Answer:

Step-by-step explanation:

Operations of functions:

h(x) = f(z) + g(z)

h(x) = (2z³ - 3z) + (-3z² + 1)

Simplify or expand:

(2z³ - 3z) + (-3z² + 1)

Determine the sign

2z³ - 3z - 3z² + 1

Rewrite the expression

2z³ - 3z² - 3z + 1

Calculate:

Substitute z = 3 into

2z³ - 3z² - 3z + 1

Substitute

2 × 3³ - 3 × 3² - 3 × 3 + 1

Calculate

Answer:

The probability that a student taking only math will get picked is approximately 29%

Step-by-step explanation: This is because out of the total number of students taking math (95), 52 of such students are also taking science. In order to get the number of students only taking math you have to do 95-52=43 and to put that against the amount of total students the ratio would be 43:147 or 42/147 and if you plug 42/147 into a calculator you will recieve a long decimal that you can then round to 29%.

The sum of three consecutive numbers is 72. What is the largest of these numbers?

kicyunya [14]

3 consecutive numbers....x, x + 1 and x + 2

x + x + 1 + x + 2 = 72
3x + 3 = 72
3x = 72 - 3
3x = 69
x = 69/3
x = 23

x + 1 = 23 + 1 = 24
x + 2 = 23 + 2 = 25

so ur numbers are 23,24,25 with 25 being the largest
