Answer:

Claim cannot be rejected

Step-by-step explanation:

We solve this by using hypothesis testing

H0: mean = 40

H1: mean ≠ 40

We have samples of 30, but we were not gives the population standard deviation. We used the t distribution

T score = 39.2-40/(7.5/√30)

= -0.5842

Degree of freedom = 30-1 = 29

Then p value = 0.5636

In conclusion, we fail to reject the null hypothesis since 0.5636 > 0.01 significance level.

So company's claim cannot be rejected

Answer:

Slope with Y intercepts and going down/ up from there

Step-by-step explanation:

I dont have graph paper, but the B part is Y intercept. That Means that the 2nd number is where the line intercepts with Y axis. The Y axis for  1 is Y=-1, with no slope meaning its a straight line with no slope. It just goes through -1 on Y axis horizontally. On number one for the second equation, 2 is the Y intercept for the other line, and the line has a rise and run of 3/1, meaning it goes up 3 on the positive side of the x axis, and it goes to the side one. Hope this made a little sense. I learned this a few weeks ago in my algebra class.

Answer:

6/5

Step-by-step explanation:

Remember:  to divide a number by a fraction, invert the fraction and multiply.

Here "the number" is 4/5 and you want to divide it by 2/3.  Invert the '2/3', obtaining 3/2, and then multiply the '4/5" by '3/2":

12/10 = 6/5 (answer)

Answer:

n=11

Step-by-step explanation:

By inspection,we see that an output is obtained by subtracting 3 from an input and the next consecutive output will follow a pattern of a difference of odd numbers that is 9+5=14

so n=14 and 14-3=11

Answer:

not sure if this is correct but is it 3??

Step-by-step explanation:

Answer:

The zero is x = 3/2 = 1.5

Step-by-step explanation:

We recognize that the trinomial  4 x^2 - 12 x + 9 is a perfect square trinomial, which comes from the following squared binomial:

(2 x - 3)^2

Therefore, the zeros are the x-values that verify the following:

(2 x - 3)^2= 0

that is   (2 x - 3) = 0 and solving for "x":

2 x = 3

x = 3 / 2

x = 1.5

Answer:

84

Step-by-step explanation:

You need to figure out 7 times what gets you 42

6 x 7 = 42

then you do the same for 14

14 x 6 = 84

sorry if this wasn't a good explanation

Step-by-step explanation:

The x and y-values in the 3rd quadrant are both negative.

Remember this:

1st quadrant- x= + y= +

2nd quadrant- x= - y= +

3rd quadrant- x= - y= -

4th quadrant- x= + y= -

Step-by-step explanation:

Answer:

X∈[tex]\frac{5}{63}, -\frac{23}{63}[/tex]

Step-by-step explanation:

Step-by-step explanation:

180° = m<A + m<B + m<C

180° = 45° +60° + m<C

180° = 105° + m<C

m<C = 180° - 105 °

m<C = 75°

Answer:

A = 16010.32

Step-by-step explanation:

Given that,

[tex]A=P(1+\dfrac{r}{k})^n[/tex]

Put P = 10,000, r = 0.08, k = 2 and n = 12 in the above formula to find A.

[tex]A=10,000(1+\dfrac{0.08}{2})^{12}\\\\=10,000\times (1.04)^{12}\\\\=16,010.32[/tex]

So, the value of A is 16010.32. Hence, the correct option is (B).

the answer to your problem is 60=x

Answer: 6.11

Step-by-step explanation:

Step 1: Multiply the whole number by the denominator:

6 × 9 = 54

Step 2: Add the product you got in Step 1 to the numerator:

54 + 1 = 55

Step 3: Divide the sum from Step 2 by the denominator:

55 ÷ 9 = 6.111111

That's it folks! The answer to 6 1/9 in decimal form is displayed below:

6 1/9 ≈ 6.11

Answer b.

Hope this answer helps you

Answer: b 6 1/9 = 6.11

Step-by-step explanation: what I did first was figure out the decimal version of 1.9 which equaled to 0.11111 etc. then due to it having a zero in front of it, you just place the in that spot making the answer 6.1111111 :)

hope this helped!

Answer:

Step-by-step explanation:

-14 - 73 i

Answer:

-28i^2-73i-42

Step-by-step explanation:

(−7)(6)+(−7)(7i)+(−4x)(6)+(−4i)(7i)

= −42−49i−24i−28i^2

= -28i^2-73i-42

Answer:

$0.36

Step-by-step explanation:

12*3       36

____ =____

100      100

p= 2

Step-by-step explanation:

1. subtract 3 from 3 and 9

2. subract 5p from 8p and 5p

3. it is now 3p = 6

4 divide both sides by 3

5. 6/3 is 2 so 2 =p

the answer will be 2.5 hope that helps you

Answer:

y = [tex]\frac{5}{-6}[/tex]x + 2

Step-by-step explanation:

Given coordinates: (6,-3) (0,2)

y = mx + b

y = mx + 2

[tex]\frac{2+3}{0-6}[/tex] = [tex]\frac{5}{-6}[/tex]

y = [tex]\frac{5}{-6}[/tex]x + 2

Answer:

Wouldn't it be 8?

Step-by-step explanation:

You crack 2 eggs and cook them, then eat them. If we cracked 2 eggs, cooked 2 different eggs, and ate 2 different eggs, that doesn't make sense.

Answer:

8

Step-by-step explanation: you can crack, cook, and eat with 1 egg

so if you cracked 2 cooked 2 and ate 2, it means that you only used 2
