Answer:

Hence the length of the base is given by 7 inches.

Step-by-step explanation:

Given:

Volume of a triangular prism=140 ci

Height=4 inches

base height =10 inches.

To Find:

Length of base

Solution:

We know that ,

Volume of triangular prism is given by

V=1/2(base *height* length)=1/2*b*h*l

Here V=140 ci

b=10 inches ,h=4 inches.

140=1/2*(10*4*l)

280=40l

l=280/40

l=7 inches

Answer:

The length of the base is 7 inches.

Step-by-step explanation:

A triangular prism with base height h, length l, and base length b has volume V given by

V=\frac{1}{2}lbh

We are told that the volume of the prism is 140 cubic inches, and h=10, l=4; therefore we have:

140=\frac{1}{2}(4)(10)b

b=\frac{140*2}{4*10} =7\:inches

\boxed{b=7\:inches}

The length of the base is 7 inches.

Answer:

There is a 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.

Step-by-step explanation:

For each question, there are only two possible outcomes. Either it is correct, or it is not. This means that we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which  is the number of different combinatios of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.

In this problem we have that:

There are four questions, so n = 4.

Each question has 5 options, one of which is correct. So  

What is the probability that he answers exactly 1 question correctly in the last 4 questions?

This is  

There is a 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.

an art dealer makes a 17.5% commission on every painting sold. If a painting sold for $1500, what was the commission
Aleksandr [31]
A percentage is a number out of 100.  So, 17.5% is really 17.5/100, or 0.175.

To find 17.5% of 1500, you multiply 1500 by 0.175

1500 x 0.175 = 262.5.

The commission is $262.50.
