The answer is the second one
Answer:
D
Step-by-step explanation:
We know that four (4) queen cards are present in the deck of 52 cards. So, the probability of drawing one queen card is calculated as,
P = 1/13
The probability of not a queen is calculated as,
P' = 1 - P = 1 - 1/13 = 12/13
We will have the following:
First, we can see that the volume of the sphere and the regular cone are given by:
And:
Now, since the volume of the cone is inscribed by a maximum stablished by the sphere, we know that the maximum height for the cone will be equal to the radius of the sphere, so, we re-write the volume of the cone:
i. Now, we determine the ratio of both volumes as follows:
[Cone to sphere]
So, the ratio of the volumes of the cone to the sphere will be of 1:4.
ii. And the expression in terms of r for the volume inside the sphere but outside the cone will be:
So, the expression is:
19) because 1/2 an hour is 8 miles, 1 hour will take 16 miles , multiply 8 by 2 because I️t gave half an hour so multiplying by 2 will give an hour (2 half’s make a whole)
20) 2 1/2 multiplied by 4 is 10, so his jog will be 10 minutes longer
21) 4,500 was what he earned and 4,900 was what he lost (“expenses”) so he lost $400:
$4,500 - $4,900= -$400
He lost money because the answer is negative
It's a little weird because area of a triangle is always 1/2 bh it doesn't ask for units
A)1/2 bh (put numbers in unit of feet)
B)asks to find area using A (like you know area in unit of square feet )( every
square feet is 144 square inch)
C)1/2*3*2.2=1.1*3=3.3 square inch
