Answer:

y = 1/2x + 7

Step-by-step explanation:

y= mx + b is written in slope- intercept form. Plug in the numbers.

you distribute 1/2 to x and to 8

y= 1/2x + 4 + 3

simplify

y= 1/2x + 7

the problem can't be anymore simplified

Suppose the weights of farmer carl's potatoes are normally distributed with a mean of 8.0 ounces and a standard deviation of 1.1
denis23 [38]
Given that <span>the weights of farmer carl's potatoes are normally distributed with a mean of 8.0 ounces and a standard deviation of 1.1 ounces.

The probability of a normally distributed data between two values (a, b) is given by:

P(a\ \textless \  X\ \textless \  b)=P\left(z\ \textless \  \frac{b-\mu}{\sigma/\sqrt{n}} \right)-P\left(z\ \textless \  \frac{a-\mu}{\sigma/\sqrt{n}} \right) \\  \\ =P(7.5\ \textless \ X\ \textless \ 8.5)=P\left(z\ \textless \  \frac{8.5-8.0}{1.1/\sqrt{6}} \right)-P\left(z\ \textless \  \frac{7.5-8.0}{1.1/\sqrt{6}} \right) \\  \\ =P(z\ \textless \ 1.113)-P(-1.113)=0.8672-0.1328=0.7344</span>

Elaina ran 2.52 miles on Monday, 4.53 miles on Wednesday, and 3.45 miles on Saturday. What percent of the total miles did Elaina
Aleks04 [339]
Add all the miles
2.52+4.53+3.45=10.5 miles

(Monday/total miles)*100%
=(2.52/10.2)= 24%

Suppose that 1% of all computers of a certain type experience CPU failure during the warranty period. If a simple random sample
Zigmanuir [339]

Answer:

A)

μ = 5

σ = 2.2

B)

P(0) = 0.0066

C)

P(x ≥ 4) = 0.74

Step-by-step explanation:

A) The expected value is going to be the same as the mean μ.

We can use the binomial probability distribution because there are a fixed number of trials (500), each trial is independent and there are only two possible outcomes (CPU failure or not) and the probability of failure has the fixed value 0.01.

For binomial distributions:

μ = np, where p is the probability (in this case of CPU failure) and n is the number of trials (500)

μ = (500)(0.01) = 5

σ = \sqrt{npq}, where q = 1 - p

σ = \sqrt{(500)(0.01)(0.99)} = 2.2

B) We can use the binomial probability formula

P(x)=(\frac{n!}{(n-x)!x!}) × pˣ × qⁿ⁻ˣ

P(0)=(\frac{500!}{(500-0)!0!}) × 0.01⁰ × 0.99⁵⁰⁰

C) In this case wee need to use a binomial distribution calculator. Setting n as 500, π = 0.01 and finding the probability above 3.

Slope of (7,1) (12,4)
Kamila [148]

Answer:

the slope is 3/5

Step-by-step explanation:

We can find the slope from two points using the formula

m = (y2-y1)/(x2-x1)

    = (4-1)/(12-7)

     = 3/5
