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
Answers
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

Answers
Answer:
x = 3.5
Step-by-step explanation:
diagonals bisect each other so AW = OW
since AO = 22 then AW = 11
11 = 4x - 3
14 = 4x
x = 7/2 or 3 1/2
What is the Genotypic and Phenotypic ratio?
Answers
Answer:
The phenotypic ratios are the ratios of visible characteristics. The genotypic ratios are the ratios of gene combinations in the offspring, and these are not always distinguishable in the phenotypes.
Genotype is the genetic make-up of an organism that describes the nature of each trait. (the letters we often write for a certain trait)
What is the Genotypic and Phenotypic ratio?Genotype is the genetic make-up of an organism that describes the nature of each trait. (the letters we often write for a certain trait)
Phenotype is the morphology of a living organism .(the trait you usually observe while looking/tracking the organism)
For an Example:
In the flower of a pea plant there are a pink color(RR) or (Rr) and a white color(rr).
When crossing two hybrid ( with two different letters) pink colors,
P : Rr × Rr
G : R r R r
F1 : RR Rr Rr rr
The phenotype ratio will be (3 pink : 1 white)
The genotype ratio will be [1 (RR) : 2 (Rr) : 1 (rr)]..
Hence Genotype is the genetic make-up of an organism that describes the nature of each trait. (the letters we often write for a certain trait)

Select the correct answer.
A researcher for a travel company is looking into the prices people are willing to pay for airplane tickets. The company has communicated that the overall population mean is $265 with a standard deviation of $40.93. The researcher has a sample of 130 ticket purchases from one location.
By the central limit theorem, which interval can the researcher be 95% certain that the sample mean will fall within?
Answers
From the central limit theorem, the interval can the researcher be 95% certain that the sample mean will fall within A. $257.82 and $272.18.
How to use the Central limit theorem?
We are given;
Population Mean; μ = $265
Population standard deviation; σ = $40.93
Sample size; n = 130
The central limit theorem (CLT) postulates that the distribution of sample mean approximates a normal distribution with larger sample sizes, disregarding the population's distribution.
This implies that sample sizes equal to or greater than 30 are often considered sufficient for the Central limit theorem to hold.
Thus, by the central limit theorem, the interval can the researcher be 95% certain that the sample mean will fall within A. $257.82 and $272.18.

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

Which number is prime 9,10,11,12
Answers
Answer:
11
Step-by-step explanation:
A prime number is a number that cannot be factored other than 1 and that number is self thus, 11 will be the prime number.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
A prime number is a number that cannot be factored other than 1 and that number is self.
For example, 9 can be written as 3 x 3 thus it will not prime number and 11 cannot be written as two products other than 1 x 11 thus it will be a prime number.
Hence "A prime number is a number that cannot be factored other than 1 and that number is self thus, 11 will be the prime number".
