 and a standard deviation of 10, what is the standard score for a test score of 120?
Answer:
The standard score = 2
Step-by-step explanation:
The formula for Test (T) score is given as:
T score = zσ + μ
z = Standard or z score = ??
Standard deviation (σ) = 10
Mean (μ) = 100
Test score = 120
120 = 10z + 100
120 - 100 = 10z
20 = 10z
z = 20/10
z= 2
Therefore, the standard score = 2
A university is proposing a new procedure for professors to gain tenure. To gauge sentiment about the proposal, the university intends to randomly sample five professors, five assistant professors, five associate professors, five adjunct professors, and five visiting professors. This is an example of what type of sampling design
Answer:
The correct answer is:
stratified sampling
Step-by-step explanation:
Stratified sampling is a type of sampling method where the population to be sampled is divided into subgroups or strata and then random selection is made, and these strata are formed based on some shared common characteristics. In this example, the population to be sampled is a population of professors, but the researcher went further to divide this group into professors, assistant professors, associate professors, adjunct professors, and visiting profesors.

Arbaz's mom reminds him that he also needs to purchase car insurance. Arbaz finds a
car insurance policy that will cost him $150 a month for the first 12 months. The cost
is expected to decrease by 3.2% each year he has his license. How much is Arbaz
expected to pay, monthly, after one year? Show your work and explain your answer.
Answer:
Arbaz is expected to pay $145.2 every moth after one year.
Step-by-step explanation:
We know that 150 dollars is owed every month. And after every 12 months the cost he has to pay a month decreases by 3.2% meaning we have to find what 3.2% is of 150. So we convert 3.2 into a decimal getting us 0.032
150 x 0.032 = 4.8
Now we know what 3.2% is of 150 so we subtract 4.8 from 250 and get 145.2
150 - 4.8 = 145.2

shoppers enter hamilton place mall at an average of 120 per hour what is the probability that at least 20 shoppers
This question is incomplete, the complete question is;
Shoppers enter Hamilton place mall at an average of 120 per hour
what is the probability that at least 20 shoppers but no more than 23 shoppers enter the mall between noon and 12:30 p.m.?
Answer:
the probability that at least 20 shoppers but no more than 23 shoppers enter the mall between noon and 12:30 p.m
is 4.20787 × 10⁻⁸ ≈ 0.0000000420787
Step-by-step explanation:
the probability that at least 20 shoppers but no more than 23 shoppers enter the mall between noon and 12:30 p.m;
interval between noon and 12:30 is 30min
now the shoppers enter an average of [(120 × 30) / 60] = 60 per 30min
so
P( 20 ≤ X ≥ 23 ) = P( X=20 ) + P( X=21 ) + P( X=22 ) + P( X=23 )
= [(e⁻⁶⁰(60)²⁰) / 20!] + [(e⁻⁶⁰(60)²¹) / 21!] + [(e⁻⁶⁰(60)²²) / 22!] + [(e⁻⁶⁰(60)²³) / 23!]
= [1.3159 × 10⁻⁹] + [3.7598 × 10⁻⁹] + [1.0254 × 10⁻⁸] + [2.6749 × 10⁻⁸]
= 4.20787 × 10⁻⁸ ≈ 0.0000000420787
therefore the probability that at least 20 shoppers but no more than 23 shoppers enter the mall between noon and 12:30 p.m is 4.20787 × 10⁻⁸ ≈ 0.0000000420787

Fine the area of this figure round your answer to the nearest hundredth use 3.14 to approximate
This value is approximate because we used the approximation pi = 3.14
=================================================
Explanation:
For problems like this, a common approach is to break the figure into smaller pieces. Find the area of each small piece, then add up those individual areas to get the full area we're after.
------------
A = area of triangle
A = 0.5*base*height
A = 0.5*6*8
A = 24 square feet
-----------
B = area of the semicircle with radius r
B = 0.5*(area of full circle with radius r)
B = 0.5*(pi*r^2)
B = 0.5*pi*r^2
B = 0.5*3.14*4^2 .... the diameter is 8, radius is half that
B = 25.12 square feet
--------------
C = area of the full figure
C = A+B
C = 24+25.12
C = 49.12 square feet

alone is 11. Find the numbers.
Answer:
2x + 3 = 15
x = 6
2(6) + 3 = 15
Step-by-step explanation:
This is the answer because:
1) 2 x 6 = 12, 12 + 3 = 15
2) 2 + 6 + 3 = 11
Therefore, the answer is 2(6) + 3 = 15
Hope this helps!
Answer:
x=6

1.If x and y vary directly and y = 16 when x = 12, then which of the following equations correctly represents the relationship between x and y?
Answer:
[tex]y = \frac{4}{3}x[/tex]
Step-by-step explanation:
Given:
Variation: Direct Variation.
This can be represented as:
[tex]y\ \alpha\ x[/tex]
[tex]y = 16; x = 12[/tex]
Required
Write out the equation
First, the variation has to be converted to an equation
[tex]y\ \alpha\ x[/tex]
[tex]y = kx[/tex]
Where k represents constant of variation.
Substitute 16 for y and 12 for x
[tex]16 = k * 12[/tex]
Solve for k
[tex]k = \frac{16}{12}[/tex]
[tex]k = \frac{4}{3}[/tex]
To get the equation, we simply substitute 4/3 for k in [tex]y = kx[/tex]
[tex]y = \frac{4}{3}x[/tex]
