Step-by-step explanation:
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

Step-by-step explanation:
A water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area formed by the watering pattern is 907.46 square feet? Use 3.14 for π
Answer:
The number of feet away from the sprinkler where it could spread water would be the radius of the circle in which it is spraying.
The Area of a circle is
πr2=808.64
(3.14)r2=808.64
Divide both sides by 3.14
r2=257.5286624
Square root both sides to get radius
r=16 feet
7 feet away from the sprinkler can it spread water if the area formed by the watering pattern is 907.46 square feet
Area of circle:What information do we have?
Area of watering pattern = 907.46 square feet
Area of watering pattern = Area of circle
Area of watering pattern = πr²
907.46 = (3.14)r²
r² = 289
r = 17
Length = 17 feet

6th grade work fast and easy
Answer: 56 times
Step-by-step explanation:
If his ratio of goals to misses is
6:7
then we must find out how many times he missed seeing he scored 48
so
48:?
to solve find out if 6 goes into 48 and it does 8 times so multiply both sides by 8 to get the new ratio
6*8:7*8
48:56
So the new ratio is 48:56 which also means he missed 56 shots

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.

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
