Marina86 [1]

Answer:

36 fries

Step-by-step explanation:

Michael has a probability of 0.3.

Lidia has a probability of 0.1.

Alexandra has the probability of 0.32.

Catherine has the probability of 0.1.

Let the probability of Ronald be x

Sum of all the probabilities must be 1

So, $0.3+0.1+0.32+0.1+x=1$

$0.82+x=1$

$x=0.18$

So, probability of Ronald is 0.18

We are given that here are 200 fries in the basket.

So, the number of fries that Ronald will eat = $0.18 \times 200 =36$

Hence Ronald will eat 36 fries.

Answer:

The height of the given rectangular prism is 5cm.

Step-by-step explanation:

Given that the volume of the rectangular prism is $5cm^3$

And length is $\frac{3}{4}$ and width is $1\frac{1}{3}$

That is V=5cm^3[/tex] , $l=\frac{3}{4}cm$ and $w=1\frac{1}{3}cm$

We have the volume of the rectangular prism V=lwh cubic centimeter

$V=lwhcm^3$

Substituting the values in above formula

$5=\frac{3}{4}\times 1\frac{1}{3}\times h$

$5=\frac{3}{4}\times \frac{4}{3}\times h$

$5=1\times h$

$5=h$

Rewritting as below

$h=5cm$

Therefore the height is 5cm

The value 5pi/24 is a solution for the equation 4 cos^2 (4x)-3=0. True or false

Margaret [11]

Let's check.

x = 5π/24

4x = 5π/6

cos 4x = cos(5π/6) = cos 150° = -√3/2

cos² 4x = (-√3/2)^2 = 3/4

4 cos² 4x -3 = 4 (3/4) - 3 = 0

Answer: TRUE
