Answer:
32
Step-by-step explanation:
The number to the right of the decimal is higher than 5, meaning you would round up.
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
Answer:
<em>The actual length of the living room is 24 feet.</em>
Step-by-step explanation:
<u>Scaling</u>
The scaling on a blueprint for an apartment is:
1 inch = 4 feet
This means every 1 inch measured on the blueprint corresponds to 4 feet on the real length of the apartment.
We know the length of the living room in the blueprint is 6 inches, thus the real dimension of the living rooms is:
6 * 4 = 24 feet
The actual length of the living room is 24 feet.
Answer: -8y+12
Step-by-step explanation: Multiply using the distributive property.
Hope this helps.
then the angle formed would be equal to 180 degree
