Alla [95]

The probability that a student is a female or major in civil engineering is 62%

<h3>How to determine the probability?</h3>

Let A represent Female and B represents civil engineering.

So, we have:

P(A) = 49%

P(B) = 21%

P(A and B) = 8%

The required probability is calculated as:

P(A or B) = P(A) + P(B) - P(A and B)

This gives

P(A or B) = 49% + 21% - 8%

Evaluate

P(A or B) = 62%

Hence, the probability that a student is a female or major in civil engineering is 62%

<h3>Complete question</h3>

At a certain college, 49% of the students are female, and 21% of the students major in civil engineering. Furthermore, 8% of the students both are female and major in civil engineering. What is the probability that a randomly selected female student majors in civil engineering?

The area of a triangular flag is 56 square centimeters. It’s altitude is 2 centimeters longer than twice it’s bases find the len
MrMuchimi

Answer:

The length of the altitude is 16 centimeters and the base is 7 centimeters

Step-by-step explanation:

we know that

The area of triangle is equal to

A=\frac{1}{2}bh ----> equation A

where

b is the base and h is the height

h=2b+2 ----> equation B

substitute equation B in equation a

A=\frac{1}{2}b(2b+2)

we have that

A=56\ cm^2

so

56=\frac{1}{2}b(2b+2)

112=2b^2+2b

2b^2+2b-112=0

solve the quadratic equation by graphing

the solution is b=7 cm

see the attached figure

Find the value of h

h=2(7)+2=16\ cm

therefore

The length of the altitude is 16 centimeters and the base is 7 centimeters

On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, negative 3) and point B is at (negative 4, 9).
zimovet [89]

Answer: (0,1)

Step-by-step explanation:

If (x_1, y_1) and  (x_2, y_2) are two point son a coordinate plane and (x,y) dividing it in a ratio of m: n.

Then , the coordinates of (x,y) is given by :-

x=\dfrac{nx_1+mx_2}{m+n}

y=\dfrac{ny_1+my_2}{m+n}

Given : On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, - 3) and point B is at (- 4, 9).

Then , the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 :

x=\dfrac{2(2)+1(-4)}{1+2}=0

y=\dfrac{2(-3)+1(9)}{1+2=1}

Hence, the x- and y- coordinates of point E = (0,1)
