An electrician charges $20 for a service call plus $40 per hour of service. Write an equation in slope-intercept form for the co

Zigmanuir [339]

Answer:

Step-by-step explanation:

Regular charge- $20

Every hour of service cost- $40

Equation or slope intercept form-

C= 40h+20

Part 1- 20+40(8)=

40 multiplied by 8 320+20 = $340

Part 2- 20+40(10)=

40 multiplied by 10 400+20 = $420

PLEASE HELP I WILL MARK YOU BRAINLIEST AND PLEASE SHOW YOUR WORK.

Feliz [49]

Answer:

Part A: 7.58974359 gallons (I don't know if you needed to round so I kept the full number).

Part B: 8.871794872 gallons

Step-by-step explanation:

Part A's Steps:

First Step: 350 - 54 = 296

Second Step: 296 ÷ 39 = 7.58974359 (Round if you need to)

Part B's Steps:

First Step: 296 + 50 = 346

Second Step: 346 ÷ 50 = 8.871794872

An urn contains 8 red chips, 10 green chips, and 2 white chips. A chip is drawn and replaced, and then a second chip is drawn.

Harlamova29_29 [7]

Answer:

(A) 0.04

(B) 0.25

Step-by-step explanation:

Let R = drawing a red chips, G = drawing green chips and W = drawing white chips.

Given:

R = 8, G = 10 and W = 2.

Total number of chips = 8 + 10 + 2 = 20

$P(R) = \frac{8}{20}=\frac{2}{5}\\P(G)= \frac{10}{20}=\frac{1}{2}\\P(W)= \frac{2}{20}=\frac{1}{10}$

As the chips are replaced after drawing the probability of selecting the second chip is independent of the probability of selecting the first chip.

(A)

Compute the probability of selecting a white chip on the first and a red on the second as follows:

$P(1^{st}\ white\ chip, 2^{nd}\ red\ chip)=P(W)\times P(R)\\=\frac{1}{10}\times \frac{2}{5}\\ =\frac{1}{25} \\=0.04$

Thus, the probability of selecting a white chip on the first and a red on the second is 0.04.

(B)

Compute the probability of selecting 2 green chips:

$P(2\ Green\ chips)=P(G)\times P(G)\\=\frac{1}{2} \times\frac{1}{2}\\ =\frac{1}{4}\\ =0.25$

Thus, the probability of selecting 2 green chips is 0.25.

(C)

Compute the conditional probability of selecting a red chip given the first chip drawn was white as follows:

$P(2^{nd}\ red\ chip|1^{st}\ white\ chip)=\frac{P(2^{nd}\ red\ chip\ \cap 1^{st}\ white\ chip)}{P (1^{st}\ white\ chip)} \\=\frac{P(2^{nd}\ red\ chip)P(1^{st}\ white\ chip)}{P (1^{st}\ white\ chip)} \\= P(R)\\=\frac{2}{5}\\=0.40$

Thus, the probability of selecting a red chip given the first chip drawn was white is 0.40.
