Answer:

268.

Step-by-step explanation:

So we have 51*23+49+49*11*-11+51*-23

2(51+23+49+11) ( the 2 negatives cancel out)

So, 51+23+49+11 is 134.

2(134)

or 268.

Hope this answers your question!!!

A circle with a radius of 10,20 or 4 inches has a central angle of 0.25 radians that intercepts an arc of 25,5 or 16 inches

WARRIOR [948]

The radius would be 10 and the arc would be 5.

The diameters of Douglas firs grown at a Christmas Tree Farm are normally distributed with a mean of 4 inches and a standard dev

leva [86]

Answer:

The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.

Step-by-step explanation:

In this problem we have a normal ditribution with mean of 4.0 in and standard deviation of 1.5 in.

The proportion of the trees that are expected to have diameters greater than 5 inches is equal to the probability of having a tree greater than 5 inches.

We can calculate the z value for x=5 in and then look up in a standard normal distribution table the probability of z.

$z=\frac{x-\mu}{\sigma}=\frac{5-4}{1.5}=0.67$

$P(x>5)=P(z>0.67)=0.25$

The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.

The length of a rectangular prism is 4√3 units. The height is 3√6 units. If the volume is irrational, which could be the measure

Jet001 [13]

Volume = length * height * width
= 4 qrt3 + 3 sqrt6 * w
= 12 sqrt18 w

let w = 2 sqrt50 then volume = 2*12 * sqrt 18*50 = 24*30 so this is rational

let w = 4 sqt 12 the v = 48 sqrt12 * sqrt 18 = 48 sqrt30 which is irrational

C and D are rational
answer is B
