Since one nickel equals 5 cents, you'd multiply 10 nickels by 5 cents apiece and yield 50 cents to spend.
Answer:
the answer is 64
Step-by-step explanation:
Answer:16
Step-by-step explanation:
Let the number be X
Twice the sum of a number and 5
= 2X+5
Three times the difference of the number and 2
= 3(X - 2)
Since Twice the sum of X and 5 is equal to three times the difference of the X and 2, This means
2(X + 5 )= 3(X - 2)
2X +10 = 3X - 6
3X -2X = 10 + 6 = 16
X = 16
Check
2×(16+5) =3×(16-2)
2×21 = 3×14
42 = 42
Answer: 0.022
Step-by-step explanation:
Let p be the population proportion of horses were fed mostly alfalfa.
We are given that :
, since alternative hypothesis (
) is right tailed , so the test is a right-tailed test.
Also, we have
Sample size= 62
Sample proportion= 
Test statistic for population proportion:-
Substitute all values ,
P-value for right tailed test :
P(z>2.01)=1-P(z<2.01) [∵P(Z>z=1-P(Z<z))]
=1-0.9777844 [By using z-value table]
=0.0222156≈0.022
Hence, the P-value for this test is <u>0.022</u> .
