Answer:
50%
Step-by-step explanation:
Let :
Winter = W
Summer = S
P(W) = 0.85
P(S) = 0.65
Recall:
P(W u S) = p(W) + p(S) - p(W n S)
Since, none of them did not like both seasons, P(W u S) = 1
Hence,
1 = 0.85 + 0.65 - p(both)
p(both) = 0.85 + 0.65 - 1
p(both) = 1.50 - 1
p(both) = 0.5
Hence percentage who like both = 0.5 * 100% = 50%
Answer:
standard deviation
Step-by-step explanation:
The standard deviation is defined as the measure of how spread out the numbers are in a given population. In other words, statistics refers to the amount of the dispersion or variation of a set of given values.
It is denoted by the Greek letter sigma, σ.
Thus the standard deviation is the measure of how dispersed the data are in the population which can be used to provide context to a larger data sets.
First find the area of the pizza:
area = PI x r^2
diameter = 16 inches...radius = 16 /2 =8 inches
area = 3.14 x 8^2 = 3.14 x 64 = 200.96 sq inches. Round to 201 square inches
the pizza has 6 calories per square inch so now multiple the total square inches by 6 to get total calories:
201 * 6 = 1206 total calories
now divide total calories by 144 to find the number of slices:
1206 / 144 = 8.375 so the pizza can be cut into 8 slices and each slice would have a little over 144 calories
Answer:
$933.3
Step-by-step explanation:
Given data
Principal= $900
Rate= 7.55%
Time= 180 days>>> 6months>>> 0.5 years
Say the account is on a compound interest plan
A= P(1+r)^t
substitute
A= 900(1+0.0755)^0.5
A= 900(1.0755)^0.5
A= 900*1.037
A= $933.3
Hence the teacher will withdraw $933.3 on a compound interest investment after 6 months
Answer:
The answer is 26 sweaters
Step-by-step explanation:
Divide the total number of sweaters by the number of boxes. So 312 divided by 12 to get 26.
