Y=-6x+.75
Due to first you will have to subtract 3x from both sides then divide by 4 from both sides which will equal a slope of -6 and a y-intercept of .75 or three fourths

Rearrange so 4y= -3x-24 then divide everything by 4so,

Y=-3x/4 - 6. The intercept is -6

Part A. Express the original claim in symbolic form.

Claim: The mean pulse rate (in beats per minute) of adult males is equal to 68.9 bpm.

Therefore, the original claim in symbolic form is:

ANSWER:

$\mu=68.9\text{ bpm}$

Part B. Identify the null and alternative hypotheses.

$\begin{gathered} H_0\colon\text{ }\mu=68.9\text{ bpm} \\ H_1\colon\mu\ne68.9\text{ bpm} \end{gathered}$ $\begin{gathered} H_0\text{ or the null hypothesis will be based to our claim. We will test if the mean pulse} \\ \text{rate of an adult male is equal to 68.9 bpm.} \\ H_1\text{ or the alternative hypothesis is the one that contradicts the null hypothesis. That is } \\ \text{why our H}_a\text{ has the sign of not equal to (}\ne). \end{gathered}$

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 5.8 years, and standard deviation of

fenix001 [56]

Answer:

3.6 years

Step-by-step explanation:

Using the standard normal probability distribution table, we obtain the Zscore which is 10% to left of the distribution.

The Zscore gives, - 1.282

To obtain the number of years, let this be x ;

Recall, the Zscore formula :

Zscore = (x - μ) / σ

x = number of years

μ = 5.8

σ = 1.7

Zscore = (x - μ) / σ

-1.282 = (x - 5.8) / 1.7

-1.282 * 1.7 = x - 5.8

-2.1794 = x - 5.8

-2.1794 + 5.8 = x

x = 3.6206

x = 3.6 years

(6,8),(-1,12)the two given points are connected to form the diagonal of a rectangle. Find the perimeter of the rectangle

vampirchik [111]

Answer:

Step-by-step explanation:

The problem can be solved geometrically. By this way, the solution is going to be easy, as well.

We can see from the attached graph that the coordinates are the vertexes.

Considering a unit distance, we can find that the width of this rectangle is:

4 = 12 - 8

and the length is:

7 = 6-(-1)

Then, the perimeter is P = (4+7)*2 = 22
