Step-by-step explanation:
if the amount of time from 12:00 pm to 7:00 pm was 7 hours, you're going to need to take into account that you need to lower 50 degrees 7 times by 1.2 degrees. (50 - 1.2 times 7)
The period of function is 4 pie how many cycles of the function occur in a horizontal length of 12 pie
Answer: 3
Step-by-step explanation:
Given
The period of the function is [tex]4\pi[/tex] i.e. function completes a full cycle in this zone.
For a horizontal length of [tex]12\pi[/tex]
Number of cycles is
[tex]\Rightarrow \dfrac{12\pi }{4\pi }=3[/tex]
So, there are 3 ycles of the function in length of [tex]12\pi[/tex].

Answer:
What expressions?
Step-by-step explanation:
find three consecutive odd integers such that the sum of the last two is 15 less than 5 times the first
2n + 1 , 2n + 3 , 2n + 5
____________________________
( 2n + 5 ) + ( 2n + 3 ) = 5 × ( 2n + 1 ) - 15
4n + 8 = 10n + 5 - 15
4n + 8 = 10n - 10
Add both sides 10
4n + 8 + 10 = 10n - 10 + 10
4n + 18 = 10n
Subtract both sides 4n
4n - 4n + 18 = 10n - 4n
18 = 6n
Divide both sides by 6
18 ÷ 6 = 6n ÷ 6
n = 3
_________________________________
Thus that three numbers are :
2(3) + 1 , 2(3) + 3 , 2(3) + 5
6 + 1 , 6 + 3 , 6 + 5
7 , 9 , 11

Is there sufficient evidence to conclude that there is a linear correlation between budgets and gross receipts?

a. What are the null and alternative hypotheses?i) H_0: rho = 0, H_1: rho < 0
ii) H_0: rho = 0, H_1: rho notequalto 0
iii) H_0: rho notequalto 0, H_1: rho = 0
iv) H_0: rho = 0, H_1: rho > 0
b. Construct a scatterplot. Choose the correct graph below.
c. The linear correlation coefficient r is.
d. The test statistic t is.
e. The P-value is.
Answer:
Pvalue > α ; Hence, we fail to reject the null.
Step-by-step explanation:
When testing for correlation :
Correlation Coefficient r is always between - 1 and 1. The alternative is always the opposite of the null. To claim that correlation exists, the r will not be equal to 0, because 0 means no correlation.
1.)
H_0: rho = 0,
H_1: rho notequalto 0
2.)
Given the data :
Budget(x) : 61 92 48 36 135 58 93
Gross(y) : 69 62 53 58 627 144 42
Scatter plot is attached below
3.) The linear correlation Coefficient as obtained using technology is 0.751 ; which depicts a strong positive correlation
4.)
Test statistic :
T = r / √(1 - r²) / (n - 2)
r² = 0.751² = 0.564
T = 0. 751 / √(1 - 0.564) / (7 - 2)
T = 0.751 / 0.2952964
T = 2.543
E.)
Using the Value from Tscore calculator :
Pvalue(2.543, 5) ; two tailed
Pvalue = 0.0517
At α = 0.05;
Pvalue > α ; Hence, we fail to reject the null. there is no sufficient evidence to conclude that there is a linear correlation between budgets and gross receipts.

He first filled a 80 ounce mixing bowl with 8 large cups and 4 medium cups of liquid. 4 large cups and 12 medium cups of liquid. How many ounces each cup holds?
Answer:
L = 16oz
M = 12oz

Step-by-step explanation:
8 large equal to 128oz ( 8 x 16 = 128 )
4 medium equal to 48oz ( 4 x 12 = 48
4 large equal to 64oz ( 4 x 16 = 64
12 medium equal to 144oz ( 12 x 12 = 144 )
Total of oz equal 384oz

Answer:
y = -1.5x +3
Step-by-step explanation:
The two points marked on the line are ...
(-4, 9) and (6, -6)
The slope formula can be used to find the slope:
m = (y2 -y1)/(x2 -x1)
m = (-6 -9)/(6 -(-4)) = -15/10 = -1.5
The intercept formula can be used to find the y-intercept:
b = y -mx
b = 9 -(-1.5)(-4) = 9 -6 = 3
The slope-intercept form of the equation for a line is ...
y = mx + b . . . . . . . line with slope m and y-intercept b
y = -1.5x +3
_____
Additional comment
We can see that the line crosses the y-axis at y=3, so this is the value of b. We only need to read it from the graph. We don't really need the formula shown above.
The line also crosses the x-axis at x=2. This means the line decreases 3 units (from y=3 to y=0) as x increases by 2 units (from x=0 to x=2). Then the slope is ...
m = rise/run = (-3)/(2) = -3/2 = -1.5 . . . . as calculated above
That is, we can find the parameters of interest by simply counting grid squares on the graph.

What is the average rate of change for this quadratic function for the interval from x = 0 to x = 2?
Answer:
8
Step-by-step explanation:
The average rate of change for this quadratic function for the interval from x = 0 to x = 2 is -2
What is a function?A relation is a function if it has only One y-value for each x-value.
The average rate of a function f(x) from x=a to x=b is given as:
= f(b)-f(a)/b-a
Clearly we are asked to find the average rate of change from x=0 to x=2.
i.e. a=0 and b=2
Also, from the graph it could be observed that:
f(0)=1
and f(2)=-3
=f(2)-f(0)/2-0
=-3-1/2
=-4/2
=-2
Hence, the average rate of change for this quadratic function for the interval from x = 0 to x = 2 is -2

Step-by-step explanation:
Answer:
7. all of the above
9. none of these
Step-by-step explanation:
graph number 7
you will see from the diagonal test that the diagonals of this shape are congruent. All four angles in the interior are congruent making it a rhombus. The outside side lengths are all equal to 6.71. Making it a rectangle. The definition of a square is if it is both a rectangle and a rhombus then it is a square.

Jack took out a 6-year loan for $25,000 to purchase a boat at a 4.5% interest rate. If the interest is compounded monthly, what will he have paid total over the course of the loan?
Answer: $32,732.58
Step-by-step explanation:
To calculate the total loan payment over the course of the loan period, use the future value formula:
= Loan amount * (1 + rate) ^ number of years
As this loan is compounded monthly, you need to convert certain terms to monthly figures:
Number of periods = 6 * 12 months = 72 months
Interest = 4.5 / 12 = 0.375%
Total payment:
= 25,000 * ( 1 + 0.375%)⁷²
= $32,732.58
He will have to pay $34,236.31 over the course of the loan.
Using the compound interest formula expressed as:
[tex]A =P(1+r/n)^{nt}[/tex]
P is the principal = $25000
r is the rate = 4.5% = 0.045
t is the time in years = 6 years
n is the compounding amount = (12)monthly
Substitute into the formula:
[tex]A =25000(1+0.045/12)^{12(7)}\\A=25000(1.36945)\\A = \$34,236.31[/tex]
Hence he will have to pay $34,236.31 over the course of the loan

One package of cookies contains 3,460 calories. Each serving of cookies contains 72 calories. About how many servings are in the package?
Answer:
Number of servings= 48.05
Step-by-step explanation:
Giving the following information:
One package of cookies contains 3,460 calories. Each serving of cookies contains 72 calories.
To calculate the number of servings, we need to use the following formula:
Number of servings= total calories / calories per serving
Number of servings= 3,460 / 72
Number of servings= 48.05

An amusement park has two featured rides that require an additional ticket, the Slingshot and the Scream Flyer. On a summer day, 1279 visitors entered the park. 280 visitors bought tickets for either the Slingshot or the Scream Flyer. 247 visitors bought a ticket for the Slingshot and 237 visitors bought a ticket for the Scream Flyer. What is the probability that a randomly selected visitor bought tickets for both the Slingshot and the Scream Flyer
Answer: [tex]\frac{204}{1279}[/tex]
Step-by-step explanation:
Formula for intersection:
n(A and B) = n(A)+n(B)-n(A or B)
Given: n(Slingshot) = 247
n(Scream Flyer)= 237
n(Slingshot or the Scream Flyer) = 280
n (Slingshot and Scream Flyer)= 247+237-280
=204
Probability of any event = [tex]\frac{\text{Number of favourable outcomes}}{\text{total outcomes}}[/tex]
P(both the Slingshot and the Scream Flyer)= [tex]\frac{204}{1279}[/tex]
Required probability = [tex]\frac{204}{1279}[/tex]
A website 500,000 members in 2010. The number y of members increases by 15% each year. Write an exponential growth function that represents the website membership t years after 2010. How many members will there be in 2016? Round your answer to the nearest ten thousands
Answer:
a = 500,000(1.15)^t
1,160,000
Step-by-step explanation:
a = 500,000(1.15)^t
in 2016
a = 500,000(1.15)^6
a = 1,156,530
Rounded
1,160,000
The number of members present in 2016 is 1,156,530. It can be rounded to 1,160,000.
What is an exponential function?
The function is expressed in the form like f(x) = a^x are called exponential function. Where x is a variable and a is a constant.
The number of members in the website in 2010 is 500,000.
Each year y members increased by 15%.
The exponential relation of members and year is
y = 500,000(1.15)^t
Then in 2016 the number of members present are given by,
y = 500,000(1.15)^6 = 1,156,530.
Hence, 1,156,530 members present in 2016. It can rounded to 1,160,000.
