Find the smallest integer that satisfies the inequalities

sammy [17]

Answer:

a. x> 23 /3

b: x< 13/5

Step-by-step explanation:

A: Step 1: Subtract x from both sides.

4x−15−x>x+8−x

3x−15>8

Step 2: Add 15 to both sides.

3x−15+15>8+15

3x>23

Step 3: Divide both sides by 3.

<u>x> 23/3</u>

B: Step 1: Subtract 7x from both sides.

2x+13−7x>7x−7x

−5x+13>0

Step 2: Subtract 13 from both sides.

−5x+13−13>0−13

−5x>−13

Step 3: Divide both sides by -5.

Answer: x< 13/5

Substitute for y=4x-1;y=2x-5

konstantin123 [22]

<span>y=4x−1;y=2x−5
Step: Solve y=4x−1 for y:
Step: Substitute 4x−1 for y in y=2x−5:
y=2x−5
4x−1=2x−5
4x−1+−2x=2x−5+−2x(Add -2x to both sides)
2x−1=−5
2x−1+1=−5+1(Add 1 to both sides)
2x=−4
2x/2=−4/2(Divide both sides by 2)
x=−2
Step: Substitute−2 for x in y=4x−1:
y=4x−1
y=(4)(−2)−1
y=−9(Simplify both sides of the equation)
<u>Answer:</u>y=−9 and x=−2</span>

What is the domain of the function y=-720t + 3600 ?

Colt1911 [192]

Answer:

We conclude that:

$\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

Please also check the attached graph.

Step-by-step explanation:

Given

Given the function

$y=-720t\:+\:3600$

To determine

What is the domain of the function y=-720t + 3600

We know that the domain of the function is the set of input argument values for which the function is real and defined.

Given the function

$y=-720t\:+\:3600$

From the given function, it is clear that the function has no undefined points nor domain constraints.

Therefore, the domain of the function is

$-\infty \:$

Thus, we conclude that:

$\mathrm{Domain\:of\:}\:-720t+3600\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:$

Customers are used to evaluate preliminary product designs. In the past, 95% of highly successful products received good reviews

maks197457 [2]

Answer:

Step-by-step explanation:

The given information can be tabulated as follows.

Success type High Moderate Low Total

0.40 0.35 0.25 1

Good reviews 0.95 0.60 0.10

Combined prob 0.4*0.95 0.35*0.6 0.25*0.1

0.38 0.21 0.025 0.6125

A) the probability that a product attains a good review

=Prob it it successful and gets good review + Prob it is moderate successful and gets good review +Prob it it low successful and gets good review

= 0.6125

B) If a new design attains a good review, the probability that it will be a highly successful product= $\frac{0.38}{0.6125} \\=0.6204$

C) Prob that does not attain a good review =(0.40*0.05)+0.35(0.4) +(0.25)*0.9

= 0.385

Prob for successful not getting good review = 0.40(0.05) = 0.02

Reqd prob = $\frac{0.02}{0.385} \\=0.05195$
