Answer:
2x + 1/2 sq. ft
Step-by-step explanation:
Surface area = 2(lw+wh+lh)
Given
length l = x ft
width w = 1/2 ft
height h = 1/2ft
Substitute
Surface area = 2(x(1/2)+(1/2)(1/2)+x(1/2))
Surface area = 2(x/2+1/4+x/2)
Surface area = 2(2x/2 + 1/4)
Surface area = 2(x + 1/4)
Surface area = 2x + 2/4
Surface area = 2x + 1/2 sq. ft

Answer:
C. Alternate Interior angles.
Step-by-step explanation:
Alternate interior angles are inside parallel lines, and on opposite sides of the transversal line that crosses the parallel lines.
It's not A, because corresponding angles are in the same position on parallel lines. Angles 2 & 6 are corresponding angles. It's not B, because the two are not next to each other, forming a straight line. 6&7 are straight angles, and 5&6 are straight angles.

Last year, the mean running time for a certain type of light bulb was 8.5 hours. This year, the manufacturer has introduced a change in the production method. A random sample of 40 of the new light bulbs has a mean running time of 8.7 hours with a standard deviation, s, of 0.5 hours. At the 0.05 significance level, test the claim that the mean running time of the new light bulbs is greater than last year’s mean of 8.5 hours. a) State the null and alternative hypotheses symbolically. b) Which test procedure is appropriate to perform the required hypothesis test? c) Compute the value of the test statistic. d) Determine the P-value or provide the rejection region. Please round your answers to three decimal places. e) Should you reject the null hypotheses or not? f) What is your conclusion about the hypothesis test?
Answers
Answer:
H0 : μ = 8.5
H1 : μ > 8.5
1 sample t test ;
Test statistic = 2.53
Pvalue = 0.994
No, we fail to reject the Null ;
There is no significant evidence to support the Claim that the mean running time of light bulb is greater Tha last year.
Step-by-step explanation:
H0 : μ = 8.5
H1 : μ > 8.5
Test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(8.7 - 8.5) ÷ (0.5 / sqrt40)
Test statistic = 2.53
The Pvalue :
P(Z < 2.53) = 0.9943
Pvalue = 0.994
Decison region :
Reject H0 ; if Pvalue < α
0.9943 > 0.05 ; We fail to reject the Null

Find the measure of 2.
Answers
Answer:
115
Step-by-step explanation:
When two parallel lines are intersected by a third line, the angles on both parallel lines are congruent.
Knowing this we can determine that angle 1 is 65 degrees.
Additionally, we know that angle 1 + angle 2 = 180 degrees.
From there we can substitute the measures to determine that 65 + x = 180 and x = 115
In a math class with 19 students, a test was given the same day that an assignment was due. There were 10 students who passed the test and 11 students who completed the assignment. There were 6 students who failed the test and also did not complete the assignment. What is the probability that a student chosen randomly from the class passed the test and completed the homework?
Answers
Answer:
8/19
Step-by-step explanation:
The probability that a student is chosen randomly from the class passed the test and completed the homework will be 0.1637.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
In a math class with 19 students, a test was given the same day that an assignment was due.
There were 10 students who passed the test and 11 students who completed the assignment.
There were 6 students who failed the test and also did not complete the assignment.
Then the probability that a student is chosen randomly from the class passed the test and completed the homework will be
The number of the student who has done at least one assignment or passed the test is 19 - 6 = 13
n(A) = passes student
n(B) = given assignment
Then we have
[tex]\rm n(A \cap B) = n(A) + n(B) - n(A \cup B) \\\\n(A \cap B) = 10 + 11 - 13\\\\n(A \cap B) = 8[/tex]
Then the probability will be
[tex]\rm P = \dfrac{^8C_2}{^{19}C_2}\\\\P = \dfrac{28}{171}\\\\P = 0.1637[/tex]

1. draw a box around the point that representa the foot with length closest to 29cm.
2. what is the approximate width of the foot.
3 what width does the model predict for a foot with length 29cm.
Answers
a) The box is drawn on the scatter plot.
b) The approximate width of 29 cm foot length is 10 cm.
c) The model predicts the foot width of 10.3 cm for 29 cm foot length.
What is the scatter plot?
A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.
The scatter plot for relationship between foot length and width is given.
In the scatter plot the x axis represents the foot length in cm.
In the scatter plot the y axis represents the width length in cm.
A box is drawn around the data which represents the foot with length closest to 29 cm.
The approximate width for 29 cm foot length is the y-intercept corresponding to x = 29 cm.
Here, the y intercept is obtained as 10 cm.
On seeing the scatter plot it is obtained that the model predicts the values as 10.3 cm as width for 29 cm foot length.
Therefore, the intercept point is obtained as (29,10.3).

Help this type of work confuses me
Answers
Answer/Step-by-step explanation:
Given:
-x + 3x + 1 + 4(x + 2) = 54
To solve, first open the bracket by applying the distributive property. Multiply every term you have in the bracket by 4
-x + 3x + 1 + 4x + 8 = 54
Add like terms together
6x + 9 = 54
Subtract 9 from each side
6x = 54 - 9
6x = 45
Divide both sides by 6
x = 45/6
x = 7.5

Answer:
A. Event A is not dependent on Event B.
Step-by-step explanation:
You have two events A and B such that P(A| B) = 0.4 and P(A) = 0.4.
This means that the probability of event A happening, given that B happened is 0.4, which is also the same probability of event A happening.
Since these probabilities are equal, event A is independent from option B, and the correct answer is given by option A.
