24.56m. your problem should look like a^2+29^2=38^2. you the. have a^2+841=1444. you subtract 841 from 1444 and are left with 603. < this is a^2. you take the square root of that and get 24.56
5x+12z Because you take, 3z+9z and that is equivalent to 12z. and then you put the 5x back into the equation so it is 5x+12z
Answer: b. H0: μ ≥ 5; Ha: μ < 5
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 mean is 5 years and they claim it will perform for more than 5 years.
Therefore, for the case above;
H0: μ ≥ 5; Ha: μ < 5
Note: a null hypothesis must always include an equal to sign.
Rectangle on the left = 3 × 4 = 12
Rectangle in the middle = 3 × 2 = 6
Rectangle on the right = 4 × 3 = 12
Add:
12 + 6 + 12 = 30
Answer = 30
Hope this helped☺☺
