Answer:

C, none of the above

Step-by-step explanation:

-4(3d-2) after expression should be -12d+8 and then add -7, so combine like terms would be -12d+1, which is not the choice, so the answer is none of the above.

Answer:

4000grams in each bag

Step-by-step explanation:

Assume he put x amount of clay into each bag, he then put 6x into 6 bags.(since the question didn’t mention, I assume he put every clay he has into the bags)

6x=24kg

x=4kg

Since the question is asking for grams not kilograms:

4kg=4000g

Step-by-step explanation:

Answer:

The required amount of paper is 2715.23 [tex]cm^{2}[/tex].

Step-by-step explanation:

The cans of soup has a shape of a cylinder, so that;

The surface area around a cylinder = 2[tex]\pi[/tex]rh

Where: r is the radius of the can, and h is its height.

From the given question, diameter = 8 cm, then;

radius = [tex]\frac{diameter}{2}[/tex]

          = [tex]\frac{8}{2}[/tex]

r  = 4 cm

Surface area around one of the cans = 2 x [tex]\frac{22}{7}[/tex] x 4 x 9

                                                = 226.2857

Surface area around one of the cans = 226.28 [tex]cm^{2}[/tex]

So that, the total amount of paper required to make labels around each of the 12 cans can be determined by:

12 x 226.2857 = 2715.4284

The required amount of paper is 2715.23 [tex]cm^{2}[/tex].

80°+20°+missing angle=180°[ sum of interior angle of a triangle is 180°]

missing angle=180°+100=80°

is your answer

Answer: i think i got b or c onr of them are correct  :)

Step-by-step explanation:

The estimated population mean with

80% confidence =  [30.856, 33.135]

90% confidence = [30.543, 33.456]

98% confidence =  [29.94, 34.06]

For a population with unknown mean  and known standard deviation , a confidence interval for the population mean, based on a simple random sample of size n, is [tex]\bar x +_{-}z^{*}\frac{\sigma}{\sqrt{n} }[/tex] , where z* is the upper (1-C)/2 critical value for the standard normal distribution.

Population standard deviation = 5.6

Sample mean = 32

Sample size = 40

Given confidence level = 80%

[tex]z^{*}[/tex] at 80% confidence level = 1.28

Upper confidence interval = 33.135

Lower confidence interval = 30.865

Population mean lies between [30.856, 33.135] at 80% confidence level.

Given confidence level = 90%

[tex]z^{*}[/tex] at 90% confidence level = 1.65

Upper confidence interval =33.456

Lower confidence interval = 30.543

Population mean lies between [30.543, 33.456] at 90% confidence level.

Given confidence level = 98%

[tex]z^{*}[/tex] at 98% confidence level = 1.65

Upper confidence interval = 34.06

Lower confidence interval = 29.94

Population mean lies between [29.94, 34.06] at 98% confidence level.

Answer:

yes

Step-by-step explanation:

see attached graph - there are two real roots for y=2x^4-6x^2+10x-7

so 2x^4-6x^2+10x-7 can be expressed as:

(x - root1)(x - root2)(2x^2+Bx+C)

Answer:

Yes, it can be.

Step-by-step explanation:

Using solver program, the expression 2x^4-6x^2+10x-7 has:

two real roots at x≈-2.3888 and x≈1.1424

and

two complex roots at x≈0.62321 - 0.94559 i and x≈0.62321 + 0.94559 i

Because it has two real roots, the expression can be simplified.
