Answer:

-3/4

Step-by-step explanation:

You can use the rise over run method to calculate between the 2 points or y2-y1 over x2-x1. Both methods will work.

If you liked my answer please mark it as the brainliest that would be much appreciated. Thanks! :D

Answer:

$12-c$ Cookies

A toddler is allowed to dress himself on Mondays, Wednesdays, and Fridays. For each of his shirt, pants, and shoes, he is equall

avanturin [10]

Answer:

0.0286 = 2.86% probability that today is Monday.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Dressed correctly

Event B: Monday

Probability of being dressed correctly:

100% = 1 out of 4/7(mom dresses).

(0.5)^3 = 0.125 out of 3/7(toddler dresses himself). So

$P(A) = 0.125\frac{3}{7} + \frac{4}{7} = \frac{0.125*3 + 4}{7} = \frac{4.375}{7} = 0.625$

Probability of being dressed correctly and being Monday:

The toddler dresses himself on Monday, so (0.5)^3 = 0.125 probability of him being dressed correctly, 1/7 probability of being Monday, so:

$P(A \cap B) = 0.125\frac{1}{7} = 0.0179$

What is the probability that today is Monday?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0179}{0.625} = 0.0286$

0.0286 = 2.86% probability that today is Monday.

PLEASE HELP PLEASE PLEASE PLEASE PLEASE

Delvig [45]

Answer:

1: 98

2: 82

3: 98

4: 82

Step-by-step explanation:

So 2 is 82deg then the opposite is also 82 so 4 is 82deg

Then 82+82 = 164deg, and we remain with 360deg-164deg which is = 196.

Since the other two angles will be equal (they are opposite each other) we can decide 196/2 = 98

So 3 and 1 are 98deg

Joshua sells 13 toys per hour. Sarah sells 16 toys per hour. This week Sarah sold an additional 20 toys. Write an expression tha

snow_tiger [21]

Assuming that they each work 24hrs a day 7 days a week (I haven't got anything else to go on...sorry) to find the total for Joshua you must first multiply 13x24 = 312, for the toys sold per day, and then 312x7 = 2184, for the number of days per week. so j = 2184
then for Sarah's total we must first multiply 16x24 = 384 for the toys sold per day and then 384x7 = 2688 for the toys sold per week. and 2688+20 = 2708 for the extra 20 she sold. so s = 2708

REMEMBER, THIS IS ASSUMING THEY WORK 24/7 MEANING THEY WORK 168 HOURS PER WEEK.

IF YOU NEED A DIFFERENT ANSWER LET ME KNOW AND I'LL TRY TO FIX IT. IF YOU LET ME KNOW THE HOURS THEY WORKED I CAN DO TAT FOR YOU AS WELL.
