Two sides of a quadrilateral have the same length, x, while
the other two sides have the same length, both being the next
consecutive odd integer. Write the sum of these lengths. Then
simplify this expression.
?
Answer:
Step-by-step explanation:
It sounds as though x is odd. The other two sides have length x+2. Perimeter of quadrilateral = 2x + 2(x+2) = 4x + 4

Solve the difference of 9x and 8x is 107
Answer:
x = 107
Step-by-step explanation:
If x = 107,
(9 x 107) - (8 x 107) = 107
Then x must be 107.
A researcher is interested in estimating the mean weight of a semi tracker tractor truck to determine the potential load capacity. She takes a random sample of 17 trucks and computes a sample mean of 20,000 pounds with sample standard deviation of 1,500. The 95% confidence interval for the population mean weight of a semi tracker tractor truck is ______________.
Answer:
(19228.737 ; 20771.263)
Step-by-step explanation:
Given that:
Sample size, n = 17
Sample mean, m = 20,000
Sample standard deviation, s = 1500
α = 95%
The confidence interval,
Mean ± margin of error
Margin of Error : Tcritical * s/sqrt(n)
Tcritical at α = 0.05 ; df = n-1 = 17 - 1 = 16 ; 2 - tailed test = 2.120
Margin of Error = 2.120 * 1500/sqrt(17) = 771.263
Lower boundary :
20,000 - 771.263 = 19228.737
Upper boundary :
20,000 + 771.263 = 20771.263
Confidence interval :
(19228.737 ; 20771.263)

Answer:
The area would be 40.5 cm ^2
Step-by-step explanation:
Well first you don’t gotta worry about some isosceles trapezoid thingy.
You just gotta know the formula for a trapezoid is (b1+b2)/2)h
B1 in this case is or base 1 (9 or 4.5)
b2 in this case is or base 2 (9 or 4.5)
(you can only choose one base for each)
ANd you add those 2 up and you’d get 13.5
13.5/2 which is 6.75
Now we multiply it by the height which is 6 and gte 40.5
40.5cm ^2 is the final answer
At a food truck, 1/8 of a whole pizza costs $2. In an hour, 6 ¼ pizzas were sold. How much money was made at the food booth in that hour?
9514 1404 393
Answer:
$100
Step-by-step explanation:
We assume you're interested in the revenue collected by the food truck.
6 1/4 pizzas = (6·4+1)/4 = 25/4 = 50/8 pizzas = 50×(1/8 pizza)
If each 1/8 pizza slice is sold for $2, then the revenue is ...
50 × $2 = $100 . . . . revenue from 6 1/4 pizzas

Complete the equation of the line through (1,4) and (2,2)
Use exact numbers.
y=?
Step-by-step explanation:
slope = 2-4/2-1 = -2
y - 2 = -2(x - 2)
y-2 = -2x +4
y = -2x + 6
Answer:
y = -2x + 6
Step-by-step explanation:
(y-4)/(2-4) = (x-1)/(2-1)
(y-4)/(-2) = x-1
y-4 = -2x +2
y = -2x + 6

Let 2_3/4 be 11/4.
We now have 2/5 * 11/4.
(numerator times numerator)/(denominator times denominator).
(2 * 11)/(5 * 4)
22/20
We can now reduce this fraction to the lowest terms.
The greatest factor of 22 and 20 is 2.
22 divided by 2 = 11.
20 divided by 2 = 10.

Measuring the height of a tree is usually more difficult than measuring the diameter of the tree. Therefore, many researchers use regression models to predict the height of a tree from its diameter measured at 4 feet 6 inches from the ground. The following computer output shows the results of a linear regression based on the heights, in feet, and the diameters in inches, recorded from 31 felled trees.
Estimate Std Error t-value Pr(>|t|)

(C) (0.423,1.685).
(D) (0.732. 1.376).
(E) (53.07.70.99).
Answer:
(B) (0.396, 1.712)
Step-by-step explanation:
From the information given;
Confidence Interval = 0.95
Significance Level [tex]= 1 - 0.95 = 0.05[/tex]
The confidence interval for regression coefficient beta (whereby in this case it is the coefficient of the diameter) is expressed by:
= [tex]( Beta ^- \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ), Beta^+ \ t_{n-2}, \alpha/2 ( S.E \ of \ \^ \ \ ))[/tex]
From the regression coefficient, the estimated value of beta^ = 1.054
[tex]= (1.054 - t_{29,0.025} *(0.322), 1.054 + t_{29,0.025}*(0.322))[/tex]

a tank containing 2.85 cube of oil how many bottles of 300 ml capacity can be filled out of it
Answer:
9,500 bottles.
Step-by-step explanation:
1 cubic meter = 1000000 milli liters
We can convert (2.85 cubic meter) to (milli liters) as
1 cubic meter = 1000000 milli liters
2.85 cubic meter = X milli liters
If we Cross multiply and find X, we have
X milli liters = [(2.85 cubic meter × 1000000 milli liters) ] / 1 cubic meter
X= 2850,000 milli liters
Then (2.85 cubic meter) will be equal to ( 2850,000 milli liters)
Capacity of the Bottle = 300 ml
Number of bottles that 300 ml capacity can be filled out of it =
(2850,000 milli liters) / (300 ml)
= 9,500 bottles.
You are conducting a significance test of H0: μ = 5 against Ha: μ > 5. After checking the conditions are met from a simple random sample of 30 observations, you obtain t = 2.35. Based on this result, describe the p-value.
The p-value falls between 0.15 and 0.2.
The p-value falls between 0.025 and 0.05.
The p-value falls between 0.01 and 0.02.
The p-value falls between 0.005 and 0.01.
The p-value is less than 0.005.
Answer:
The p-value falls between 0.005 and 0.01.
Step-by-step explanation:
Random sample of 30 observations, you obtain t = 2.35
This means that the pvalue is 1 subtracted by the pvalue of Z = 2.35, as we are testing that the mean is more than a value.
Looking at the z-table, z = 2.35 has a pvalue of 0.9906
1 - 0.9906 = 0.0094
So, between 0.005 and 0.01.
Answer: The p-value falls between 0.01 and 0.02.

Step-by-step explanation:
During an economic downturn, 11 companies were sampled and asked whether they were planning to increase their workforce. Only 2 of the 11 companies were planning to increase their workforce. Use the small-sample method to construct an 80% confidence interval for the proportion of companies that are planning to increase their workforce. Round the answers to at least three decimal places.
An 80% confidence interval for the proportion of companies that are planning to increase their workforce is _______ < p< ________
Answer:
An 80% confidence interval for the proportion of companies that are planning to increase their workforce is 0.033 < p < 0.331.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
Only 2 of the 11 companies were planning to increase their workforce
This means that [tex]n = 11, \pi = \frac{2}{11} = 0.182[/tex]
80% confidence level
So [tex]\alpha = 0.2[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.2}{2} = 0.9[/tex], so [tex]Z = 1.28[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.182 - 1.28\sqrt{\frac{0.182*0.818}{11}} = 0.033[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.182 + 1.28\sqrt{\frac{0.182*0.818}{11}} = 0.331[/tex]
An 80% confidence interval for the proportion of companies that are planning to increase their workforce is 0.033 < p < 0.331.
