I NEED HELP PLEASE ! :)

dedylja [7]

We can write a proportion to resemble the problem;

AE/ED = AB/BC

AE = 9

ED = 6

AB = x

BC = 10

Substitute with the given values.

9/6 = x/10

9/6 * 10 = x/10 * 10

90/6 = x

15 = x

Therefore, the answer is 15.

Best of Luck!

88 $cm^{3}$

Step-by-step explanation:

Given 3 measurements 6,11,4

Assuming them to be length, width and height of pyramid

⇒

Length= 6 cm

Width= 11cm

Height= 4 cm

⇒

$\text{Volume of a Pyramid}= \frac{Length \times Width \times Height}{3}$

Therefore Volume of Given Pyramid

= $\frac{6\times 11\times 4}{3} =\frac{264}{3} =88$

⇒Volume of pyramid=88 $cm^{3}$

In a jar of ten beads, seven are red and three are blue. a bead is drawn from the jar five times with replacement. what is the p

MatroZZZ [7]

<span>In a jar of ten beads; since 3 are blue; probability of picking a blue ball, B, = p(b) = 3/10. And P (of not picking a blue ball) ; p(b') = 7/10. Since it occurs with replacement, probabilities doesn't change Probaility of picking k blue balls from on n attempts is given by P_n(k) P_n(k) = (n, k) p^(k) q^(n -k) where p and q are b and b' respectively. P_5(2) = (5 , 2) (0.3)^(2) (0.7)^(5 - 2) P_5(2) = 5C2 (0.3)^(2) (0.7)^(3) = 0.3087</span>
