(B Fail to reject the null hypothesis. The P-value is greater than the level of significance.
What is the null hypothesis?The null hypothesis is a common arithmetic theory that asserts that no statistical relationship or significance exists between two sets of observed data and measured phenomena in a set of given, single, observed variables.
The null hypothesis is rejected, if the P-value is less than the level of significance.
Here, it is provided that the test is left-tailed and the z score is -1.23.
From, the table of the negative scores, the P-value for the left-tailed test is 0.1093.
Since the P-value (0.1093) is greater than the level of significance (0.05). The null hypothesis is not rejected.
Hence, the correct option is (B), Failing to reject the null hypothesis. The P-value is greater than the level of significance.

Joanne cannot decide which of two washing machines to buy. The selling price of each is $520. The first is marked down by 50%. The second is marked down by 20% with an additional 30% off. Find the sale price of each washing machine. Use pencil and paper. Explain why Joanne should buy the first washing machine rather than the second if the machines are the same except for the selling price. Question content area bottom Part 1 The sale price of the first washing machine is $enter your response here . (Round to the nearest dollar as needed.)
Answer:
The first washing machine is 50% off- so it'd be $260 for the final price
The second washing machine was marked down by 20%, so it'd be 416. But then it was marked down another 30% so the final price would be $291
Since the first washing machine was just 50% of $520, it's a better deal rather than 20% of $520, then 30% of $416
I hope my answer was clear enough!
At the movies, a couple bought 2 medium drinks and a large popcorn for $13.85. At the same theater, a family bought 3 medium drinks and 2 large popcorns for a total of $23.90. What is the cost of a medium drink and a large popcorn?
Answer:
cost of one medium drink = $3.80
cost of one large popcorn = $6.25
Step-by-step explanation:
Let D = cost of one medium drink
Let P = cost of one large popcorn
If a couple bought 2 medium drinks and a large popcorn for $13.85:
⇒ 2D + P = 13.85
If a family bought 3 medium drinks and 2 large popcorn for a total of $23.90:
⇒ 3D + 2P = 23.90
Rewrite 2D + P = 13.85 to make P the subject:
⇒ P = 13.85 - 2D
Substitute into 3D + 2P = 23.90 and solve for D:
⇒ 3D + 2(13.85 - 2D) = 23.90
⇒ 3D + 27.7 - 4D = 23.90
⇒ D = 3.8
Substitute found value of D into P = 13.85 - 2D to find P:
⇒ P = 13.85 - (2 x 3.8) = 6.25
Therefore,
cost of one medium drink = $3.80
cost of one large popcorn = $6.25

What is the measure of ∠x , in degrees, in the figure shown?
Answer:
113
Step-by-step explanation:
180-22-45=113 umm just subtract
The measure of ∠x is 67 degrees.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
By angle sum property we find the measure of ∠x
We have to find the adjacent angle of x to find value of x
22+45+X=180
67+X=180
Subtract 67 from both sides
X=180-67
X=113
We know that sum of adjacent angles is 180 degrees.
X+x=180
x=180-113
x= 67 degrees.
Hence, the measure of ∠x is 67 degrees.

A triangle labeled ABC with angle A as one hundred twenty degrees, angle B as X degrees and angle C as parenthesis X plus sixteen parenthesis degrees
Answer:
m∠B=22°
Step-by-step explanation:
All angles in a triangle add up to 180 degrees
Knowing this, we now understand:
∠A+∠B+∠C=180°
Let's substitute!
(120)+(x+16)+(x)=180
120+x+16+x=180
136+2x=180

The selling price of washing machine = Rs. 13500
Loss percent = 20%

Step-by-step explanation:
the area of the simpsons new house is 150% of the area of the old house. Write this percentage as a fraction and as a decimal
150% can be written as a decimal as 1.5
150% can be written as a fraction of 3/2.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
150%
This can be written as:
Fraction:
= 150%
= 150/100
= 15/10
= 3/2
Decimal:
= 150%
= 150/100
= 15/10
= 1.5
Thus,
150% = 3/2
150% = 1.5

≥ - greater than or equal to
The correct inequality that represents Priya's number of books is x ≥ 25
How to determine the inequality?From the question, we understand that:
Only those who read at least 25 books are invited
At least in inequality means "greater than or equal to"
This means that students who read the number of books greater than or equal to 25 were invited
Priya's number of books is x

The scatter plot below shows the relationship between the age of a house and the number of days it takes for the house to be sold after being listed for sale.
The equation y = 0.95x + 17.56 describes the line of best fit for the scatter plot. Based on the equation, which value is most likely the number of days it takes for a 60-year-old house to be sold after being listed for sale?
A. 45
B. 70
C. 75
D. 83
Put 60 as x and get no of days .
y=0.95x+17.56y=0.95(60)+17.56y=57+17.56y=74.56y=75daysOption C
Answer:
C. 75
Step-by-step explanation:
The scatter plot shows a positive correlation since the y-value increases as the x-value increases.
Given equation of the line of best fit:
y = 0.95x + 17.56
To estimate the number of days it takes for a 60-year-old house to be sold, input x = 60 into the given equation:
⇒ y = 0.95(60) + 17.56
⇒ y = 57 + 17.56
⇒ y = 74.56
⇒ y = 75 (nearest whole day)
Therefore, according to the line of best fit, an estimate of the number of days it will take for a 60-year-old house to be sold is 75 days.
Extrapolation
For this problem, we have used the line of best fit (regression line) to predict a value of that is outside the range of the original data. When using values of x outside the range to predict corresponding values of y, this is called extrapolation. These predictions can be unreliable because there is no evidence that the relationship described by the regression line is true for all values of x. Therefore, caution should be applied in these cases.

A builder installs 2 rose windows and 2 tulip windows. Write and evaluate an expression to find the combined area of the windows.
Answer:
The expression for the combined areas of the window will be
(2x3^2x30) + 2x4^2x33
The total cost for the builder is $1596
Step-by-step explanation:
Cost of a window = area of window in square feet x price per square foot.
So, using this, we can find cost of n number of windows.
The cost of two rose windows is 2 x 3^2 x 30
The cost of two tulip windows is 2 x 4^2 x 33
The total cost is ( 2 x 3^2 x 30 ) + ( 2 x 4^2 x 33 )
By using the order of operations,
(2 x 3^2 x 30) + (2 x 4^2 x 33)
= ( 2 x 9 x 30 ) + ( 2 x 16 x 33 )
= (18 x 30 ) + (32 x 33)
= 1596

Answer:
The theoretical probability is that it will be Heads Heads 25% of the time. However, the experimental probability is 10%.
Step-by-step explanation:
The main difference between experimental and theoretical probability is that experimental probability is based on the actual results of an experiment. In contrast, the theoretical probability is based on possible outcomes based on assumptions.
