What is the measure of angle 1?
y=−8x−3
x+y=7
Is (3,4) a solution of the system?
Answer:
No
Step-by-step explanation:
The given point does not satisfy the first equation.
y = -8(3) -3 = -27
4 ≠ -27 . . . . . the first equation is not satisfied.
Answer: No
Step-by-step explanation:
Plug x and y into y=-8x-3 and calculate:
4 = -24 - 3
4 ≠ 27
Therefore (3,4) is not a solution of the system of equations.

In the first week of July, a record 1,020 people went to the local swimming pool. In the second week, 125 fewer people went to the pool than in the first week. In the third week, 145 more people went to the pool than in the second week. In the fourth week, 224 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
Answer:
The percent decrease in the number of people who went to the pool over these four weeks was of 20%.
Step-by-step explanation:
Percent decrease:
The percent decrease is the decrease multiplied by 100 and divided by the initial value.
Decrease was of:
Second week: - 125
Third week: - 125 + 145
Fourth week: -125 + 145 - 224 = -204
Decrease was of 204.
Percent decrease:
Initially 1,020, then a decrease of 204. So
204*100%/1020 = 20%
The percent decrease in the number of people who went to the pool over these four weeks was of 20%.
Answer: 20%

Suppose that a population parameter is 0.7 and many samples are taken from the population. If the size of each sample is 100, what is the standard error of the distribution of sample proportions?
Answer: .046
Step-by-step explanation: I just had this question
The statement : "for a sample size of n = 26 and a population parameter of p = 0.6, a normal curve can be used to approximate the sampling distribution" is true.
What is normal curve?Normal curve is used to represent the class shapes in the statistical probability. Mathematically, we can describe the normal curve as -
[tex]$f(x)= {\frac{1}{\sigma\sqrt{2\pi}}}e^{- {\frac {1}{2}} (\frac {x-\mu}{\sigma})^2}[/tex]
where -
f(x) = probability density function
σ = standard deviation
μ = mean
Given is that for a sample size of n = 26 and a population parameter of
p = 0.6, a normal curve can be used to approximate the sampling
distribution.
It is asked to identify whether the given statement regarding the normal curve is true or false. The given statement is - "for a sample size of n = 26 and a population parameter of p = 0.6, a normal curve can be used to approximate the sampling distribution". The given statement is true.
Therefore, the statement : "for a sample size of n = 26 and a population parameter of p = 0.6, a normal curve can be used to approximate the sampling distribution" is true.

8 Mangoes = 30 bananas
5 banana= 2 oranges
15 oranges=? mangoes
Answer:
it would only be 8, unless you need to go down to the decimal point then it would be 8.25
Step-by-step explanation:
it would be 8 because if you need to find how many bananas you have, to do this you would divide 15 by 2 and get 7.5 then you multiply those by 5 to get the number of bananas which would be 37.5, and then if 8 mangos = 30 bananas you only have 8 mangos.

Help #1-4 please please just add the symbol addition , subtraction , multiplication or division . I tried 1.subtraction 2&3 division & 4 multiplication but they are wrong so please help
Problem 1
Operation = Subtraction
Estimated answer = 8 dollars
----------------------------
Explanation:
The regular price is estimated at $45, while the sale price is estimated at $37. The two subtract to get 45-37 = 8 dollars, which is about how much you save if you go for the discount price.
The actual amount saved is 45.32-36.50 = 8.82
==========================================================
Problem 2
Operation = Division
Estimated answer = 75 cents
----------------------------
Explanation:
$3.45 rounds to $3
Divide this over 4 to get 3/4 = 0.75, meaning each battery is 75 cents
The actual cost per battery is 3.45/4 = 0.86 dollars = 86 cents.
==========================================================
Problem 3
Operation = Division
Estimated answer = $10
----------------------------
Explanation:
Round $37.45 to the nearest ten to get $40; we could round to 37 but that's an oddball number in my opinion compared to 40. Plus 40 is divisible by 4, leading to 40/4 = 10. Each person chips in about 10 dollars.
The actual amount each person pays is 37.45/4 = 9.36
==========================================================
Problem 4
Operation = Multiplication
Estimated answer = 180 miles
----------------------------
Explanation:
18.75 rounds to 20, which we multiply by 9 to get 180
So the car can travel about 180 miles on 9 gallons. This is an overestimate because 18.75 rounded up to 20
The actual value is 18.75*9 = 168.75

What is the area of a circle with a radius of 13 millimeters? (use 3.14 for pi)
===============================================
Work Shown:
A = pi*r^2
A = 3.14*13^2
A = 3.14*169
A = 530.66 square millimeters
We can abbreviate "square millimeters" into "square mm" or into "mm^2".
This value is approximate because pi = 3.14 is approximate.

what is the x intercept of the graph of y=4x-36
Answer:
36
Step-by-step explanation:
My explanation to this is that if you look at the problem it will show you 36.
Answer:
9
Step-by-step explanation:
To find the x-intercept, set y = 0
0 = 4x-36
Add 36 to both sides:
0+36 = 4x-36+36
36 = 4x
Divide by 4 on both sides:
36/4 = 4x/4
9 = x
The x-intercept is 9
Write a sine function that has an amplitude of 5, a midline of 2 and a period of 8pi/5.
Answer:
f(x) = 5*sin( (5/4)*x) + 2
Step-by-step explanation:
A general sine function can be written as:
f(x) = A*sin(w*x) + M
Where:
A is the amplitude
w is the frequency of the function
M is the midline
Here we know that we want to have:
An amplitude of 5. Then, A = 5
A midline of 2, then M = 2
And a period of (8/5)*pi
For now, we can write our function as:
f(x) = 5*sin(w*x) + 2
Now, we know that for a function of period T, is always true that:
f(x) = f(x + T)
here, the period is T = (8/5)*pi
knowing that sin(0) = sin(2*pi)
Then we must have:
sin(0) = sin(w*0) = sin(w*( 0 + (8/5)*pi)) = sin(2*pi)
Then the arguments of the third and fourt parts must be the same, thus:
w*(8/5)*pi = 2*pi
We can solve this for w now:
w*(8/5) = 2
w = 2*(5/8) = (5/4)
Then the function is:
f(x) = 5*sin( (5/4)*x) + 2
