Answer:

Step-by-step explanation:

The ratio of males to females at a gym is 4:5. There are 20 females at the gym. How many males are in the gym?​

4 : 5 = x : 20

x = 4 * 20 : 5

x = 16

check

4 : 5 = 16 : 20

4 : 5 = 4 : 5

the answer is good

-5 (3 + 5)

-5 (8)

-5 × 8

= -40

Good luck :)

Answer:

-40

Step-by-step explanation:

First you distribute

-5 · 3 = -15

-5 · 5 = -25

Then you add

-15 + (-25) = -40

Answer:

x = 11/7 y = -1/7

Step-by-step explanation:

2x + y = 3

2x + y - 2y = 3 - 2y

y = 3 - 2x

x - 3(3 - 2x) = 2

x - 9 + 6x = 2

x - 9 + 6x + 9 = 2 + 9

x + 6x = 11

7x = 11

7x / 7 = 11/7

x = 11/7

2(11/7) + y = 3

22/7 + y = 3

22/7 + y - 22/7 = 3 - 22/7

y = -1/7

Answer:

(¹¹⁄₇, -⅐)

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}2x+y=3&\\x-3y=2\end{cases}[/tex]

What is the elimination method?

The elimination method is when you rewrite the two equations so that when added together, one of the two variables (x or y) is eliminated.

Step 1: Multiply the first equation by [tex]3[/tex].

[tex]\implies (3)2x+(3)y=(3)3[/tex]

[tex]\implies 6x+3y=9[/tex]

Step 2: Add the above equation to the second equation to eliminate 3y.

[tex]\begin{array}{r l}6x+3y & = 9\\+\ x-3y&=2\\\cline{1-2}7x&=11 \end{array}[/tex]

Step 3: Solve for x (by dividing both sides by 7).

[tex]\implies \dfrac{7x}{7}=\dfrac{11}{7}[/tex]

[tex]\implies \boxed{x=\dfrac{11}{7}}[/tex]

Step 4: Substitute ¹¹⁄₇ as the value of [tex]x[/tex] in any of the given equations and solve for [tex]y[/tex].

[tex]\implies 2\left(\dfrac{11}{7}\right)+y=3[/tex]

[tex]\implies \dfrac{22}{7}+y=3[/tex]

Step 5: Convert [tex]3[/tex] into a fraction and subtract ²²⁄₇ from both sides of the equation.

[tex]\implies \dfrac{22}{7}-\dfrac{22}{7}+y=\dfrac{21}{7}-\dfrac{22}{7}[/tex]

[tex]\implies \boxed{y=-\dfrac{1}{7}}[/tex]

The solution to the given system of equations is (¹¹⁄₇, -⅐).

Answer:

y=1/5x-4

Step-by-step explanation:

Hi there!

We want to write the equation of the line, and we're given that the line has a slope of 1/5, and the y intercept of the line is (0, -4)

There are multiple ways to write the equation of the line, the most popular being slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We are already given the slope (1/5), so we can plug it in as m in the equation.

y=1/5x+b

Now for b, we are also given the y intercept; the value of b is the value of y at the point of the y intercept

In this case, b would equal -4

So substitute -4 as b into the equation:

y=1/5x-4

This is the equation of the line.

Hope this helps!

Using the Poisson distribution, it is found that there is a 0.8647 = 86.47% probability of at least one flaw appearing in 300 square feet.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

The parameters are:

Flaws in a certain type of drapery material appear on the average of one in 150 square feet, hence, considering 300 square feet, the mean is of:

[tex]\mu = \frac{300}{150} \times 1 = 2[/tex]

The probability of at least one flaw appearing in 300 square feet is given by:

[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]

In which:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-2}2^{0}}{(0)!} = 0.1353[/tex]

Then:

[tex]P(X \geq 1) = 1 - 0.1353 = 0.8647[/tex]

0.8647 = 86.47% probability of at least one flaw appearing in 300 square feet.
