7. No Broken Hearts [2.5 Points]Robert has a standard deck of 52 playing cards. Robert shuffles the deck, draws a card, andchecks if the card has a suit of hearts. If the card has a suit of hearts he stops. Otherwise,he replaces the card back into the deck and continues to repeat this process until he drawsa card that has a suit of hearts.a) What is the probability that Robert performs exactly 5 draws
Answer:
0.079
Step-by-step explanation:
Number of suit of hearts = 13
Total number of cards in deck = 52
P(drawing a suit of heart) = number of suit of heart / total number of cards in deck
P(drawing a suit of heart) = 13 /52 = 1 /4
Hence, Probability of success, p = 1/4
P(not drawing a suit of heart) = 1 - 1/4 = 3/4
Hence, Probability of performing exactly 5 draws :
To perform exactly 5 draws :
1st draw = not a heart suit
2nd draw = not a heart suit
3rd draw = not a heart suit
4th draw = not a heart suit
5 draw = a heart suit
P(performing exactly 5 draws) =
(3/4 * 3/4 * 3/4 * 3/4 * 1/4)
= 0.0791015625
= 0.079

Answer:
when adding fractions make sure the bottom number is the same
so for number 2 make sure both are 4 on the bottom of the fraction by multiplying by 2 maybe 1/4+2/4 that would equal 3/4 not 1
Answer:
Step-by-step explanation:
1/2+1/4=0.75 less than 1
3/6+2/3=1.17 greater than 1
2/4+1/3=10/12 less than 1

if cot theta = -2, find the value of cot theta + cot (theta -pi) + cot (theta-2pi)
Given:
[tex]\cot \theta = -2[/tex]
To find:
The value of [tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)[/tex].
Solution:
We know that,
[tex]\cot (\theta -n\pi)=\cot \theta[/tex] ...(i)
Where n is an integer.
We have,
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)[/tex]
Using (i), it can be written as
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=\cot \theta +\cot \theta +\cot \theta [/tex]
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3\cot \theta[/tex]
It is given that [tex]\cot \theta = -2[/tex].
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3(-2)[/tex]
[tex]\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=-6[/tex]
Therefore, the value of the given function expression is [tex]-6[/tex].

Answer:
x=4
Step-by-step explanation:
The left and right sides are equal so:
5x-2 + 4x = 7x-4 + x+6
Collect the like terms and calculate the sum :
9x-2 = 8x+2
Move terms and change it's sign:
9x-8x = 2+2
And finally:
x=4
Also if you solve the equations of the other sides you'll find x₁=0.5 and x₂=4
which the intersection with the previous answer will be x=4
a square pyramid has a volume of 30 cubic millimeters and a height of 5 mm what is the area of the base of the pyramid
PLEASE HELP ME AND IF U GIVE ME A LINK OR A FILE I SWEAR.
Answer:
Step-by-step explanation:
V=hb/3, where b=area of base
b=3V/h, since V=30mm^3 and h=5mm then
b=3(30)/5
b=18 mm^2
So the area of the base is 18 square millimeters.

30a + 39b what is the answer
Answer:
[tex]3(10a + 13b)[/tex]
Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
GCF = 3
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
[tex]3( \frac{30a}{3} + \frac{39b}{3} )[/tex]
3) Simplify.
[tex]3(10a + 13b)[/tex]
Therefor, the answer is 3 ( 10a + 13b)

Mr. Wilson is giving his students a vocabulary test tomorrow over all the terms they have learned from this semester. Today, he wants to determine how prepared the students are for the test. So, he writes each term on a note card and puts all the note cards in a paper bag. Then, he asks each student to come to his desk, select five note cards out of the bag, define those five terms, and then put the note cards back in the bag. He records the number of terms each student is correctly able to define.
1. What is the population in this situation? What is the sample? Use complete sentences in your answer.
2. Do you think the data from the sample Mr. Wilson is collecting is representative of the population? Explain your reasoning using complete sentences.

Sarah is redecorating her bedroom and wants to pack away some picture frames. She is using a box that has measurements of 7 1/2 inches long, 3 2/3 inches wide, and 4 1/4 inches tall for storing them.
Part A:
What is the volume of Sarah's box?
Part B:
Each picture frame has a volume of 2 1/2in. Using your findings in Part A, how many picture frames can Sarah fit in her box?
Answer:
A. 71/2 = 35.5 + 32/3= 10.7 + 41/4= 10.3
35.5 + 10.7 + 10.3 = 56.5
B. 21÷2 = 10.5
56.5 ÷ 10.5 = 5.380952381
