A) three numbers sum to 15. The mode of the three numbers is 1. What must the three number be?

1 answer:

6 0

The mode is a number that is repeated the most, so if there is 3 numbers, the "mode number" has to be repeated twice or three times.

A) since 1 is the mode, two of the numbers are 1, the last number is
15 -1 -1 = 13  the three numbers are 1, 1, and 13.

B) since 5 is the mode, two of the numbers are 5, the last number is
11 -5 -5 = 1 the three numbers are 5, 5, and 1.

Range is when you subtract the smallest number to the biggest number, so 5-1=4 The answer is 4

Please helpppp it has to do with P(A U B)

Katyanochek1 [597]

$P(A)=0.5$ , $P(B)=0.6$ , $P(A\cup B)=0.8$

We find the probability of intersection using the inclusion/exclusion principle:

$P(A\cap B)=P(A)+P(B)-P(A\cup B)=0.3$

By definition of conditional probability,

$P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}=\dfrac{0.3}{0.6}=0.5$

For $A$ and $B$ to be independent, we must have

$P(A\cap B)=P(A)\cdot P(B)$

in which case we have $0.3=0.5\cdot0.6$ , which is true, so $A$ and $B$ are indeed independent.

Or, to establish independence another way, in terms of conditional probability, we must have

$P(A\mid B)\cdot P(B)=P(A)\cdot P(B)\implies P(A\mid B)=P(A)$

which is also true.

a corner shelf is 1/4 of a circle and has a radius of 10.5 inches . Enter the area of the shelf in square inches . round your an

schepotkina [342]

First, find the area of the shelf if it were a full circle.
the formula for the area of a circle is a=pi(r squared)
a=pi (10.5 squared)
a=pi x 110.25
a=3.14 x 110.25
a=346.185
now, you have to divide that area by 4 to get the area of the 1/4 circle
346.185/4=86.55
