Answers

Answer 1

Answer:

x = 12, z = 109

Step-by-step explanation:

12x - 73 = 71

12x = 71 + 73 = 144

x = 144/12 = 12

z = 180 - 71 = 109

tori has to place one more x on the line plot for the eighth month then the total length in hours of all the calls for the eighth month will be 6 hours what is the length in hours of tori's phone calls for just eight months.
Talks 1hr month 9
Talks 1 1/2 hrs 10 and. 11th month
Ta;ks. 3/4 hr 12th month

Answers

Line plots are used to express variables using markers

The total phone call for eight months is [tex]10\frac 34[/tex] hours

How to determine the total phone calls

From the line plot, we have the following summation

[tex]Total = 1hr + 1\frac 12 hr * 2 + \frac 34 hr[/tex]

When the total hours of phone call for the 8th month is added, the summation equation becomes

[tex]Total = 1hr + 1\frac 12 hr * 2+ \frac 34 hr + 6 hr[/tex]

Add the expressions

[tex]Total = 10\frac 34[/tex]

Hence, the total phone call for eight months is [tex]10\frac 34[/tex] hours

A manufacturing corporation make tires with a probability 0.79 of lasting over 3,000 miles. What is the probability of exactly seven out of the next eight tires lasting over 3,000 miles?
(Round your answer to three decimal places.)

Answers

Answer:

A manufacturing corporation make tires with a probability 0.77 of lasting over 3,000 miles.

Step-by-step explanation:

The probability of exactly seven out of the next eight tires lasting over 3,000 miles will be 0.32.

How to find that a given condition can be modelled by binomial distribution?

Binomial distributions consist of n independent Bernoulli trials.

Bernoulli's trials are those trials which end up randomly either on success (with probability p) or on failures (with probability 1- p = q (say))

The probability that out of n trials, there'd be x successes is given by

[tex]\rm P(X =x) = \: ^nC_x \ p^x(1-p)^{n-x}[/tex]

A manufacturing corporation make tires with a probability 0.79 of lasting over 3,000 miles.

The probability of exactly seven out of the next eight tires lasting over 3,000 miles will be

P(x = 7) = ⁸C₇ (0.79)⁷ (1 – 0.79)⁽⁸⁻⁷⁾

P(x = 7) = 0.32

A deck is shaped like a parallelogram with a base length of 27 feet and a height of 11 feet. A can of wood stain will cover 40 square feet.

How many cans of stain will be needed to stain the deck?

Enter your answer in the box.

Answers

From the area of the parallelogram, it is found that 8 cans of stain will be needed to stain the deck.

What is the area of a parallelogram?

The area of a parallelogram of base length l and height h is given by:

A = lh

In this problem, the dimensions are l = 27, h = 11.

Hence, the area, in square feet, is given by:

A = 27(11) = 297.

Each can cover 40 square feet. How many cans are needed for 297 square feet?

in order for students to have a club at school they need a minimum of 26 students. If there are 19
students signed up for the club, how many more students does the club need?
What are the solutions? Select the correct choice below and fill in the answer box to complete your
choice

Answers

Answer:

7 more students.

Basic subtraction:

needed students: minimum required students - students signed up

needed students: 26 - 19

needed students: 7 students, the club needs.

Solution:

We know that the inequality form is x ≥ 26. If we subtract the number of students required by the number of students joined, we will obtain the required students to start the club.

=> Required students - Students joined = Students remained to join=> 26 - 19 = Students remained to join=> 7 students

Hence, the club needs 7 more students to have a club.

what are the solutions to this polynominal when s(x) =0 s(x) (3x^2 + 17x+10 )(x-7)(4x-3) enter your answers in the boxes, from least to greatest.

Answers

Answer:

-5, -2/3, 3/4, 7

Step-by-step explanation:

The solutions are solutions of one of the following:

(3x^2 + 17x + 10) = 0, x - 7 = 0, 4x - 3 = 0

The latter two are straightforward: x = 7 or 3/4.

To factor the first, note it must be of the form (3x + __) (x + __)

Check the pairs (10, 1) (1, 10) (5, 2) and (2, 5) and we find:

(3x + 2) (x + 5) = 0

So, we also have solutions -5, -2/3

Three workers are digging a ditch. They take turns working, and every one of them works for as long as it would take the other two to dig half of the ditch. They finished digging the ditch working in this manner. How many times faster would the three workers have finished digging the ditch if they had all been working at the same time?

Answers

The work would be finished 2.25 times faster if they had been doing the work at the same time.

Rate of doing work

Assumption;

Provided each one of the workers works for an hour which is equivalent to the time it takes to finish half of the ditch.

In essence, the total time required to finish the ditch by 2 workers is; 2 hours.

Hence, for 3 workers working simultaneously, the time required is 1hour 20 minutes. = 80 minutes

However, since they took 1 hour turns on the job, it follows that; The total time used is;

Total time = 3 × 1hr = 3 hours = 180 hours

Hence they could have finished the work in;

R = 180/80 times faster = 2.25 times faster.
