g(a)=33a−2; Find g(1)

g(1) means the value of a is 1. Replace a in the equation with 1 and solve.

33(1) - 2 = 33-2 = 31

g(1) = 31

In one town, the number of pounds of sugar consumed per person per year has a mean of 8 pounds and a standard deviation 3 of 20

lesantik [10]

Answer:

c. 1.67 standard deviations above the mean

Step-by-step explanation:

The z-score measures how many standard deviations a score X is from the mean. It is given by the following formula:

$Z = \frac{X - \mu}{\sigma}$

In which $\mu$ is the mean and $\sigma$ is the standard deviation.

A positive z-score means that X is above the mean, and a negative Z-score means that X i below the mean.

In this problem, we have that:

$\mu = 8, \sigma = 3$

Tyler consumed 13 pounds of sugar last year How many standard deviations from the mean is that?

This is Z when X = 13. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{13 - 8}{3}$

$Z = 1.67$

So this is 1.67 standard deviations above the mean.

The relationship between the input values (x) and the output values (y) is :'y is one less than a quarter of x'

sattari [20]

An equation in the form of y is y = x/4 - 1

<h3>An equation in the form y = ...</h3>

The statement is given as:

'y is one less than a quarter of x'

A quarter of x means x/4

So, we have:

y = x/4 - 1

Hence, an equation in the form of y is y = x/4 - 1

<h3>Number sentences</h3>

From the question, we have:

x = -4, -2,0, 2 and 4

Substitute these values in y = x/4 - 1

-4/4 - 1 = -2

-2/4 - 1 = -1.5

-0/4 - 1 = -1

2/4 - 1 = -0.5

4/4 - 1 = 0

The above represents the number sentences

Use quadratic formula solve .7x^2 - 28x - 7

beks73 [17]

Answer:

x = 2 + sqrt(5) or x = 2 - sqrt(5)

Step-by-step explanation using the quadratic formula:

Solve for x over the real numbers:

7 (x^2 - 4 x - 1) = 0

Divide both sides by 7:

x^2 - 4 x - 1 = 0

Add 1 to both sides:

x^2 - 4 x = 1

Add 4 to both sides:

x^2 - 4 x + 4 = 5

Write the left hand side as a square:

(x - 2)^2 = 5

Take the square root of both sides:

x - 2 = sqrt(5) or x - 2 = -sqrt(5)

Add 2 to both sides:

x = 2 + sqrt(5) or x - 2 = -sqrt(5)

Add 2 to both sides:

Answer: x = 2 + sqrt(5) or x = 2 - sqrt(5)
