Find the area of the shaded region where a = -1.88 and b = 2.12. Note: the graph may not be drawn to scale. Write only a number as your answer. Round to 4 decimal places (for example 0.6148). Do not write as a percentage. (picture in attachment)
Answer:
0.0471
Step-by-step explanation:
Here, we want to find the area of the shaded region.
The area of the shade region = 1- area of the unshaded region
The area of the unshaded region is as follows;
P(b) - P(a)
and that is;
P(-1.88<x<2.12) = 0.95294 from z table
So the area of the shaded region = 1-0.95294 =
0.04706 = 0.0471 to 4 d.p
Help!! Is there any way I could calculate this on a graphing calculator or do I have to do it by hand?
Answer:
you can graph the points. i recommend using Desmos
Step-by-step explanation:
As for the line of best fit you can use snaggit or snipping tool and both can help with the graph.
for the residual, you need to calculate the actual value minus the predicted value.
you should be given a formula in your problem.... that is for the predicted value.
Hope this helps!!
Answer:
go ahead and graph the points
Jordan is calculating the slope of the trend line in the scatterplot below. On a coordinate plane, a trend line has a positive slope. How can Jordan use the plot to check the reasonableness of his answer? His slope should be positive because the coordinates of all the plotted points are positive. His slope should be positive because the trend line is slanted up to the right. His slope should be negative because there are plotted points not on the line. His slope should be negative because the x-coordinate of each plotted point is less than the y-coordinate.
Answer:
His slope should be positive because the trend line is slanted up to the right.
Step-by-step explanation:
Assume the graph is like the one below.
The line is slanted up and to the right, so the slope is positive.
A is wrong. The points could all be positive and have a negative slope.
C is wrong. Most of the points are not on the line but the slope is still positive.
D is wrong. The slope does not depend on the values of x and y. It depends on the values of Δx and Δy.
Answer:
Step-by-step His slope should be positive because the trend line is slanted up to the right.

Expected Value (50 points) Game: Roll two dice. Win a prize based on the sum of the dice. Cost of playing the game: $1 Prizes: Win $10 if your sum is odd. Win $5 if you roll a sum of 4 or 8. Win $50 if you roll a sum of 2 or 12. Explain HOW to find the expected value of playing this game. What is the expected value of playing this game? Show your work. (30 points)
Answer:
$7.89
Step-by-step explanation:
There are 36 possible outcomes when rolling two dice.
The sum will be odd if the first die is odd and the second is even or if the second is odd and the first is even. The probability of an odd sum is:
[tex]P(odd)=\frac{3}{6} *\frac{3}{6} +\frac{3}{6} *\frac{3}{6}\\P(odd)=0.5[/tex]
There is a probability of 1 in 2 of winning $10.
There are 8 ways to get a sum of 4 or 8 (1,3; 3,1; 2,2; 5,3; 3,5; 2,6; 6,2; 4,4). There is a probability of 8 in 36 or 2 in 9 of winning $5.
There are 2 ways to get a sum of 2 or 12 (1,1; 6,6). There is a probability of 2 in 36 or 1 in 18 of winning $50.
Any other outcome will not payout any amount.
The expected value is the sum of all possible payouts multiplied by their likelihood (including a 100% chance of paying $1 to play).
[tex]E=-1+10*\frac{1}{2} +5*\frac{2}{9}+50*\frac{1}{18}\\E=\$7.89[/tex]
The expected value is $7.89.

Answer:
the angle itself is 39
Step-by-step explanation:
first the angle 132 is apart of line segment jer so 180-132=48
48+93=141
180-141=39
Answer:
39º
Step-by-step explanation:
Once the angle 132º and angle ∠BER are supplementary angles (add up to 180 degrees), ∠BER = 48º.
Also, once the sum of a triangle's interior angles is 180º:
∠BER + 93º + (9x+3)º = 180º
48º + 93º + 9x + 3º = 180º
144º + 9x = 180º
9x = 36º
x = 4º
Therefore, the angle ∠EBR (green) is equal to 39º

There is a bag with only red marbles and blue marbles. The probability of randomly choosing a red marble is 1/8. There are 56 marbles in the bag and each is equally likely to be chosen. Work out how many red marbles there must be
Answer:
7 red marbles
Step-by-step explanation:
P( red) = red marbles / total marbles = 1/8
We know there are 56 marbles
red marbles/56 = 1/8
Multiply by 56
red marbles = 1/8 *56 = 7
There are 7 red marbles
Read the excerpt from A Vindication of the Rights of Woman. Let there be then no coercion established in society, and the common law of gravity prevailing, the sexes will fall into their proper places. And, now that more equitable laws are forming your citizens, marriage may become more sacred: your young men may choose wives from motives of affection, and your maidens allow love to root out vanity. What is the central idea of the excerpt? In proper societies, there are strict laws about marriage. Men will fall into submission when their wives are well educated. In equal roles, men and women will establish more meaningful marriages. Men and women should marry for reasons other than love and affection.
Answer:
In equal roles, men and women will establish more meaningful marriages.
Step-by-step explanation:
Marry Wollstonecraft in her feminist philosophy "A Vindication of the Rights of Woman" had projected the idea of equalizing the rights of men and women. She builds her argument against the theorists who do not consider education to be important for the female gender of the society. She presents her point by giving instances of how the education of women is indirectly related to the upliftment of the entire society. Wollstonecraft urges for equal fundamental rights to be shared by both men and women. An educated woman not just helps to become a good 'companion' of her husband but also raises her children in an efficient way.
maddy had twice as many stamps as simon. After maddy sold 60 stamps, simon had twice as many stamps as maddy. how many more stamps did maddy have than simon in the beginning
Answer: 40 stamps
Step-by-step explanation:
Let Maddy = M and Simon = S
Given that maddy had twice as many stamps as simon. That is,
M = 2S ....(1)
After maddy sold 60 stamps, simon had twice as many stamps as maddy. That is,
S = 2( M - 60) .... (2)
Substitutes M for 2S from equation (1) into equation (2)
S = 2( 2S - 60 )
Open the bracket
S = 4S - 120
Collect the like terms
S - 4S = -120
- 3S = - 120
S = 120/3
S = 40
Substitute S into the equation (1)
M = 2 × 40 = 80
Maddy has 80 - 40 = 40 stamp
Therefore, Maddy has 40 more stamps than simon in the beginning.

Tim wants to build a rectangular fence around his yard. He has 42 feet of fencing. If he wants the length to be twice the width, what is the largest possible length? Write an equation and solve.
Answer:
Rectangular fence dimensions:
x = 14 ft
w = 7 ft
A = 98 ft²
Step-by-step explanation:
Rectangular fence dimensions:
x length and w width
Then x = 2*w ⇒ w = x/2
Perimeter is
p = 2*x + 2*w
p = 2*x + 2* x/2
p = 2*x + x
3*x = 42
x = 14 ft and w = 14/2 ⇒ w = 7 ft
Julio’s rotation maps point K(–6, 9) to K’(9, 6). Which describes the rotation? A. 90 degrees clockwise rotation B. 180 degrees rotation C. 90 degrees counterclockwise rotation D. 270 degrees clockwise rotation
Answer:
The correct option is;
A. 90 degrees clockwise rotation
Step-by-step explanation:
From the given information, we have;
The coordinates of the pre-image is K(-6, 9)
The coordinates of the image is k'(9, 6) which is similar to a transformation of a pre-image of (x, y) to an image of (y, -x)
The transformation from (x, y) to (y, -x) can be obtained from either;
1) A rotation of 90° (clock wise)
2) A rotation of 270° counter clockwise
Therefore, the correct option that maps K(-6, 9) to K'(9, 6) is a 90 degrees clockwise rotation.
Answer: The person above me is correct! A. 90 degrees clockwise rotation

Andrew scored 16 points at basketball tonight. If he keeps scoring this many points every game for the 14-game season, how many points will he score in total?
Answer:
224 points.
Step-by-Step Explanation:
We know that Andrew scores 16 points per basketball game.
He continues scoring the same amount of points for 14 more games.
Therefore, the total amount of points he will score in total will be 16 multiplied by 14.
Since 16 times 14 is 224, this means that Andrew will score 224 points in total.

Brian plays basketball. In the past he has made 4 out of every 5 free throws. What is the probability, as a decimal, that Brian will make the next two free throws?
Answer:
0.64
Step-by-step explanation:
4 out of 5 free throws is 0.8 as a decimal.
The probability that Brian will make 2 free throws is 0.8 for the first one, and then 0.8 of that for the second one. That means you multiply the two to get your answer and 0.8 times 0.8 = 0.64.

Bill drives 2 hours at a speed of 60 mph (miles per hour). Afterwards, he drives for 4 hours at a speed of 75 mph. What is his average
speed over the 6 hours that he spent driving
Answer:
70 mph
Step-by-step explanation:
Here we want to calculate average speed
Mathematically, average speed = Total distance/Total time
Kindly recall distance = speed * time
for the first part;
We have: 60 * 2 = 120 miles
For the second: 4 * 75 = 300 miles
Average speed = (300 + 120)/(4 + 2) = 420/6 = 70 mph
What is the measure of angle A?
Answer:
38 degrees
Step-by-step explanation:
The angle can be found using the Law of Cosines:
a² = b² +c² -2bc·cos(A)
cos(A) = (b² +c² -a²)/(2bc) = (3² +7² -5²)/(2·3·7) = 33/42
A = arccos(33/42) ≈ 38.213°
The measure of angle A is about 38°.
