Answer:

Yes, Sierra is correct

Step-by-step explanation:

Given

4(y + 7) > -3 (4 + 5)

Required

Is she correct

The right parenthesis has 4 + 5.

This can be simplified as: 4 + 5 = 9

So, we have:

4(y + 7) > -3 (4 + 5)

4(y + 7) > -3 *9

The left parenthesis has y + 7.

This cannot be simplified because y is a variable and 7 is a number.

<em>Hence, Sierra is correct.</em>

The lifetimes of 10,000 watch batteries are normally distributed the mean lifetime is 500 days the standard deviation is 60 days
Lelu [443]
Given:
μ = 500 days, the population mean
σ = 60 days, the population standard deviation

Therefore
μ + σ = 560
μ - σ = 440
μ + 2σ = 620
μ - 2σ = 380
μ + 3σ = 680
μ - 3σ = 320

The figure shown below illustrates the normal distribution
About 68% of the total area lies in x = (μ-σ, μ+σ)
About 95% of the total area lies in x = (μ-2σ, μ+2σ)
About 99.7% of the total area lies in x = (μ-3σ, μ+3σ).

What is the greatest common factor (GCF) of the numerator and denominator
ad-work [718]

Answer:

C

Step-by-step explanation:

x²+2x-15 = x²-3x+5x-15 = x(x-3)+5(x-3)=(x+5)(x-3)

or delta:

∆=2²-4*1*(-15)=4+60=64

√∆=8

x1 = (-2+8)/2 = 3

x2=(-2-8)/2=-5

and 4x+20 = 4(x+5)

The same is (x+5), so it is GCF. answer C
