Answer:
i. Predicted chi-square value(x^2)?______ 22.35
ii. df_______ 6-1= 5
iii. Using the critical values table, determine the predicted P value
The P-Value is .050985 for 5 df and 0.05 significance level. The result is not significant at p < .01.
The P-Value is .010362 for 5 df and 0.01 significance level. The result is not significant at p < .01.
Step-by-step explanation:
Phenotype Predicted ( o) Expected (e) (o-e) (o-e)²/e
(observed)
A- normal 19 3/4 * (1/4)= 3/16 25.5 -6.5 1.66
O normal 5 1/4 * (1/4)= 1/16 8.5 -3.5 1.44
A trait 70 3/4 * (1/2)= 3/8 51 19 7.07
O trait 25 1/4 * (1/2)= 1/8 17 8 3.67
A Disease 13 3/4 * (1/4)= 3/16 25.5 -12.5 6.13
O Disease 4 1/4 * (1/4)= 1/16 8.5 -4.5 2.38
136 136 22.35
i. What is your predicted chi-square value(x^2)?______ 22.35
ii. Calculate df_______ 6-1= 5
iii. Using the critical values table, determine the predicted P value
The critical region for alpha =0.05 is χ² ≥ χ² (0.05,5) = 11.02
The P-Value is .050985. The result is not significant at p < .01.
The critical region for alpha =0.01 is χ² ≥ χ² (0.01,5) = 15.00
The P-Value is .010362. The result is not significant at p < .01.
The calculated value of chi square is 22.35 which is greater than 15.00 and 11.02 , the critical regions at alpha 0.05 and 0.01
Therefore it falls in the critical region and the result is insignificant.
hich expression is equivalent to -4(7 - 2m) + 11m?
Answer:
[tex] - 4(7 - 2m) + 11m \\ = - 28 + 8m + 11m \\ = \boxed{19m - 28}[/tex]
Expression (19m-28) is equivalent to -4(7 - 2m) + 11m.
a sequence of payment made at equal time period is a/an'????
Answer:
Annuity.
Step-by-step explanation:
A sequence of payment made at equal time period is called an annuity.
Basically, annuity can be calculated using the compound interest formula. It is given by the mathematical expression;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Additionally, the time period between each payment is called payment period.
The term of an annuity refers to the time from the beginning of the first payment made by an individual to the end of the last payment period.

Tickets for an upcoming concert are sold out but a local charity is having a raffle and the prize is a pair of tickets to the concert. One hundred people enter the raffle, so each individual who entered has 1/100 probability of winning the pair of tickets. You and a friend both entered. What is the probability that one or the other of you wins the tickets
Answer:
[tex]P(A\ or\ B) = \frac{1}{50}[/tex]
Step-by-step explanation:
Represent the event that you win with A and the even that your friend win with B.
So, we have:
[tex]P(A) = \frac{1}{100}[/tex]
[tex]P(B) = \frac{1}{100}[/tex]
Required
Calculate P(A or B)
Both events are mutually exclusive.
So:
[tex]P(A\ or\ B) = P(A) + P(B)[/tex]
Substitute values for P(A) and P(B)
[tex]P(A\ or\ B) = \frac{1}{100} + \frac{1}{100}[/tex]
Take LCM
[tex]P(A\ or\ B) = \frac{1+1}{100}[/tex]
[tex]P(A\ or\ B) = \frac{2}{100}[/tex]
Simplify:
[tex]P(A\ or\ B) = \frac{1}{50}[/tex]
Luisa deposits $44.60 to her bank account on Tuesday morning. on Wednesday, she withdraws $66.30 on Thursday, she wildew $30 Which answer choke represents the balance in her account on Thursday?
A $51.70
B $140.90. C $ -22.00. D $-51.70
Answer:
The answer is D- $- 51.70
The answer choke represents the balance in her account on Thursday is D $-51.70
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Given that Luisa deposits $44.60 to her bank account on Tuesday morning. on Wednesday, she withdraws $66.30 on Thursday, she wildew $30
Using the data from the question, we can create the following equation to solve.
44.60 - (66.30 + 30 ) = x
44.60 - (96.30 ) = x
-51.70 = x
As we can see Luisa withdrew more money than what she actually deposited which means that her account balance on Tuesday Night is less than what it was on Monday night before the initial deposit.

Answer:
The answer is b=128
Step-by-step explanation:
25+27=52
180-52=128
Answer:
∠A + ∠B + ∠C = 180°
⇒ 25° + 27° + ∠B= 180°
⇒ 52° + ∠B= 180°
Subtract both sides by 172°
⇒ 52° – 52° + ∠B = 180° – 52°
Therefore, ∠B = 128°
the jet stream is a wind current that flows across the US from west to east. Flying with the jet stream, an airplane flew 2700 miles in 4.5 hours. Against the same wind, the return trip took 6 hours. Find the speed of the plane in stil air and the speed of the jet stream.
Answer:
The speed of the plane in still air and the speed of the jet stream are 525 miles per hour and 75 miles per hour.
Step-by-step explanation:
From Mechanical Physics, we know that absolute velocity of the airplane ([tex]v_{A}[/tex]) is equal to sum of the absolute velocity of the jet steam [tex](v_{J})[/tex] and the relative velocity of the airplane with respect to jet stream (velocity of the airplane in still air) ([tex]v_{A/J}[/tex]). Al velocities are measured in miles per hour. Let suppose that both jet stream and airplanes travels at constant velocity. Now, we construct the following system of linear equations:
Flight with the jet stream
[tex]v_{J}+v_{A/J} = \frac{2700\,mi}{4.5\,h}[/tex]
[tex]v_{J}+v_{A/J} = 600\,\frac{mi}{h}[/tex] (1)
Flight against the jet stream
[tex]v_{J} -v_{A/J} = -\frac{2700\,mi}{6\,h}[/tex]
[tex]v_{J}-v_{A/J} = -450\,\frac{mi}{h}[/tex] (2)
The solution of this system of linear equations is:
[tex]v_{J} = 75\,\frac{mi}{h}[/tex], [tex]v_{A/J} = 525\,\frac{mi}{h}[/tex]
The speed of the plane in still air and the speed of the jet stream are 525 miles per hour and 75 miles per hour.

Jasper is eating tacos at a constant rate. The amount of tacos depends on time.
y= 2.5x
y is the number of tacos eaten
x is the time in minutes
what is the rate of change of jaspers taco eating capabilities?
how many tacos will jasper consume in 9mins
Answer:
The rate of change, I believe, based on what you have given us in terms of information, would be 2.5. Because Jasper would eat 2.5 tacos per minute; thus, the rate would increase by 2.5 each time.
And for the second part, you would simply multiply 2.5 by 9 to get 22.5. Jasper would eat 22.5 tacos in 9 minutes.

Bea is buying pens and pencils. Pens cost $2 and pencils cost $1. She plans on spending no more than $10 and wants to buy at least 10 items. Which two inequalities model this situation?
Well each pen costs $2 and each pencil costs $1.
One of the equations would be
2p + 1c ≤ 10
She doesn’t want to spend more than 10 dollars but wants to get 10 items. So she’ll be spending $10. For the pencils.
1c ≤ 10 c = 10
1(10) ≤ 10
10 ≤ 10
Now for the pens
2p ≤ 10
2. 2
P = 5
5 ≤ 10
Anymore will go over her budget. She wants to buy at least 10 items not 10 exactly so she can buy 5 pens or 10 pencils.
