The probability that Ismael makes a basket is 7/10. If he shoots 100 baskets, how many can he expect to make?
sdas [7]

Answer:

70 baskets

Drag the tiles to the correct boxes to complete the pairs. Solve the inequalities for x, and match each solution to its number l
svetlana [45]

in the figure, the first number line goes with x \leq5

the second number line goes with x \geq 5

the third number line goes with x > 5

the fourth number line goes with x < 5

Two less than 3/2 of a number x is  no more than 5/2 is shown as:

3/2 x- 2 \leq 5 1/2

3/2 x \leq 11/2 + 2

3/2 x \leq 15/2

3x \leq 15

x \leq 5

The sum of two times a number (x) and -2 is at least 8 is shown as :

2x+(-2) \geq 8

2x - 2 \geq 8

2x \geq 8+2

2x \geq 10

x \geq 5

Seven subtracted from 4 times a number (x) is more than 13 is shown as

4x -7 > 13

4x > 13+7

4x > 20

x > 20 ÷ 4

x > 5

Four added to 3 times a number (x) is less than 19 is shown as

3x + 4 < 19

3x < 19-4

3x < 15

x < 15 ÷ 3

x< 5

Jaxon is traveling from Portland, Oregon to Denver, CO. If he were traveling by car, he would drive 1000 miles east and 575 mile
nordsb [41]

Answer:

1153.5 miles (first answer choice)

Step-by-step explanation:

'1000 miles east' is the change in x ('the run'), and '575 miles south' is the change in x (the 'rise').  Since these two vectors form a right angle, we can immediately apply the Pythagorean Theorem without worrying about signs:

d = √(1000² + 575²) = 1153.5 miles (first answer choice)
