4 0

Answer:

85

Step-by-step explanation:

Given data

Abby test scores 95, 82, 78, 88

We see that the number of test

n is 4

Hence the average test score is

Average score = ∑scores/n

Average score = 95+82+78+88/4

Average score = 343/4= 85.75

≈ the average test score is 85

First four terms of f(n)=3n-1
gavmur [86]
First four terms would be n = 1, 2, 3, 4

f(1) = 3 ( 1 )( 1 + 3 )
= 3 * 4
=12
f(2) = 3 ( 2 )( 2 + 3 )
= 6 * 5
= 30
f(3) = 3 ( 3 )( 3 + 3 )
= 9 * 6
= 54
f(4) = 3 ( 4 )( 4 + 3 )
= 12 * 7
= 84 hope this helps!

Find the value of x. Round to the nearest tenth.
Aliun [14]

Answer:

Step-by-step explanation:

Triangle XYZ is a right angle triangle.

From the given right angle triangle

XZ represents the hypotenuse of the right angle triangle.

With ∠34 as the reference angle,

YZ represents the adjacent side of the right angle triangle.

XY represents the opposite side of the right angle triangle.

To determine x, we would apply the Cosine trigonometric ratio

Cos θ = opposite side/hypotenuse. Therefore,

Cos 34 = x/28

x = 28Cos34 = 28 × 0.8290

x = 23.212

To the nearest tenth, it becomes

23.2

Write -5x-12y=12 in slope intercept form
TiliK225 [7]

Answer:

y = (-5/12)x - 1

Step-by-step explanation:

The fastest way in which to express -5x-12y=12 in slope-intercept form is to solve -5x-12y=12 for y:  

Add 5x to both sides, obtaining -12y = 12 + 5x.

Next, divide both sides by -12, obtaining   y = -1 - (5/12)x, or y = (-5/12)x - 1.
