Tom hypothesizes that there is a relationship between air pressure and rainfall. He records air pressure and rain amounts for three months. Each month, he seems to get different results. What is the most likely explanation for this?

Answers

Answer 1

Answer:

Missing data points

Step-by-step explanation:

Given that there are 12 calendar months in a year, and there are clearly defined raining season in some areas which may last for months, following periods of low rainfall or zero precipitation, the sample should include all the months of the year so as to ensure, that the effect that causes rainy season such as the landward direction of moist air from the sea or the seaward of air during periods of dry season.

Other possible causes includes;

Heteroscedasicity

This occurs when the variability of the dependent variable is not constant with regards to the independent variable

Multiple linear regression

The relationship between rainfall and air pressure as well as other factors is a multiple linear regression

2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:

2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4

2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4Next find the Lowest Common Denominator:

No

Step-by-step explanation:

Substitute (6, 10 ) into the left side of the inequality and compare value with right side.

8(6) + 2(10) = 48 + 20 = 68 > 2

SM and MT are the same length

SM = MT

2x+3 = 4x-7

2x-4x = -7-3

-2x = -10

x = -10/(-2)

x = 5

----------

If x = 5, then

SM = 2x+3 = 2(5)+3 = 10+3 = 13

MT = 4x-7 = 4(5)-7 = 20-7 = 13

Both SM and MT are the same length (13 units). This confirms the answer.

Chloe wants to net 50000 on her house. Her closing costs will be 8000 plus 7% commission. She owes 200000 on her loan . What is the minimum contract price that she can accept for the property?

Answers

Answer:

$277,419

Step-by-step explanation:

Relevant Data provided as per the question is

Net amount = 50,000

Closing cost = 8,000

Loan amount = 200,000

Commission percentage = 7%

According to the given situation, the calculation of the minimum contract price is shown below:-

[tex]Minimum\ contract\ price = \frac{(Net\ amount\ +\ Closing\ cost\ +\ Loan\ amount) }{Remaining\ percentage}[/tex]

[tex]= \frac{(50,000 + 8,000 + 200,000)}{(100\% - 7\%)}[/tex]

[tex]= \frac{258,000}{93\%}[/tex]

= $277,419

Therefore for calculating the minimum contract price we simply applied the above formula.


Hadley buys 7 boxes of markers with 8
in each box. Delaney buys 6 boxes of
markers with 12 markers in each box.
How many markers did Hadley and
Delaney buy in all?

Answers

Answer:

128 markers.

Step-by-step explanation:

7 x 8 =  56

12 x 6 = 72

72+ 15 = 87

Hadley and Delaney therefore bought 128 markers all in total.

Hope I helped ! :))))))

The amount of markers Hadley and Delaney bought in all is equal to 128 markers.

Given  the following data:

Hadley = 7 boxes of markers with 8  in each box.Delaney = 6 boxes of  markers with 12 markers in each box.

To determine the amount of markers Hadley and Delaney bought in all:

First of all, we would determine the total number of marker in each box.

For Hadley:

[tex]Hadley = 7 \times 8[/tex]

Hadley = 56 markers

For Delaney:

[tex]Delaney = 6\times 12[/tex]

Delaney = 72 markers

Now, we can find the total markers:

[tex]Total \;markers = Hadley + Delaney\\\\Total \;markers = 56+72[/tex]

Total markers = 128 markers

5. The shape of a dome can be modeled by the equation h = - 2 d 2 + 100 where h is the height (in feet) of the dome from the floor d feet from its center. How far from the center of the dome is the height 50 feet?

6. A cab charges $0.10 per mile and a flat fee of $3.00. Write an equation to model the price y of an x-mile-long cab ride.

7. Use the discriminate to determine the number of solutions to the quadratic equation y = 3 x 2 - 4 x + 6. 8. If f ( x ) = 7 x 2 + 5, compute f ( )3 . 9. Write an equation representing the translation of f ( x ) = 7 x + 3 down 4 units.

Answers

Answer:

5. When the dome is 50 feet high, the distance from the center is 5 feet

6. The equation that model the price y of an x-mile long ride is given as follows;

y = 0.1×x + $3.00

7. The discriminant is < 0; The equation has no real root

8. f(3) = 68

9. The equation representing the translation of the line f(x) = 7·x + 3 down 4 units is f(x) = 7·x + 7

Step-by-step explanation:

5. The given equation for the shape of the dome is presented as follows;

h = -2·d² + 100

Where;

h = The height of the dome (in feet)

d = The distance from the center

Therefore, we have;

When h = 50, d is found as follows;

h = -2·d² + 100

50 = -2·d² + 100

50 - 100 = -2·d²

-50 = -2·d²

∴ 2·d² = 50

d² = 50/2 = 25

d = √25 = 5 feet

Therefore when the dome is 50 feet high, the distance from the center is 5 feet

6. The given rate the cab charges per mile, x = $0.10

The rate the cab charges as flat fee = $3.00

Therefore, the price, y a person traveling by cab for x miles is given by the straight lie equation as y = m·x + c,

Where;

m = the slope or rate which in this case = $0.1/hour

c = A constant term which in this case = $3.00

Therefore

y = 0.1×x + $3.00

The equation that model the price y of an x-mile long ride is y = 0.1×x + $3.00

7. The discriminant, b² - 4·a·c  of the quadratic equation is (-4)² - 4×3×6 = -56

which is < 0, the equation has no real root

8. Given f(x) = 7·x² + 5

f(3) = 7 × (3)² + 5 = 68

f(3) = 68

9. The equation representing the translation of the line f(x) = 7·x + 3 down 4 units is given as follows;

Down 4 units is equivalent to subtracting 4 from the y-coordinate value, therefore, we have;

f(x) - 4= 7·x + 3

f(x) = 7·x + 3 + 4

f(x) = 7·x + 7

The equation representing the translation of the line f(x) = 7·x + 3 down 4 units is f(x) = 7·x + 7

Your question has been heard loud and clear.

M1 = 2kg , M2=2kg , V1=10m/s V2=5m/s

Total momentum before collision = M1V1+M2V2 = 2*10 + 2*5 = 30kgm/s

The test for goodness of fit​ a. ​is always an upper tail test. b. ​is always a two-tailed test. c. ​can be a lower or an upper tail test. d. ​is always a lower tail test.

Answers

Answer: a. ​is always an upper tail test.

Step-by-step explanation:

The chi-square goodness-of-fit test is a test to check whether the sample comes from the population with the expected distribution or not.

If the observed frequency is close to the expected frequency, then the square of the deviations will be small. The square of the deviation is divided by the expected frequency to get the weighted frequencies.

If the sum of these weighted squared deviations is large is then it creates a doubt for the distribution claimed other wise not. Therefore, the chi-square goodness-of-fit test is always a right tail test.

Hence correct option is "a. ​is always an upper tail test. "

Answer:

The point slope formula is : y-y₁ =m(x-x₁), so first u need to find the value of slope.

Step-by-step explanation:

finding the value of slope:

slope(m)= y₂-y₁ ÷ x₂-x₁

              = -1-4 ÷ 2-3

               = 5

now finding equation;

y-y₁=m(x-x₁)

Find all real zeros of the function f(x)= 12 A. 5,7 B. 12 C. 1 D. none

Answers

Answer:

D. None

Step-by-step explanation:

Given the function f(x) = 12, the function is only a constant with no degree. For a function to have roots, it must have at least degree of 1. Let us write the function f(x) = 12 in terms of x

f(x) = 12x⁰

From the function above it can be seen that the introduction of x⁰ can not in any way affect the function of x because x⁰ will return 1.

From the function, it can be seen that the highest power of the variable x is zero. This means that the function has no roots.

Hence, there are no real zeros of the function.
