Answer: step 3 is the correct first step

Step-by-step explanation:

Let us number the steps

1) Tyreese’s first step is to

remove one x-tile from both sides.

2) remove two x-tiles from the left side.

3) add one positive x-tile to both sides.

4) add two positive x-tiles to both sides.

The equation which Tyreese wants to solve is

2x + 5 = - x + ( -1 ). The aim is to make x to be on only one side

1) If she applies step 1, it becomes

2x - x + 5 = - x - x + ( -1 )

x + 5 = -2x - 1

x is still on both sides, so step 1 is wrong.

2) If she applies step 2, it becomes

2x - 2x + 5 = - x + ( -1 )

5 = -x - 1

step 2 is wrong because whatever you do to the left hand side must also be done to the right hand side. So 2x must be removed from both sides.

3) If she applies step 3, it becomes

2x +x + 5 = - x + x + ( -1 )

3x + 5 = - 1

x is on only the left hand side of the equation, so step 3 is right.

4) If she applies step 4, it becomes

2x + 2x + 5 = - x + 2x + ( -1 )

4x + 5 = x - 1

x is still on both sides, so step 4 is wrong.

Answer:

add one positive x-tile to both sides.

Step-by-step explanation:

3) If she applies to step 3, it becomes

2x +x + 5 = - x + x + ( -1 )

3x + 5 = - 1

x is on only the left-hand side of the equation, so step 3 is right.

Consider the provided equation.

2x + 5 = -x + 1

Now to solve the above equation first isolate the variables.

To isolate the variables add x to both the side of the equation.

2x + 5 + x = -x + 1 + x

Now add the like terms.

3x + 5 =  1

Here we add the x tiles to both the side of the equation.

Find the shaded angle
masya89 [10]

Answer:

332°

Step-by-step explanation:

Given is an isosceles triangle,

Measures of base angles of an isosceles triangle are equal.

Therefore,

Measure of central angle

= 180° - ( 76° + 76°)

= 180° - 152°

= 28°

Measure of shaded angle

= 360° - 28°

= 332°

A player of the National Basketball Association’s Portland Trail Blazers is the best free-throw shooter on the team, making 94%
g100num [7]

Answer:

The data for the probabilities are shown in the table below.

- A represents the probability of making the two shots for each of the best and worst shooter on the Portland Trail Blazers' team

- B represents the probability of making at least one shot for each of the best and worst shooter on the Portland Trail Blazers' team.

- C represents the probability of not making any of the two shots for each of the best and worst shooter on the Portland Trail Blazers' team.

N | Best ||| Worst

A | 0.8836 | 0.3136

B | 0.9964 | 0.8064

C | 0.0036 | 0.1936

It becomes evident why fouling the worst shooter on the team is a better tactic. The probabilities of the best shooter making the basket over the range of those two free shots are way better than the chances for the worst shooter.

Step-by-step explanation:

Part 1

Probability of the best shooter of the National Basketball Association’s Portland Trail Blazers making a shot = P(B) = 94% = 0.94

Probability that he doesn't make a shot = P(B') = 1 - 0.94 = 0.06

a) Probability that the best shooter on the team makes the two shots awarded = P(B) × P(B) = 0.94 × 0.94 = 0.8836

b) Probability that the best shooter on the team makes at least one shot.

This is a sum of probabilities that he makes only one shot and that he makes two shots.

Probability that he makes only one shot

= P(B) × P(B') + P(B') + P(B)

= (0.94 × 0.06) + (0.06 × 0.94) = 0.1128

Probability that he makes two shots = 0.8836 (already calculated in part a)

Probability that he makes at least one shot = 0.1128 + 0.8836 = 0.9964

c) Probability that the best shooter on the team makes none of the two shots = P(B') × P(B') = 0.06 × 0.06 = 0.0036

d) If the worst shooter on the team, whose success rate is 56% is now fouled to take the two shots.

Probability of the worst shooter on the team making a shot = P(W) = 56% = 0.56

Probability that the worst shooter on the team misses a shot = P(W') = 1 - 0.56 = 0.44

Part 2

a) Probability that the worst shooter on the team makes the two shots = P(W) × P(W)

= 0.56 × 0.56 = 0.3136

b) Probability that the worst shooter on the team makes at least one shot.

This is a sum of probabilities that he makes only one shot and that he makes two shots.

Probability that he makes only one shot

= P(W) × P(W') + P(W') + P(W)

= (0.56 × 0.44) + (0.44 × 0.56) = 0.4928

Probability that he makes two shots = 0.3136 (already calculated in part a)

Probability that he makes at least one shot = 0.4928 + 0.3136 = 0.8064

c) Probability that the worst shooter makes none of the two shots = P(W') × P(W') = 0.06 × 0.06 = 0.1936

From the probabilities obtained

N | Best ||| Worst

A | 0.8836 | 0.3136

B | 0.9964 | 0.8064

C | 0.0036 | 0.1936

It becomes evident why fouling the worst shooter on the team is a better tactic. The probabilities of the best shooter making the basket over the range of those two free shots are way better than the chances for the worst shooter.

Shenise is a star player for her women's basketball team. She has injured her ankle, and it is doubtful that she will be able to
Sladkaya [172]

Answer:

<u>The correct answer is that it's expected the team will score 72 points.</u>

Step-by-step explanation:

1. This is the information given in the question:

When Shenise can play the team scores 91 points

Without Shenise the team just scores 60 points

Therefore, when Shenise is at her best, her 100%, she scores 31 points by herself. When she's not in conditions, she can't play.

2. For finding out how many points Shenise can score if she plays, we use this formula:

If Shenise is at her 100%, she scores 31 points, how many points can she score if she's at 40% chance of playing?

Points upcoming game = 31 * 40 / 100

Points upcoming game = 1,240 / 100

Points upcoming game = 12.40 = 12 (rounding to the nearest whole number)

3. If Shenise plays, she can score 12 points. Now, we can calculate how many points her team will score.

Points the team scores when Shenise doesn't play = 60

Points the team will score if Shenise plays = 60 + 12 = 72

<u>The team will probably score 72 points with a 40% chance that Shenise will play the upcoming game</u>
