Answer:

When y = 5; x = 2

Step-by-step explanation:

What we have to do here is to first go to the point y = 5 on the y-axis

Now, the next thing is to trace this to the plot

The tracing will meet the plot at a point

At this point, we can now drop a line to the x-axis

By this, we can get that at y = 5; then x = 2

Now, we want to check the validity from the linear equation given

That would be;

y = -x + 7

y = -2 + 7

y = 5

This holds according to the linear equation given

A campus has 55% male students. Suppose 30% of the male students pick basketball as their favorite sports compared to 20% for fe

krok68 [10]

This is question of probability finding using bayes theorem
It is used to calculate probability of two competing statements
now p(m) = .55
p(~m)= .45
now for basketball for male
p(b|m)=.30
and for female
p(b|~m)=.20
so by bayes theorem
p(m|b)=p(b|m)*p(m)/(p(b|m)*p(m)+p(b|~m)*p(~m))
so answer is E
(.55)(.30) / (.55)(.30) + (.45)(.20)

Francis is at the state fair. A fair concession stand is selling funnel cakes for $3.50 and deep-fried Oreos for $2.00. Write an

VladimirAG [237]

The equation that models the number of funnel cakes and Oreos he can buy is 3.50x + 2.0y = 42

Data given;

Cost of cakes = $3.50

Cost of Oreos = $2.00
The total amount spent = $42.00

<h3>What is the Equation</h3>

To solve this problem, we just need to write out an equation to show how he can spend $42.00 in the fair on Oreos and Cakes.

Let x represent the cakes

Let y represent the Oreos

The equation is thus;

$3.50x + 2.0y = 42.00$

The equation that shows the number of Cakes and Oreos can by is

3.50x + 2.0y = 42

7nadin3 [17]

Answer:

a) -27 a³ b⁶

Step-by-step explanation:

Explanation:-

Given ( -3 ab² )³

By using (ab )ⁿ = aⁿ bⁿ

( -3 ab² )³ = (-3)³ a³ (b²)³

Again , using formula $(a^{m} )^{n} = a^{mn}$

= -27 a³ b⁶
