Answer:
1. D) 75 inches
2. A) 27 square feet
Step-by-step explanation:
1. You need to convert 6 feet to inches. In one foot, there are 12 inches. Multiply 6 by 12 to find the number of inches in 6 feet. Add 3 inches to the product to find the total number of inches.
6 × 12 = 72
72 + 3 = 75
You will have 75 inches in total.
2. Use the formula to solve. You are given the base and the height already. Simply plug in and solve.
A = 1/2BH
A = 1/2(6)(9)
A = 3(9)
A = 27 ft²
The area is 27 ft².

What would I get by solving by polynomials?
Answer:
x=0 or x=3 or x= -3⅘
Step-by-step explanation:
Please see attached picture for full solution.
Another way to solve it is to factorise x out from the equation from the beginning. This would leave you with
x(5x² +4x -57x)=0
Then you can factorise the quadratic equation.
x(x -3)(5x +19)= 0
And solve it just like we did above.
x=0 or x-3=0 or 5x+19=0
x=3 or 5x= -19
x= -3⅘

24 2 47 34
14 21 11
15 12
Shall we reject or not reject the claim that there is no difference in the population mean three-circle red-on-white sherd counts for the four sites? Use a 5% level of significance.
Answer:
Step-by-step explanation:
Hello!
The objective is to test if the population mean of three-circle red-on-white sheds is equal to the four excavation sites.
To compare the population means you have to apply an ANOVA. For this test the variable of interest is
X: number of three-circle red-on-white sheds.
There is only one factor: "Site" with four treatments "I, II, III; IV"
H₀: μ₁= μ₂= μ₃= μ₄
H₁: At least one population mean is different.
α: 0.05
[tex]F= \frac{MS_{Treatment}}{MS_{Error}} ~~F_{K-1;N-K}[/tex]
Df treatments: k-1= 4-1= 3 (k= nº of treatments)
Df errors: N-K= 21-4= 17 (N= total observations for all treatments)
[tex]F_{H_0}= \frac{102.72}{117.08}= 0.88[/tex]
p-value: 0.4723
Using the p-value approach the decision rule is:
p-value ≤ α, reject the null hypothesis.
p-value > α, do not reject the null hypothesis.
The p-value is greater than the level of significance, the decision is to reject the null hypothesis.
Using a 5% significance level, there is not significant evidence to reject the null hypothesis. Then you can conclude that the population mean three-circle red-on-white sherd count is equal to all the excavation sites.
I hope this helps!

If 24 tomatoes cost $3.55 how much does 6 tomatoes cost?
Will mark brainlest for correct answer!
Answer:
0.89
Step-by-step explanation:
First, let’s find out what one tomato costs. To do this, we need to find the unit rate.
To find the unit rate, divide the cost by the number of tomatoes.
cost/number of tomatoes
It costs $3.55 for 24 tomatoes.
cost=3.55
number of tomatoes=24
Substitute these values in.
3.55/24
0.147916666666667
Each tomato costs $0.147916666666667
Now, we have to find out what 6 tomatoes cost.
Multiply the number of tomatoes by the cost of one tomato
number of tomatoes * cost of one
number of tomatoes=6
cost of one= 0.147916666666667
Substitute these values in.
6* 0.147916666666667
0.8875
Round to the nearest cent or hundredth.
The 7 in the thousandth place tells us to round the 8 in the hundredth place up to a 9.
0.89
6 tomatoes will cost about 0.89.

Calculate each probability
given that P(A) = 0.2, P(B)
= 0.8, and A & B are
independent.
Complete question:
Calculate each probability given that P(A) = 0.2, P(B) = 0.8, and A & B are independent.
a) compute P(A and B)
b) If P(A|B) = 0.7, compute P(A and B).
Answer:
(a) P(A and B) = 0.16
(b) P(A and B) = 0.56
Step-by-step explanation:
Two events are independent if occurrence of one event does not affect possibility of occurrence of another.
(a) if A and B are independent, then P(A and B) = P(A) x P(B)
= 0.2 x 0.8
= 0.16
(b) If P(A|B) = 0.7, compute P(A and B)
Considering the notations of independent events,
[tex]P(A/B) = P(A)\\\\\frac{P(A \ and \ B)}{P(B)} = P(A)\\\\Thus, P(A/B) = \frac{P(A \ and \ B)}{P(B)}\\\\P(A \ and \ B) = P(A/B) *P(B)[/tex]
= 0.7 x 0.8
= 0.56
A rectangular board is 1.5 meters long and 1.2 meters wide. What is the area of the board in square millimeters?

Buying a house is most likely a long-term goal for a person of which of these
ages?
A. 19 years old
B. 79 years old
C. 69 years old
O
D. 59 years old
Answer:
A. 19 years old
Step-by-step explanation:
A person at the age of 19 is probably still in college . He/She is probably investing more time and finance in his/her education. A person at age 19 is still building his or her career . He/she is likely to have limited working experience. He/she has more years ahead of him to invest his little income(that is if he has any) for a longer term plan like owning a house and building a business.
In fact at age 19 a person is more concern in his/her career development and studies. Buying a house is most likely a long time goal for a person of 19 years old because he has so many year ahead of him to gather or create wealth for himself.
The other ages 59, 79 and 69 years are individuals who have probably amassed wealth . They probably have over 3 decades of working experience and this working years will reflect in their savings. people at this age have shorter time to work or are probably even retired.
Answer:
A. 19 years old
Step-by-step explanation:
19 years old because usually by the time someone between the ages of 59 and 79 should already own or be renting a house if they have set their financial goals correctly.

A certain federal agency employs three consulting firms (A, B and C) with probabilities 0.40, 0.45 and 0.15. From past experiences, it is known that the probability of cost overruns for the firms are 0.01, 0.14, and 0.17, respectively. Suppose that a cost overrun is experienced by the agency. What is the probability that the firm involved is firm B
Answer:
68.11% probability that the firm involved is firm B
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)}[/tex]
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Cost overrun
Event B: Agency B used.
A certain federal agency employs three consulting firms (A, B and C) with probabilities 0.40, 0.45 and 0.15.
This means that [tex]P(B) = 0.45[/tex]
From past experiences, it is known that the probability of cost overruns for the firms are 0.01, 0.14, and 0.17, respectively.
This means that [tex]P(A|B) = 0.14[/tex]
Probability of cost overrun.
Firm A is used 40% of the time, with 1% of these having cost overrun. B is used 45%, with 14% of these having cost overruns. C is used 15% of the time, with 17% of these having cost overruns.
So
[tex]P(A) = 0.4*0.01 + 0.45*0.14 + 0.15*0.17 = 0.0925[/tex]
What is the probability that the firm involved is firm B
[tex]P(B|A) = \frac{0.45*0.14}{0.0925} = 0.6811[/tex]
68.11% probability that the firm involved is firm B

Answer:
The mass of wood is 4309.65 kg.
Step-by-step explanation:
Volume of a cylinder is:
[tex]V = \pi r^{2} h[/tex]
Where [tex]r[/tex] is the radius of base of cylinder
and [tex]h[/tex] is the height of the cylinder
[tex]r=\dfrac{d}{2}[/tex]
[tex]d[/tex] is the diameter of base of cylinder.
A tree's trunk is in the shape of cylinder only. And we are given the following details:
[tex]d = 0.5m\\\Rightarrow r = \dfrac{0.5}{2} m[/tex]
[tex]h =36 m[/tex]
[tex]V = \pi (\dfrac{0.5}{2})^2 \times 36\\\Rightarrow V = 7.065\ m^3[/tex]
Density of wood of tree = 610 kg per cubic meter
Mass of trunk = Volume [tex]\times[/tex] density

The growth in the mouse population at a certain county dump can be modeled by the exponential function A(t)= 906e0.012t, where t is the number of months since the population was first recorded. Estimate the population after 36 months.
Answer:
[tex] A(t) = 906 e^{0.012t}[/tex]
Where t is the number of months since the population was first recorded. And we want to find the population after 36 months so we need to replace t=36 months into the function and we got:
[tex] A(36) = 906 e^{0.012*36}= 1395.54[/tex]
So then we can conclude that after 36 months the population of mouse is between 1385 and 1396.
Step-by-step explanation:
We know that the population can be represented with this formula:
[tex] A(t) = 906 e^{0.012t}[/tex]
Where t is the number of months since the population was first recorded. And we want to find the population after 36 months so we need to replace t=36 monthsinto the function and we got:
[tex] A(36) = 906 e^{0.012*36}= 1395.54[/tex]
