Answer:

1/2

Step-by-step explanation:

It is a independent problem. Flipping a head the first time will not affect the other results therefore it is still one half.

What value of x in the solution set of 2x-3 is greater than 11-5×

Salsk061 [2.6K]

Answer:

the value of x if that's what you mean is 2 because first you add 3 from both sides and your new equation should be 2x>14-5×, then you add 5x from both sides and your new equation should be 7x>14. After that you divide 14 by 7 and your final answer will be x=2 or 2

1.a telephone company is asked to provide service to a customer whose house is located in the forest, 900 feet away from the roa

adelina 88 [10]

In total, the cost to install the phone line for the customer in the forest will be $31,500+$84,000=$115,500.

<h3>What is meant by addition?</h3>

Combining two or more numbers or quantities to generate a sum is known as addition in mathematics. One of the four fundamental operations of arithmetic, along with addition, subtraction, multiplication, and division, it is often denoted by the sign "+."

Addition is a key concept that is taught to children at an early age and is utilised in a number of everyday settings such as shopping and banking. It is a crucial tool for tackling increasingly difficult issues in disciplines like engineering, physics, and finance. For example, a telephone company is asked to provide service to a customer whose house is located in the forest, 900 feet away from the road along

Mental computation, pencil and paper, and calculators are only a few of the techniques that may be used to do addition. First, arrange the digits in columns, starting with the ones place, before adding two numbers.

How to solve?

To provide service to the customer in the forest, the telephone company will have to run a phone line 900 feet through the forest at a cost of $35 per foot, for a total cost of 900*$35=$31,500.

Additionally, the company will have to run the line 4,200 feet down the road at a cost of $20 per foot, for a total cost of 4,200*$20=$84,000.

In total, the cost to install the phone line for the customer in the forest will be $31,500+$84,000=$115,500.

A manufacturer of running shoes knows that the average lifetime for a particular model of shoes is 15 months. Someone in the res

AveGali [126]

Answer:

The decision rule is

Fail to reject the null hypothesis

The conclusion is

There is no sufficient evidence to show that the designer's claim of a better shoe is supported by the trial results.

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 15 \ months$

The sample size is n = 25

The sample mean is $\= x = 17 \ months$

The standard deviation is $s = 5.5 \ months$

Let assume the level of significance of this test is $\alpha = 0.05$

The null hypothesis is $H_o : \mu = 15$

The alternative hypothesis is $H_a : \mu > 17$

Generally the degree of freedom is mathematically represented as

$df = n -1$

=> $df = 25 -1$

=> $df = 24$

Generally the test statistics is mathematically represented as

$t = \frac{\= x- \mu }{\frac{s}{\sqrt{n} } }$

=> $t = \frac{ 17 - 15 }{\frac{5.5}{\sqrt{25} } }$

=> $t = 1.8182$

Generally from the student t distribution table the probability of obtaining $t = 1.8182$ to the right of the curve at a degree of freedom of $df = 24$ is

$p-value = P(t > 0.18182 ) = 0.4286$

From the value obtained we see that $p-value > \alpha$ hence

The decision rule is

Fail to reject the null hypothesis

The conclusion is

There is no sufficient evidence to show that the designer's claim of a better shoe is supported by the trial results.
