<h3>Answer: choice B) 120</h3>

=============================

Explanation:

1 yard = 3 ft, 1 ft = 12 inches

Based on those two facts, 1 yard = 36 inches (since 3*12 = 36).

So 25 yards = 900 inches after you multiply both sides by 25.

Divide this over 22 to get 900/22 = 40.909090909091 which rounds down to 40 (see note below). One ribbon gets us 40 pieces, so 3 of them will get 3*40 = 120 which is the answer

note: Why do we round down and not up even though we're really close to 41? Because Erika doesn't have 41 full pieces. Instead, she has 40 whole pieces plus a fraction that is close to 1, but it's not completely there. So we just ignore that fractional part.

Side note: this is assuming that she does not waste any of the fabric. Also keep in mind that the scissors has its own width (however small), so this will likely add a bit of waste. Each scissor slice produces a thin bit of fabric that can't be used. To make things simple, its ideal to ignore this fact.

marin [14]

Answer:

H0 ; μ ≤ 4 pCi/L

Ha ; μ > 4 pCi/L

The null hypothesis is that the concentration of dangerous, cancer-causing radon gas in her classroom is less than or equal to the safe level of 4pCi/L

H0 ; μ ≤ 4 pCi/L

The alternative hypothesis is that the concentration of dangerous, cancer-causing radon gas in her classroom is greater than the safe level of 4pCi/L.

Ha ; μ > 4 pCi/L

Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

The null hypothesis is that the concentration of dangerous, cancer-causing radon gas in her classroom is less than or equal to the safe level of 4pCi/L

H0 ; μ ≤ 4 pCi/L

The alternative hypothesis is that the concentration of dangerous, cancer-causing radon gas in her classroom is greater than the safe level of 4pCi/L.

Ha ; μ > 4 pCi/L

Sveta_85 [38]


I would think that it would be the 3:8 one because if you do the math, 8-3 is 5 and 12-5 is 7. The only reason Im doing it this way is because its the only way I can set it up.

so you have more of a difference with the 12:5 one and less of a difference with the 3:8.

I hope I helped a bit

What is the anser to the equation 2^{2x+2} = 2^{3x}
Marianna [84]

Answer: C) x = 2

2^{2x + 2} = 2^{3x}

Since both terms (above) have the same base, set the exponents to be equal:

2x + 2 = 3x (Rearrange to solve for x)

x = 2

∴ x = 2
