Answer:
12
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
PC * PA = PB^2
(PA+AC) * PA = PB^2
(4+32) * 4 = PB^2
36*4 = PB^2
144 = PB^2
Taking the square root of each side
sqrt(144) = sqrt(PB^2)
12= PB
The probability of selecting two jelly-filled donuts in a row is 1/ 22
<h3>What is probability?</h3>
Probability is simply the chance that a given event will occur.
It is also the ratio of the number of outcomes in a set of equally likely outcomes that produce a given event to the total number of possible outcomes.
From the information given, we have that the donuts are:
- 6 are jelly-filled
- 10 are lemon-filled
- 8 are custard-filled
Note that two jelly - filled donuts were taken without replacement
Probability( 2 jelly -filled donuts) = 6 / 24 × 4/ 22 = 24/ 24 × 22 = 1/ 22
Thus, the probability of selecting two jelly-filled donuts in a row is 1/ 22

"<span>Arc cd 1\4 of the circumstance of a circle. What is the radian measure of the central angle." Better: 'The arc CD is 1/4 the circumference of a circle. What is the radian measure of the central angle?'
That would be 1/4 of 2pi, or pi/2 (answer)</span>
Answer:
<h2>700 (units
)</h2>
Step-by-step explanation:
Surface Area =2 length x width + 2 length x height + 2 height x weight
so we do:
7 x 12 = 84 84 x 2 = 168
7 x 14 = 98 98 x 2 = + 196
14 x 12 = 168 168 x 2= <u> + 336</u>
