23+24+25 Add these integers to equal 72.
Answer:
b = -36
Step-by-step explanation:
Start by distributing both th 5 and the negative 1 into their corresponding parentheses.
((5*2b)-(5*3)) > (10b - 15)
((-1*11b)+(-1*1)) > (-11b - 1)
so you have:
10b - 15 - 11b - 1 = 20
Next you would Combine like terms to get:
-b - 16 = 20
Add the 16 to both sides
-b = 36
and divide each side by -1
b = - 36

Answer:
C.
normal distribution
Step-by-step explanation:
The Sampling Distribution of the Sample Proportion. If repeated random samples of a given size n are taken from a population of values for a categorical variable, where the proportion in the category of interest is p, then the mean of all sample proportions (p-hat) is the population proportion (p)
Sample proportion would be normal with mean = p and variance = pq/n where q = 1-p and n= the sample size
The condition is that both np and nq must be greater than 10
Hence we can take that this will be normal provided np>10 or p>1/4 and q >1/4
i.e. p lies between 1/4 and 3/4
C.
normal distribution (assuming conditions are satisfied)
Monday, 2.5×2.2=5.50
Tues, 1.2×2.2=2.64
5.50+2.64=8.14
