MATH!!! find the volume of the pyramid. pleaseee answer correctly and tell me how you got your answer.
bagirrra123 [75]

The area of polygons formulas to V=2.56m^2

We have to determine,

The volume of the pyramid.

<h3>What is the volume of the pyramid?</h3>

The volume of a pyramid is found using the formula,

V = (1/3) Bh

where 'B' is the base area and 'h' is the height of the pyramid.

hight =2.4m

base=1.4+1.8

base=3.2m

V = (1/3) (3.2)(2.4)

V=2.56m^2

As we know the base of a pyramid is any polygon,

we can apply the area of polygons formulas to find 'B.

V=2.56m^2.

A plane rises from take off and flies at an angle 11° with the horizontal runway. When it has gained 750 feet find the distance
kogti [31]

Answer:

D=3930.632298 \approx 3930.6miles

Step-by-step explanation:

From the question we are told that

Angle  \theta=11\textdegree

Height of plane h  =750feet

Generally the equation for the total distance flown is mathematically given by

D=\frac{h}{sin\theta}

D=\frac{750}{sin11}

Therefore total distance flown is

D=3930.632298 \approx 3930.6miles

Set of data has a normal distribution with a mean of 56 and a standard deviation of 7. Find the percent of data within the follo
makvit [3.9K]

Answer:

.99815

which is about

99.815%

Step-by-step explanation:

we are looking for 35<x<77

We need to find (what I think is called) the z score which is acheieved through what I'm pretty sure is called standardizing

What we do is subtract the mean and then divide by the standard deviation

so for 35 we have

(35-56)/7= -3.29

due to the fact that the normal distribution is symmetric this is equal to 1-p(3.29)

to find p(3.29) grab a ztable and get p(3.29)= .9995

1-.9995= .0005

For 77 we have

(77-56)/7=3

grab a ztable and find the 3= .99865

Finally subtract these two to get the final answer

.99865-.0005= .99815
