Answer:
the answer is 11
Step-by-step explanation:
4 times 2 is 8 plus 3= 11
Answer:
So you are going to put it in like this
4(2) + 3
Now multiply 4 times 2 and you get
8 + 3
Now add 8 to 3 and you get
11

The length of a rectangular picture frame is 16 inches, and the width of the picture frame is 12 inches. What is the length of a diagonal of this picture frame in inches?
Answer:
20 inches
Step-by-step explanation:
A rectangular object can instead be thought about as two right triangles with the hypotenuse being the diagonal we are solving for.
With this in mind the Pythagorean Theorem can be used to solve for c
c^2=a^2+b^2
A=16 inches
B= 12 inches
C= hypotenuse
C^2=16^2+12^2
C^2=256+144
C^2=400
Take the square root of both sides: C = 20 inches

A company’s call center advertises that they resolve 80% of its customer calls by using automated voice options. A customer who has called in many times and rarely had issues resolved through the automated options believes that 80% is an overstatement. A significance test was done, and a test statistic was calculated. Assume the conditions for inference were met.
H0: p = 0.80
Ha: p < 0.80
p = The true proportion of all customer calls that are resolved by using automated options
Calculate the P-value, given that the resulting test statistic was z = –1.389.
Answer:
1. State the claim H0 and the alternative, Ha
2. Choose a significance level or use the given one.
3. Draw the sampling distribution based on the assumption that H0 is true, and shade the area
of interest.
4. Check conditions. Calculate the test statistic.
5. Find the p-value.
6. If the p-value is less than the significance level, α, reject the null hypothesis. (There is enough
evidence to reject the claim.)
If the p-value is greater than the significance level, α, do not reject the null hypothesis.
(There is not enough evidence to reject the claim.)
(You can use the p-value to make a statement about the strength of the evidence against H0
without using α, e.g., p>.10 implies “little or no evidence against H0”, .05< p ≤ 10 implies
“some evidence against H0”, .01 < p ≤ .05 implies “good evidence against H0”, .001 < p ≤ .01
implies “strong evidence against H0”, p ≤ .001 implies “very strong evidence against H0”.)
7. Write a statement to interpret the decision in the context of the original claim.

A recipe requires 3/4 cups of milk. Paula is making 1/2 of the recipe. How many cups of milk will Paula use?
Answer:
3/8
Step-by-step explanation:
3/4 x 1/2 = 3/8
There are 3 / 8 cups of milk will Paula use.
What is mean by Multiplication?Multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A recipe requires 3/4 cups of milk.
And, Paula is making 1/2 of the recipe.
Now, We get;
Number of cups of milk will Paula use is,
⇒ 3 / 4 x 1 / 2
⇒ 3 / 8
Thus, There are 3 / 8 cups of milk will Paula use.

could someone help
Answer:
P = -5
Step-by-step explanation:
First try to get the variable p by its self and the whole numbers on the opposite side.
14p - 8 = 22 + 20p
-14p - 14 p
-8 = 22 + 6p
-22 -22
-30 = 6p
Then divide to get P alone
-30 = 6p

A student with a mass of 65 kg steps on an improvised raft. He then moves at a speed of 2.0 m/s to cross a flooded street. With what velocity does the raft move assuming it has a mass of 25 kg?
Answer: 0.2 m/s
Step-by-step explanation:
The student steps on the raft, and then he moves (with the raft) at a speed of 2.0m/s to cross the flooded street.
Then the raft moves with him, at the same speed (notice that the mass of the raft does not matter, suppose that you move at 100km/h in a small car, the speed of the vehicle would be exactly the same as if you where in a truck moving at 100km/h)
Then the speed of the raft is also 2.0 m/s.

3. For babysitting, Nicole charges a flat fee of $3, plus $5 per hour. Write an equation for the cost, C, after h hours of babysitting. What do you think the slope and the yintercept represent? How much money will she make if she baby-sits 5 hours?
Answer:
a) C = 3 + 5h
b) Slope = 5
y - intercept = 3
c) $28
Step-by-step explanation:
For babysitting, Nicole charges a flat fee of $3, plus $5 per hour.
a) Write an equation for the cost, C, after h hours of babysitting.
The equation for the cost C is given as:
C = $3 + $5 × h
C = 3 + 5h
b) What do you think the slope and intercept represent?
The equation of a straight line is represented by
y = mx + c
Where
Slope = m and y-intercept = c
Comparing this with our equation in a
C = 3 + 5h = C = 5h + 3
mx = 5h
c = 3
Therefore,
Slope = 5
y - intercept = 3
c)How much money will she make if she baby-sits 5 hours?
We have our equation above as:
C = 3 + 5h
h = 5 hours
Hence,
C = 3 + 5 × 5
C = 3 + 25
C = $28
She would make $28

Margo can purchase tile at a store for $0.69 per tile and rent a tile saw for $28. At another store she can
borrow the tile saw for free if she buys tiles there for $1.39 per tile. How many tiles must she buy for the
cost to be the same at both stores?
Answer:
30 tiles need to buy for same cost in both store.
Step-by-step explanation:
Let x be the number of tiles to buy for same cost in both store.∴18+0.69⋅n=1.29⋅n∴ 1.29n − 0.69n = 18 or 0.6n =18∴n=180.6=30 Therefore, 30 tiles need to buy for same cost in both store
