Answer:
The width of the window is 176 cm
Step-by-step explanation:
The perimeter is the outside of a shape. If the perimeter is 242 cm and we know the length is 66 cm, we use what we have. We take 242 and subtract it by 66 and get 176 cm

Answer:
13.3 (rounded in the tenth place)
Step-by-step explanation:
equation: a^2 + b^2 = c^2
What we know :
a = 20^2 = 400
b = what we are looking for
c = 24^2 = 576
Our equation will be looking like :
20^2 + b^2 = 24^2
400 + b^2 = 576
Now we subtract 400 into 576
which equals 176 now we square root it
and get 13.2664 but we gotta square root it and that will lead you to have 13.3 as your answer
Answer:
31.24
Step-by-step explanation:
a^2+b^2=c^2
20^2=400
24^2=576
576+400=976
√976=31.24

Which of the following is an appropriate test for the investigation?
Answer:
B
Step-by-step explanation:
I don't know
An appropriate test for the investigation is, One sample t-test for sample mean. So option B is correct
What is a random sample ?The process of selecting a sample of data from a population in order to draw conclusions about the population is known as random sampling. Additionally known as probability sampling. Non-probability sampling, often known as non-random sampling, is this sample's opposite. Simple random sampling, stratified sampling, cluster sampling, and multistage sampling are the main forms of this sampling. Convenience samples are often referred to as non-arbitrary samples in sampling methodologies.
Given that,
Population mean = $100
Sample = n = 56
Sample mean = $102.30
sample standard deviation = $5.30
So, all the data mean, standard deviation is given
therefore, t-test used and one type of sample used as well
Hence, It is one-sample t-test for sample mean

What is the area of a circle with a diameter of 18.2 cm?
Use 3.14 for ∏ and round your final answer to the nearest hundredth.
The area is ___ square cm.
Answer: 260.16 cm
Step-by-step explanation:
Select all expressions that are equivalent to 8(5t + 7v).
A. 2(20t + 28V)
B.4(95 + 11v)
C.40t + 7v
D.40t + 56v
The expression 8(5t+7v) is equivalent to the expression 2(20t+28V) and 40t + 56v option (A) and option (D) is correct.
What is distributive property?The distributive property is the property that expresses the distributive law of algebraic multiplication. similarly, in polynomial expression we can use the distributive property for example we can write a(c+b) in the form of (ac+bc).
We have an expression:
= 8(5t+7v)
After using the distributive property, we get:
= 8×5t+8×7v
= 40t + 56v
Applying distributive property in the expression 2(20t+28v), we get:
= 2×20t+2×28v
= 40t+56v
The above expression is equivalent to the given expression.
Again applying distributive property in the expression 4(95+11v), we get:
= 4×95+4×11v
= 380+44v
The above expression is not equivalent to the given expression.
The expression 40t+7v is not equivalent to the given expression.
The expression 40t+56v is equivalent to the given expression.
Thus, the expression 8(5t+7v) is equivalent to the expression 2(20t+28V) and 40t + 56v option (A) and option (D) is correct.

Find a and b given f(x) = ax + b, f(1) = 7, and f(3) = -5.
Answer:
a = - 6, b = 13
Step-by-step explanation:
Given f(1) = 7 , that is f(x) = 7 when x = 1
f(3) = - 5 , that is f(x) = - 5 when x = 3
Substitute these values into f(x) = ax + b
a + b = 7 → (1)
3a + b = - 5 → (2)
Subtract (1) from (2) term by term to eliminate b
(3a - a) + (b - b) = - 5 - 7
2a = - 12 ( divide both sides by 2 )
a = - 6
Substitute a = - 6 into either of the 2 equations and solve for b
Substituting into (1)
- 6 + b = 7 ( add 6 to both sides )
b = 13
