What are the solutions to the equation: (x - 6)(x + 5) = 0?
answers
5

-5

6

-6
no joke answers or will be reported

Answers

Answer:

Step-by-step explanation:

Multiplying anything by zero equals zero. So if either term equals zero the equation is true.

(x-6)(x+5)=0

So if x=-5 or 6 the above is true.

x=(-5,6)

Answer:

the answers I found are 6 and -5

if you separate the two and equate them to 0 you will get the answers like this :

x - 6 = 0. or x + 5 = 0

x= 6. or x = -5

it’s 2boxes because there’s 10 in each line , with 8 rows 8x2 equals 160 which is closest to 140 .









Hi there!

[tex]\large\boxed{3 \text{ boxes}}[/tex]

Calculate the number of boxes of cubes needed by calculating the volume of the pictured figure.

We can see that it has a width of 4 blocks, depth of 2 blocks, and a height of 8 blocks.

Calculate volume: V = l × w × h

V = 4 × 2 × 8  = 64 cubes in each box.

Since she needs 140 cubes, we can find how many boxes she would need for this amount:

140 ÷ 64 = 2.1875.

However, you cannot buy a part of a box, which is why you must round to a whole number. However, only buying 2 boxes would be too little.

Thus, she would need to buy 3 boxes.

A baseball player throws a ball from second base to home plate. How far does the player throw the ball? Include a diagram showing how you got your answer. Decide how many decimal points of accuracy are reasonable. Explain your reasoning.

Answers

Answer:

Distance=123.28. Two decimal places is reasonable, because it gives a close approximate to the exact answer, while remaining short and easy to use.

Step-by-step explanation:

Use Pythagorean theorem.

90^2+90^2=c^2

In order to determine whether or not there is a significant difference between the mean hourly wages paid by two companies (of the same industry), the following data have been accumulated.

Company A Company B
Sample size 80 60
Sample mean $16.75 $16.25

Population standard deviation $1.00 $.95 The p-value is:_________

a. 0.0084.
b. 0.0042.
c. 0.0026.
d. 0.0013

Answers

Answer:

The p-value is;

d. 0.00131

Step-by-step explanation:

The given question parameters are;

                                                     Company A   [tex]{}[/tex]                       Company B

Sample size                                   80[tex]{}[/tex]                                         60

Sample mean   [tex]{}[/tex]                            [tex]\overline x_1[/tex] $16.75                            [tex]\overline x_2[/tex] $16.25

Population standard deviation [tex]{}[/tex]   σ₁  $1.00                           σ₂ $0.95

[tex]z=\dfrac{(\bar{x}_{1}-\bar{x}_{2})-(\mu_{1}-\mu _{2} )}{\sqrt{\dfrac{\sigma_{1}^{2} }{n_{1}}+\dfrac{\sigma _{2}^{2}}{n_{2}}}}[/tex]

Therefor, we have;

[tex]z=\dfrac{(16.75-16.25)-(0-0)}{\sqrt{\dfrac{1^{2} }{80}+\dfrac{0.95^{2}}{60}}} \approx 3.0128[/tex]

The p-value = 1 - 0.99869 (the area to the right of 3.01) = 0.00131
