Answer:

99.6 ft²

Step-by-step explanation:

Three faces are equal triangles with:

base = 8 units, height = 6 ft

The base is a triangle with:

base = 8 ft, height = 6.9 ft

Surface area is sum of areas of 4 faces:

S = 3*(1/2*8*6) + 1/2*8*6.9 = 99.6 ft²

A person aiming at a target receives 10 points if their shot is within 1 inch of the target, 5 points if it is between 1 and 3 i

Gelneren [198K]

Answer:

standard deviation is 2.886 [expected points]

Step-by-step explanation:

Let x is number of points scored so that given target uniformly dstributed between 0 and 10

clearly X uniform(0,10)

mean is defined as $E(x) = \frac{a+b}{2}$

$\frac{0+10}{2} = 5$

we know that variance is given as $\frac{(b-a)^2}{12}$

$V(x) = \frac{(b-a)^2}{12}$

$\frac{(10-0)^2}{12}$

= 8.333

therefore standard deviation is $\sqrt{V(x)} = \sqrt{8.333}$

standard deviation is 2.886 [expected points]

you help a teacher move books. the math books weigh 3 pounds each. the science books weigh 4 pounds each. you can carry 24 pound

Radda [10]

Answer:

see the attachment for a graph
yes, you can carry 5 math books in one load (along with 0–2 science books)

Step-by-step explanation:

If x and y represent the number of math and science books you're carrying, respectively, then 3x and 4y represent their weights in pounds.

The total weight of the carry will be 3x+4y, and you want that to be at most 24 pounds. The expression modeling this is ...

... 3x +4y ≤ 24

A graph of this inequality is shown in the attachment. (We have added the constraints that the number of books not be negative.)

___

5 math books will weigh 5·3 = 15 pounds, so will be within the limit you can carry.
