Solve for u. -9–4u=-u

Answer: Model B

Step-by-step explanation: Model B, shows the cutting of 40%  of the ribbon since, if you divide it into 10 parts, with each piece representing 10%, if you take away 4 of those parts, which is equal to 40%. So it is Model B.

Answer:

answer  is 189.43

Step-by-step explanation:

Answer: 180.6 cm2

Step-by-step explanation:

B = base = 7 cm

S = slant height = 9.4 cm

Formula: Surface area = b(*powered) + 2bs

Step by step:

7(7) + 2(7)(9.4) =

49 + 2(65.8) =

49 + 131.6 =

180.6 cm2

Answer:

First box (Top left): y + x = 4

Second box (Top right): y = x + 4

Third box (Bottom): y = (1/4)x

Step-by-step explanation: For the first box on the top left, the line is shown going down which means as x increases, y decreases resulting in a negative slope. Since the equation of a line has the form y = mx + b where m represents the slope, m would be a negative number for a negative slope. By rearranging the equations above, we can write y + x = 4 as y = -x + 4 after subtracting both sides by -x to make it look like the form y = mx + b. Since this is the only equation with a negative slope and the y-intercept (where the line intercepts the y-axis) represented as b is 4 as shown in the graph and the equation, the equation for this line is y + x = 4.

For the second box on the top right, the line is shown going up which means as x increases, y increases resulting in a positive slope. Since the slope is now positive, the m, in the same form, y = mx + b, would be a positive number. The y-intercept or b is also still 4 as shown in the graph as the line intersects the y-axis so by looking at the options above, the equation for this line is y = x + 4.

For the third box on the bottom, the line is shown with a less steep slope going up meaning as x increases, y increases with a lower slope. Since the slope will still be positive but lower than the previous line with a y-intercept of 0 as shown in the graph, the equation for this line is y = (1/4)x.

To compare the probabilities of hitting the ball, we need to find the decimal equivalent of each fraction.

Player 1: 7/11 = 0.636

Player 2: 6/9 = 0.667

Player 3: 5/7 = 0.714

Comparing the probabilities, we can see that Player 3 has the highest probability of hitting the ball, followed by Player 2 and then Player 1. So the correct statement is:

Player 3 is more likely to hit the ball than Player 2 because P(Player 3) > P(Player 2), and Player 2 is more likely to hit the ball than Player 1 because P(Player 2) > P(Player 1).

It's important to note that the probabilities don't guarantee that a player will hit the ball every time they're at bat. They simply indicate the likelihood of hitting the ball based on their past performance.

Answer:

median is 25, max value is 24, but check IQR and range

Answer:

Option 1

Option 2

Option 4

Only incorrect answer is that of Option 3

Step-by-step explanation:

This is slightly tricky because the value of the first quartile and that of the third quartile have to be estimated roughly since more accurate units on the scale are not provided. One can only say that Q1 lies between 10 and 15, Q3 lies between 35 and 40

I estimate Q3 as 38 and Q1 as 12(I could be off base here) which gives the Inter Quartile Range IQR = Q3 - Q! = 38 - 12 =26

If your previous attempts have indicated this answer as incorrect you should not choose it. However IQR is close to 26 so that is my best estimate and I would state Option 1 as correct

Option 2 is correct - you can see that the last vertical line which is the end of the right whisker is at 44

Option 3 is wrong - The maximum value is 44, minimum value is positive at about 2  (tail of left whisker so range cannot be 50. Estimate is 44- 2 = 42

Option 4 is correct:
The median marks the mid-point of the data and is shown by the line that divides the box into two parts (sometimes known as the second quartile). Half the scores are greater than or equal to this value, and half are less.

This line is at 25 so the median is 25

I hope that was useful and you get it correct.

Answer:A

Step-by-step explanation:100-18=82 in percentages convert that to fractions and you have 0.82 x whatever he earned at first (x) becauss we are dealing with percentages here

Makayla bought stock in a company two years ago that was worth x dollars. During the first year that she owned the stock, it increased by 12%. During the second year, the value of the stock decreased by 7%. The value of the stock in terms of x after two years have passed is 1.0416x dollars.

Value of stock = x dollars

During 1st year, increase in stock = 12%

Therefore, the value of stock becomes = [tex]\frac{12}{100}[/tex] × (x) + x

                                                                 = 0.12x + x = 1.12x

During 2nd year, decrease in stock = 7%

Therefore, the value of stock becomes = 1.12x - [tex]\frac{7}{100}[/tex] ×1.12x

                                                                 = 1.12x - 0.0784x = 1.0416x

So, the value of the stock in terms of x after two years have passed is 1.0416x dollars.
