Step by step. :)

STEP
1
:
Equation at the end of step 1
0 - 7n • (n - 7) = 0
STEP
2
:
Equation at the end of step 2
-7n • (n - 7) = 0
STEP
3
:
Theory - Roots of a product
3.1    A product of several terms equals zero.    When a product of two or more terms equals zero, then at least one of the terms must be zero.    We shall now solve each term = 0 separately    In other words, we are going to solve as many equations as there are terms in the product    Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2      Solve  :    -7n = 0    Multiply both sides of the equation by (-1) : 7n = 0

Divide both sides of the equation by 7:
                     n = 0
Solving a Single Variable Equation:
3.3      Solve  :    n-7 = 0    Add 7 to both sides of the equation :                        n = 7

This is what i got! if i’m wrong i’m so sorry
but i tried. have a amazing day☺️☺️

Assuming the probability of a single sample testing positive is 0.15, find the probability of a positive result for two samples

Grace [21]

Answer:

$P(Positive\ Mixture) = 0.2775$

The probability is not low

Step-by-step explanation:

Given

$P(Single\ Positive) = 0.15$

$n = 2$

Required

$P(Positive\ Mixture)$

First, we calculate the probability of single negative using the complement rule

$P(Single\ Negative) = 1 - P(Single\ Positive)$

$P(Single\ Negative) = 1 - 0.15$

$P(Single\ Negative) = 0.85$

$P(Positive\ Mixture)$ is calculated using:

$P(Positive\ Mixture) = 1 - P(All\ Negative)$ ---- i.e. complement rule

So, we have:

$P(Positive\ Mixture) = 1 - 0.85^2$

$P(Positive\ Mixture) = 1 - 0.7225$

$P(Positive\ Mixture) = 0.2775$

<em>Probabilities less than 0.05 are considered low.</em>

<em>So, we can consider that the probability is not low because 0.2775 > 0.05</em>

A car travels for 3 hours and covers 156 miles. Find the average speed of the car.

lidiya [134]

Answer:

52 miles per hour

Step-by-step explanation:

Firstly, It is important to point out that it is Average speed. The Average speed throughout all the way the car traveled.

And this is may calculated by a simple formula or if you'd rather by a proportion. Let's pick this simple formula, what's going to be useful.

Let's do the math!

Average speed = Δs/Δt

Δs = Variation of Space (given in miles) =156 -0

Δt =Variation of Time (given in hours) =3-0

Average Speed = 156-0/3-0 =156/3 =52 miles per hour

It is important to say, Average speed, is a rate so it is given in miles per hour

Find the value of x to the nearest tenth. *

Alla [95]

Answer:

x ≈ 61.8

Step-by-step explanation:

Using the sine ratio in the right triangle

sin15° = $\frac{opposite}{hypotenuse}$ = $\frac{16}{x}$ ( multiply both sides by x )

x × sin15° = 16 ( divide both sides by sin15° )

x = $\frac{16}{sin15}$ ≈ 61.8 ( to the nearest tenth )
