A printer toner company launches a new product. The number of pages that this new toner can print is normally distributed with a
Vitek1552 [10]

Answer:

Step-by-step explanation:

Since the number of pages that this new toner can print is normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = the number of pages.

µ = mean

σ = standard deviation

From the information given,

µ = 2300 pages

σ = 150 pages

1)

the probability that this toner can print more than 2100 pages is expressed as

P(x > 2100) = 1 - P(x ≤ 2100)

For x = 2100,

z = (2100 - 2300)/150 = - 1.33

Looking at the normal distribution table, the probability corresponding to the z score is 0.092

P(x > 2100) = 1 - 0.092 = 0.908

2) P(x < 2200)

z = (x - µ)/σ/√n

n = 10

z = (2200 - 2300)/150/√10

z = - 100/47.43 = - 2.12

Looking at the normal distribution table, the probability corresponding to the z score is 0.017

P(x < 2200) = 0.017

3) for underperforming toners, the z score corresponding to the probability value of 3%(0.03) is

- 1.88

Therefore,

- 1.88 = (x - 2300)/150

150 × - 1.88 = x - 2300

- 288 = x - 2300

x = - 288 + 2300

x = 2018

The threshold should be

x < 2018 pages

Which type of parent function is graphed on the coordinate plane?
Sophie [7]

Answer : option A

In logarithmic Parent  function, there will be a vertical asymptote.

In the given graph , there is a horizontal asymptote. The graph goes close to y axis but does not cross y axis.

The graph goes close to y axis so there is a horizontal asymptote. Its not a parent logarithmic function.

The graph of exponential function with base 0 to 1 , the y value decreases when x increases. In the given graph the y values increases when x value increases. so the base of the exponential function will be greater than 1

Option A is correct

dolphi86 [110]

A large basket of apples weighed 10 2/3lb

Basket was 1 1/4lb

Apples weigh = 10 2/3 - 1 1/4

Apples weigh = 10 8/12 - 1 3/12

Apples weigh = 9 5/12

Answer

Apples weighed 9 5/12 lbs

Answer:

True

Step-by-step explanation:

  1. 4 ÷ 7 = 0.5714
  2. 18 ÷ 31.5 = 0.5714
  3. Because they are the same result, the two fractions are equal. Therefore, the equation is true.
