Let event A = "math test" and event B = "Score: 90-100." Then find , where

Answers

To find the percentage of students who took the math test and received a grade of 90 or above, we need to calculate the conditional probability P(A ∩ B), which is the probability of event A ("math test") and event B ("Score: 90-100") happening simultaneously.

From the two-way frequency table:

The number of students who took the math test and received a grade of 90 or above is 20.

The total number of students who took the math test is 20 + 40 + 7 = 67.

Now, we can calculate the conditional probability:

P(A ∩ B) = (Number of students who took the math test and received a grade of 90 or above) / (Total number of students who took the math test) × 100%

P(A ∩ B) = 20 / 67 × 100% ≈ 29.85%

So, the percentage of students who took the math test and received a grade of 90 or above is approximately 29.85%.

Step-by-step explanation:

Find x of this shape.

Answers

Answer:

x = 9

Step-by-step explanation:

M is at the midpoint of GA and N is at the midpoint of HA, hence

MN is a mid-line segment and is half the length of GH, that is

5x = (1)/(2)(15x - 45) ← multiply both sides by 2

10x = 15x - 45 ( subtract 15x from both sides )

- 5x = - 45 ( divide both sides by - 5 )

x = 9

Solve for y: R (6x-11)° (9y-19)° (4x+23)°​

Answers

Answer:

y = 12

Step-by-step explanation:

We first need to solve for x

(6x - 11)° and (4x + 23)° are vertically opposite angles and are congruent, so

6x - 11 = 4x + 23 ( subtract 4x from both sides )

6x - 4x - 11 = 4x - 4x + 23 ( simplify both sides )

2x - 11 = 23 ( add 11 to both sides )

2x - 11 + 11 = 23 + 11 ( simplify both sides )

2x = 34 ( divide both sides by 2 )

(2)/(2) x = (34)/(2) , that is

x = 17

Then

4x + 23 = 4(17) + 23 = 68 + 23 = 91

(9y - 19)° and 91 are a linear pair and sum to 180°

sum the 2 angles and equate to 180

9y - 19 + 91 = 180 ( simplify left side )

9y + 72 = 180 ( subtract 72 from both sides )

9y + 72 - 72 = 180 - 72 ( simplify both sides )

9y = 108 ( divide both sides by 9 )

(9)/(9) y = (108)/(9) , that is

y = 12
