Answer:
The probability that exactly 2 don't grow is 0.075 or 7.5%
Step-by-step explanation:
Binomial Distribution
Let's consider a random experience with only two possible outcomes. Call p to the probability that the event has a successful outcome and q to the unsuccessful outcome.
It's clear that p+q=1, or q=1-p.
Now repeat the random experience n times. We want to calculate the probability of getting x successful outcomes. This can be done with the following formula:
[tex]\displaystyle P_{x} = {n \choose x} p^{x} q^{n-x}[/tex]
Where
[tex]\displaystyle {n \choose x}[/tex]
Is the number of combinations:
[tex]\displaystyle {n \choose x} =_nC_x=\frac{n !}{x ! (n-x) !}[/tex]
For the problem to solve, each seed has a p=0.95 probability of growing into a healthy plant. The value of q=1-0.95=0.05.
The experience is repeated n=10 times and we want to estimate the probability that 2 of them don't grow. Note this last data is not directly the value of x because it's not related to success but with no success. The value of x is x=10-2=8. That means, 8 out of 10 seeds grow.
Apply the formula:
[tex]\displaystyle P_{8} = {10 \choose 8} \cdot 0.95^{8} \cdot 0.05^{10-8}[/tex]
[tex]\displaystyle P_{8} = 45\cdot 0.95^{8} 0.05^{2}[/tex]
[tex]\displaystyle P_{8} = 0.075[/tex]
The probability that exactly 2 don't grow is 0.075 or 7.5%

Answer:
10²
Step-by-step explanation:
There are 2 "10's" being multiplied.
which fraction is equal to 0.5 7
The value of fraction 0.5 7 is equal to 1/2.
We are given that;
Number = 0.57
Now,
There are different ways to express a fraction as a decimal, but one common method is to divide the numerator by the denominator.
For example, 1/2 as a decimal is 1 ÷ 2 = 0.512.
Another method is to use a fraction to decimal conversion chart or calculator345. According to these sources, 0.5 as a fraction is equal to 5/10 or 1/2.
These fractions are equivalent because they have the same value when simplified or reduced.
To simplify a fraction, we can divide both the numerator and the denominator by their greatest common factor (GCF).
Therefore, by algebra the answer will be 1/2.

Please help me solve this equation and show the work show me how you got the answer
Answer: k=3
Step-by-step explanation:
To solve for k, you want to isolate k.
[tex]\frac{2}{5} (5k+35)-8=12[/tex] [add both sides by 8]
[tex]\frac{2}{5} (5k+35)=20[/tex] [multiply both sides by 5/2]
[tex]5k+35=50[/tex] [subtract both sides by 35]
[tex]5k=15[/tex] [divide both sides by 5]
[tex]k=3[/tex]
Now, we know that k=3.

Answer:
[tex]\boxed{x=10}[/tex]
Step-by-step explanation:
We are given two angles, which together, have a sum of 90°. We call these complementary angles. The angle ∠EAF is the complement of angle ∠FAB and vice versa.
Therefore, because they sum up to be 90°, we can simply add the angles together and solve for x this way.
[tex]4x+5x=90\\\\9x = 90\\\\\frac{9x}{9} = \frac{90}{9}\\\\\boxed{x = 10}[/tex]
The variable x equals 10. We can go even further to check and verify that this is correct by substituting our original value for x into the equation.
[tex]4(10)+5(10)=90\\\\40 + 50 = 90\\\\90 = 90[/tex]
90 does in fact equal 90, so your final answer is x = 10°.
Hope this helps! :)

Car A is traveling east at a steady speed of 60 miles per hour after 2 hours, it is 130 miles east of Johnstown. car B is traveling east on the same road. its distance east of Johnstown is represented by the graph.
Answer:
45 mph = x
Step-by-step explanation:
Engineering manager professional, proficient in all levels of Math
SEE TUTORS LIKE THIS
Distance (D) = Rate (R) * Time (T)
For Car A:
D = 30T {Eqn 1}
For Car B:
The Distance D and the time T is the same as for Car A
But, unlike Car A, Car B travels at two different rates. It travels at 20mph for a time T1. Then it passes Car A and travels at a rate of x for a period of time T2.
D = (20T1) + (x * T2)
Note that T2 must equal the total time T minus T1, so
D = (20T1) + (x * (T - T1)) {Eqn2}
Substitute Eqn 1 into Enq 2 : 30T = 20T1 + xT - xT1
Rewrite as: 30T = 20T1 + x(T-T1) {Eqn 3}
At what point do the two cars pass one another?
Car A travels 30T1 = D1
Car B is traveling in the opposite direction at 20T1 = D2
D2 = D - D1 (where D is the total circular length of the track)
Substituting, 20T1 = D - 30T1. Or 50T1 = D {Eqn 4}
Now we can establish a relationship between T and T1 by substituting Eqn1 into Eqn4
D = 30T = 50T1
30T = 50T1
(30/50)T = T1
T1 = (3/5)T {Eqn 5}
Now substitute Eqn 5 into Eqn 3
30T = 20T1 + x (T-T1)
30T = 20(3/5)T+ x (T - 3/5 T)
30T = 12T + xT(2/5)
18T = (2/5)x
(5/2)18 = x
45 mph = x
Recall that x is the speed that Car B must travel after it passes Car A.

The amount of money earned on a job is directly proportional to the number of hours worked.If $36 is earned for 8 hours of work, how much is earned for 30 hours of work?
Answer:
$135
Step-by-step explanation:
first divide 36 by 8
gives you how much you earn for one hour
36/8=4.5
then multiply
4.5 by amount of hours worked
so 4.5*30=135
The amount of money earned on a job for 30 hours is $135.
The amount of money earned on a job is directly proportional to the number of hours worked.
The amount of money earned for 8 hours of work is $36.
We need to determine the amount earned for 30 hours of work.
Let us determine the amount earned per hour.
Thus,
[tex]\begin{aligned}8\;\rm{Hours \;of\;work}&=\$36\\1\;\rm{Hour \;of\;work}&=\$\dfrac{36}{8}\\&=\$4.5 \end{aligned}[/tex]
Therefore, the amount earned per hour is $4.5.
Now, multiply by 30 to get the amount earned for 30 hours.
Thus, the amount of money earned on a job for 30 hours is $135.

Answer:
B (-5, 3)
Step-by-step explanation:
The line a passes through point ( 2,3 ).
Line b has equation y= -1
Plot the graph for line b, y=-1 , which is a horizontal line as shown in the attached graph
Plot point (2, 3) and draw the graph of line a, y=3 to form a line a parallel to line b
You will notice that point B (-5, 3) is the one the lies on line a.
The answer option A,(2,9) is incorrect because it does not lie on any of the lines
The answer option C (0, 1) is incorrect because it lies along the y-axis
The answer option D (1, 4) is incorrect because it does not lie on any of the lines.

Answer:
μx = 17
σx = 2.2
Step-by-step explanation:
See attachment for full question.
Given:
μ = 17
σ = 22
[tex]n = 100\σ = 22[/tex]
Required
Determine (i) μx and (ii) σx
Solving (i): μx
The mean of a sample means is calculated as thus:
μx = μ
Hence:
μx = 17
Solving (ii): σx
σx = σ/√n
So, we have:
σx = 22/√100
σx = 22/10
σx = 2.2

Men have XYâ (or YX) chromosomes and women have XX chromosomes.â X-linked recessive genetic diseasesâ (such as juvenileâ retinoschisis) occur when there is a defective X chromosome that occurs without a paired X chromosome that is not defective. Represent a defective X chromosome with lowercaseâ x, so a child with the xY or Yx pair of chromosomes will have the disease and a child with XX or XY or YX or xX or Xx will not have the disease. Each parent contributes one of the chromosomes to the child.
Required:
a. If a father has the defective x chromosome and the mother hasgood XX chromosomes, what is the probability that a son willinherit the disease?
b. If a father has the defective x chromosome and the mother asgood XX chromosomes, what is the probability that a daughter willinherit the disease?
c. If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, what is theprobability that a daughter will inherit the disease?
d. If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, what is theprobability that a daughter will inherit the disease?
Answer:
A) 0
B) 0
C) 0
D) 0.5
Step-by-step explanation:
We are told that Men have XY (or YX) chromosomes and women have XX chromosomes
A) If a father has the defective x chromosome and the mother has good XX chromosomes, the four possible outcomes will be;
{xX, YX, YX, xX}
The outcome for the son is;
{YX, YX}
The son will have the disease only if it's xY. Thus, probability of son having the disease is; 0/2 = 0
B) If a father has the defective x chromosome and the mother has good XX chromosomes, the four possible outcomes will be;
{xX, YX, YX, xX}
The outcome for the daughter is;
{xX, xX}
The daughter will have the disease only if it's xx. Thus, probability of daughter having the disease is; 0/2 = 0
C) If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, the possible outcomes are;
{xX, xY, XX, XY}
Outcome for daughter is {xX, XX}
The daughter will have the disease it's xx. Thus, probability of daughter having the disease is; 0/2 = 0
D) If a mother has one defective x chromosome and one good Xchromosome, and the father has good XY chromosomes, the possible outcomes are;
{xX, xY, XX, XY}
The male outcome is;
{XY, xY}
The son will have the disease only if it's xY. Thus, probability of son having the disease is; 1/2 = 0.5
