Delta makes 12-volt car batteries. These batteries are known to be normally
blondinia [14]

Answer:

The probability that Delta car batteries last between three and four years

P(36≤X≤48) = 0.5188

The percentage of that Delta car batteries last between three and four years

P(3≤X≤4) = 52%

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the sample size n =12 -volt car batteries</em>

<em>Let  'X' be a Random variable in a normal distribution</em>

<em>Given that mean of the normal distribution = 45 months</em>

<em>Given that the Standard deviation of the normal distribution = 8months</em>

<u><em>Step(ii):-</em></u>

Let  X₁ = 3 years = 12 × 3 = 36 months

Z_{1} = \frac{x_{1} -mean}{S.D} = \frac{36-45}{8} = -1.125

Let X₂ = 4 years  = 12 × 4 = 48 months

Z_{2} = \frac{x_{2} -mean}{S.D} = \frac{48-45}{8} = 0.375

<u><em>Step(iii)</em></u>:-

The probability that Delta car batteries last between three and four years

P(36≤X≤48) = P(-1.125≤Z≤0.375)

                   = P(Z≤0.375) - P(Z≤-1.125)

                   = 0.5 +A(0.375) - (0.5-A(1.125)

                   = 0.5 + 0.1480 - (0.5 -0.3708)

                  = 0.1480 + 0.3708

                 = 0.5188

<u><em>Final answer:-</em></u>

The probability that Delta car batteries last between three and four years

P(36≤X≤48) = 0.5188

The percentage of that Delta car batteries last between three and four years

P(3≤X≤4) = 52%

Help for 13-15 pls and explain for 15
Pani-rosa [81]
13. 1
14. 1
15. any number and 0 will have a quotient of 0.
for example 7/0=0 .     8/0=0 .    9/0=0
if you try and check your work using multiplication 7*0=0 .    8*0=0 .    9*0=0
then you will realize the rule is right

Write the equation of a line in standard form that has x-intercept (P,0) and y-intercept (0,R).
ExtremeBDS [4]

Answer:

Rx+Py=RP

Step-by-step explanation:

The points on the straight line are (P, 0) and (0, R).

The slope would be

m=\frac{R-0}{0-P}=-\frac{R}{P}

And b=R, because the y-intercept is at (0, R).

So, the equation of this line would be

y=-\frac{R}{P} x+R

Where we multiply the equation by P

Py=-Rx+RP

Therefore, the equation that represents this line is

Rx+Py=RP

<h2>So, the right answer is B.</h2>
