Lebron James's Free Throw % is 75%

What is the probability that he makes 6 Free Throws in a row?

Answer as a decimal rounded to 2 places.

Answers

Answer: 0.18

Step-by-step explanation:

From the question, we are informed that Lebron James's Free Throw % is 75%. The probability that he makes 6 Free Throws in a row would be gotten by multiplying 75% six times. This will be:

= 75% × 75% × 75% × 75% × 75% × 75%

= 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4

= 729/4096

= 0.18

Truck drivers report the mileage or the number of miles (M) traveled per gallon of gas (G) for each trip. Which driver went the farthest on one gallon of gas.

Answers

Answer:

B. Andy

Step-by-step explanation:

Kelly's mileage

This is proportional relationship, so one pair of coordinates is enough for our calculation, point (20, 50):

m = 50/20 = 2.5 gAndy's mileage

Use one pair of points from the table to calculate (15, 78.75):

m = 78.75/15 = 5.25 gRick's mileage is given:m = 4.8 g

Comparing, we see Andy's mileage is largest.

Andy will travel farther than the other drivers.

To find the square root of a number, you must divide the number by 2.

True

False

Answers

Answer:

False

Step-by-step explanation:

When you are squaring a number, you multiply the number by itself (7*7 or 12*12), so if you were to reverse that and find the square root of the number (let's say 49), you'd have to do some guess and check and figure out which number, when multiplied with itself, would equal that number (7*7 = 49).

The square roots of a number are the number by which multiply with the same number we will get the number thus the given statement is completely False.

What is a number system?

The number system is a way to represent or express numbers.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number b.

Consider the number 9.

The square root of it is given as,

√(9) = 3

Now, if we multiply 3 by 3 then we get 9 as,

3 x 3 = 9

If we divide 3 by 2 then 3/2 = 1.25 is not 9.

Hence "The square roots of a number are the number by which multiply with the same number we will get the number thus the given statement is completely False".

The area of a rectangular wall of a barn is 153 square feet. Its length is 8 feet longer than the width. Find the length and width of the wall of the barn.

Answers

Answer and Step-by-step explanation:

Area (A) = 153

Length (l) = 8 + w

Width (w) = w

A = lw

153 = (8 + w)(w)

153 = [tex]w^{2} + 8w[/tex]

0 =  [tex]w^{2} + 8w[/tex] - 153

 [tex]w^{2} -9w + 17w - 153[/tex]

(w - 9)(w + 17)

w = 9

w = -17

We can't have a negative length, so we only use 9.

w equals 9.

That means l equals 17     (9 + 8 = 17).

Length = 17

Width = 9

Answers

Answer:

x<2

Step-by-step explanation:

The given inequality is :

3x-2<4

We need to find the solution of the inequality.

3x<6

Dividing both sides by 3.

x<2

Hence, the solution of the given inequality is x<2.
