Answer:

YES

Step-by-step explanation:

If you look at them, they are proportional.

$\frac{56}{72} = \frac{7}{9}\\$

56 / 7 is 8
72/9 is 8

If you multiply both the numerator and denominator of the 7/9 by 8 you will get 56/72.

Hope it helps :>

Yes because 56/8 = 7
And 72/8 = 9.
Together they make 7/9.

Karla makes paper airplanes. Today, it takes her 32 min to make 16 paper airplanes.

Pavel [41]

Answer:

48/b

Step-by-step explanation:

32÷16=2 so it takes two minutes per airplane. if she makes airplanes for 96 minutes at the same pace (2 min per airplane) then you need to divide 96 by 2 which gives you 48!

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following p

igor_vitrenko [27]

The required probability of success is given by 0.98906500

Assume the random variable X has a binomial distribution with the given probability of obtaining a success.
P(X<5), n=6, p=0.3

<h3>What is binomial distribution?</h3>

In binomial distribution for number trials we are investigating the probability of getting a success remain the same.

n = number of trails,
p = probability of success
x = the number of success

p(x<5) = P(x=0)+ p(x=1) + p(x=2)+p(x=3)+p(x=4)

= $\binom{6}{0}(0.3)^0(1-0.3)^6+\binom{6}{1}(0.3)^1(1-0.3)^5+\binom{6}{2}(0.3)^2(1-0.3)^4+\binom{6}{3}(0.3)^3(1-0.3)^3+\binom{6}{4}(0.3)^4(1-0.3)^2$

p(x<5) = 0.98906500

Thus the required probability of success is given by 0.98906500

The above figure is a special trapezoid. Explain the relationship between the mB and mC

artcher [175]

Answer:

They are supplementary

Step-by-step explanation:

Since AB and DC are parallel, then the alternate interior angles are congruent because there is transversal cutting the parallel lines (BC). So m<B is supplementary to m<C

What is the equation of a line parallel to 3 x plus 4 equal y and passing through open parentheses 4 comma space minus 2 close p

nekit [7.7K]

Step-by-step explanation:

since the two lines are parallel, slope of the line is Sam so it's 3.

let eqn of the line be y = 3x + b.

sub (4, -2):

4 = 3(-2) + b

b = 10

therefore, equation of the line is y = 3x + 10
