Answer:

27

Step-by-step explanation:

Given

4² ÷ 2 × 3 + \sqrt{25-16} ← evaluate exponent

= 16 ÷ 2 × 3 + \sqrt{9}

When division and multiplication appear in the calculation evaluate from left to right.

= 8 × 3 + 3

= 24 + 3

= 27

Answer:

1. Exponent

2. Multiplication

3. Subtraction

4. Square root

5. Addition

6. Division?

<em>Note: I am not very sure about my answer because of two things. 1. The proper order for operating is PEDMAS (Parentheses, Exponent, Multiplication, division, addition, and subtraction). There is no Square root in that operation so I will consider it in the middle. 2. There is no division operation in this problem.</em>

The driving distance for the top 100 golfers on the PGA tour is between 284.7 and 310.6 yards (according to GolfWeek). Assume th
Usimov [2.4K]

Answer:

a) f(x) = \frac{1}{25.9}

b) 0.2046 = 20.46% probability the driving distance for one of these golfers is less than 290 yards

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

P(X < x) = \frac{x - a}{b - a}

The probability of finding a value between c and d is:

P(c \leq X \leq d) = \frac{d - c}{b - a}

The probability of finding a value above x is:

P(X > x) = \frac{b - x}{b - a}

The probability density function of the uniform distribution is:

f(x) = \frac{1}{b-a}

The driving distance for the top 100 golfers on the PGA tour is between 284.7 and 310.6 yards.

This means that a = 284.7, b = 310.6.

a. Give a mathematical expression for the probability density function of driving distance.

f(x) = \frac{1}{b-a} = \frac{1}{310.6-284.7} = \frac{1}{25.9}

b. What is the probability the driving distance for one of these golfers is less than 290 yards?

P(X < 290) = \frac{290 - 284.7}{310.6-284.7} = 0.2046

0.2046 = 20.46% probability the driving distance for one of these golfers is less than 290 yards

What is the X<br> 3x +15 and 2x + 20
Georgia [21]

Answer:

<h2><u><em>x = 5</em></u></h2>

Step-by-step explanation:

What is the X

3x +15 and 2x + 20

assuming that the question is an equation

3x + 15 = 2x + 20

3x - 2x = 20 - 15

x = 5

-----------------

check

3 * 5 + 15 = 2 * 5 + 20

30 = 30

the answer is good
