Step-by-step explanation:

Answer:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.

Answer:

ΔABC ≅ ΔQPR

Step-by-step explanation:

if you were to reflect it, they would line up also A ≅ Q because their angles are the same and I know that because of the markings, they both have one arc and B and P both have two arcs meaning they are congruent and C and R both have three arcs so they are congruent.

Answer:

83

Step-by-step explanation:

The measure of the side v for the triangle is 82.8 inches.

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that in ΔUVW, w = 79 inches, u = 57 inches and ∠V=73°. The measure of the side v is calculated by the formula,

v² = u² + w² - 2uvcosv

v² = ( 57)² + (79)² - 2 x 57 x 79 x cos73

v² = 6856.9

v =√6856.9

v = 82.8 inches

Hence, the value of v will be 82.8 inches.

Answer:

95 ° 36 ′ 36 ′′

Step-by-step explanation:

To convert 95.61 into degrees, minutes and seconds, you'll have to leave the whole units of degrees alone. You have to multiply the decimal by 60. The whole number becomes the minutes.

Then, you multiply 0.61 by 60, in which you get 36.6.

Take the remaining decimal and multiply by  60  and take the whole number portion to find the seconds.

Multiply 0.6 by 60. You get 36.

And lastly, Take the three sets of whole numbers and combine them, using the symbols for degrees ( ° )  , minutes  ( ′ ) , and seconds  ( ′′ ) .

This is how you get 95 ° 36 ′ 36 ′′.

Answer:

Phone B

Step-by-step explanation:

It is around the same cost as Phone C, but has unlimited data (which means unlimited gigs)

Answer:

B

Step-by-step explanation:

Charge of 9 gigs for A

find slope:

125 - 95/5 - 3 = 30/2 = $15/month

use point slope form with point (3,95) and slope 15:

y - y1 = m(x - x1)

y - 95 = 15(x - 3)

y - 95 = 15x - 45

 + 95           +95

y = 15x + 50

put 9 for x, gigs, in the new equation:

y = 15(9) + 50

y = 135 + 50

y = 185

$185 for opt A

Charge of 9 gigs for B

slope = 0

there is the fee of 150 so the equation is:

y = 0x + 150

Next find the price for 9 gigs

y = 9(0) + 150

y = 150

$150 for opt B

Charge of 9 gigs for C

use graph and the cost is about $157

A: $185

B: $150

C: $157

Answer:

Yes, they are equivalent.

Answer:

the answer is d add 8x to both sides

Step-by-step explanation:

The missing step in step 2 is to add 8x to both sides of the inequality.

An inequality shows the relationship between two mathematical expressions which is denoted by the inequality signs such as (<, >, ≤, ≥).

The inequality given is expressed as:

5 - 8x < 2x + 3

5 - 8x - 3 < 2x + 3 - 3

2 - 8x  < 2x

So, we need to add + 8x to both sides, in order to eradicate the variable (8x) from the left-hand side.

i.e.

2 - 8x + 8x < 2x + 8x

2 < 10x

In step 3, we divide both sides by the coefficient of x.

i.e.

Step-by-step explanation:

[tex]\frac{u}{4}[/tex] + 12 = 18

   -12    -12

[tex]4*\frac{u}{4}[/tex] = 6*4

u = 24

Answer:

u = 24

Step-by-step explanation:

Original Equation:

u/4 + 12 = 18

Subtract 12 from both sides

u/4 = 6

To separate the u from the 4, multiply both sides by 4

u = 24
