Ludmilka [50]3 years ago

5 0

Answer:

m = -5

Step-by-step explanation:

Step 1 :

Pulling out like terms/ factors

Add 5 to both sides of the equation :

-m = 5

Multiply both sides of the equation by (-1) : m = -5

In the Lab, Yolanda has two solutions that contain alcohol and is mixing them with each other. She uses 3 times as much Solution

Mamont248 [21]

Yolanda uses 69 milliliters of solution B to make the mixture.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Let x represent the amount of solution A and y represent the amount of alcohol B, hence:

x + y = 92 (1)

Also:

y = 3x (2)

From both equations:

x = 23, y = 69

Yolanda uses 69 milliliters of solution B to make the mixture.

Suppose that 80 percent of all statisticians are shy, whereas only 15 percent of all economists are shy. Suppose also that 90 pe

Anna71 [15]

Answer:

37.21% probability that the person is a statistician.

Step-by-step explanation:

We have these following probabilities:

An 80% probability that a statistican is shy.

A 15% probability that an economist is shy.

At the gathering, a 90% probability that a person is an economist.

At the gathering, a 10% probability that a person is a statistican.

If you meet a shy person at random at the gathering. What is the probability that the person is a statistician?

This can be formulated as the following question:

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

$P = \frac{P(B).P(A/B)}{P(A)}$

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

What is the probability that the person is a statistican, given that he is shy?

P(B) is the probability of the person being a statistican. So P(B) = 0.1.

P(A/B) is the probability of a statistican being shy, so P(A/B) = 0.8.

P(A) is the probability of a person being a shy. This is 15% of 90%(economists) and 80% of 10%(statisticans). So

$P(A) = 0.15*0.9 + 0.8*0.1 = 0.215$

Finally

$P = \frac{P(B).P(A/B)}{P(A)}$

$P = \frac{0.1*0.8}{0.215} = 0.3721$

37.21% probability that the person is a statistician.

Twice the difference of a number c and forty.

dybincka [34]

Answer:

Equation ----> 2(c - 40)

c = -40

Step-by-step explanation:

2(c - 40)

= (2c) - (80)

= 2c - 80

= $\frac{2c}{2}$ + $(\frac{-80}{2})$

c = -40

abruzzese [7]

Answer:

r=7

Step-by-step explanation:

74000=28000(1+r/12)^12(14)

divide 74000 by 28000, and cancel out 28000.

1.00580=1+r/12

(100) .06962=r

r = 6.96198

the 6 after the 9 rounds 9 to 0, which rounds the 6 to 7
