Answer:

g(4) = 13

Step-by-step explanation:

$g(r) = 25 - 3r \\ plug \: r = 4 \\ g(4) = 25 - 3 \times 4\\ g(4) = 25 - 12 \\ \huge \purple { \boxed{ g(4) = 13}}$

Identify whether each of the following expression is a quadratic expression in one variable. Give reason for your anwser

ladessa [460]

I believe anything that is squared (^2) is a quadratic. so a, b, e and f are quadratics. you could also check on desmos to see if they are parabolas (u shape).

Find the angle measures of a triangle if the first angle is thirty-one degrees more than the second, and the third is five degre

MAVERICK [17]

Answer:

23°, 54°, 103°

Step-by-step explanation:

let the2nd angle = x

1st angle = x + 31

3rd angle = 2(x + 31) - 5 = 2x + 62 - 5 = 2x + 57

Sum the 3 angles and equate to 180

x + 31 + x + 2x + 57 = 180 , that is

4x + 88 = 180 ( subtract 88 from both sides )

4x = 92 ( divide both sides by 4 )

x = 23

Then

1st angle = x + 31 = 23 + 31 = 54°

2nd angle = x = 23°

3rd angle = 2x + 57 = 2(23) + 57 = 46 + 57 = 103°

One senior from the high schools will be selected at random. What is the probability that the senior selected will not be from h

DochEvi [55]

Using the probability concept, it is found that there is a 0.7361 = 73.61% probability that the senior selected will not be from high school b given that the senior responded with a choice other than college.

<h3>What is a probability? </h3>

A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Researching the problem on the internet, it is found that:

538 seniors responded with a choice other than college.

Of those students, 99 + 83 + 49 + 31 + 63 + 71 = 396 are not from high school b.

Hence:

$p = \frac{396}{538} = 0.7361$

0.7361 = 73.61% probability that the senior selected will not be from high school b given that the senior responded with a choice other than college.

Please help thank you.

Hello!

To solve this we use the equation sin60 = (s/2) / (d/2)

s is a side of the triangle
d is the diameter

sin60 = s/d

$\sqrt{3/4} =s/d$

$d=s/ \sqrt{3/4}$

$d = s \sqrt{4/3}$

$d = 2s/ \sqrt{3}$

put 6 in for s

$d=12/ \sqrt{3}$

$d = \sqrt{48}$

d = 6.9

The answer is C) 6.9

Hope this helps!
