let f(x)=-2x-7 and g(x)=-4x+3 find (f°g)(-5)

Answers

Answer 1

Answer:

-53

Step-by-step explanation:

f°g = f(g(x))     Remember this because this notation is less confusing for you.

Step 1. Plug g(x) in all values of x in the function f(x).

f(g(x)) = -2(-4x+3) -7

Step 2. Distribute the -2

-2(-4x+3) = 8x -6

f(g(x)) = 8x-6-7

Step 3. Simplify by subtracting -6 - 7

f(g(x)) = 8x-13

Step 4. Plug in -5 for x

8(-5) - 13 = -40 - 13 = -53

Sophie has 7 cookies she wants to share equally with ten friends at her party. Part A If she separates all of the cookies and gives each friend an equal amount, how much cookie will each friend receive? Part B If Sophie wanted to give each friend 1 1/2 cookies, how many more cookies would she need?

Answers

Answer:

Each friend gets 0.7 cookie

8 cookies

Step-by-step explanation:

A.

Number of cookies = 7

Number of friends = 10

how much cookie will each friend receive?

Number of cookie each friend get = number of cookies / number of friends

= 7/10

= 0.7 cookie

Each friend gets 0.7 cookie

B.

If each friend 1 1/2 cookies

how many more cookies would she need?

Total number of cookies needed = 1 1/2 × 10

= 3/2 × 10

= 30/2

= 15 cookies

She already has 7 cookies

Number of cookies needed more = 15 cookies - 7 cookies

= 8 cookies

ratios that are equivalent to 9:6.

Answers

Answer:

3:2

Step-by-step explanation:

Answer:

3:2 , 18:12 , 27:18

Step-by-step explanation:

There are endless ratios that are equal to 9:6.

Such as 3:2 , 18:12 , and 27:18.

To find equivalent ratios, simply divide or multiply the two numbers in the ratio by the same number.

For example, the ratio is 9:6.

9/3 = 3

And, 6/3 =2

So therefore an equivalent ratio is 3:2.

Radius of cone (r) = 24/2 = 12 units

Height of cone (h) = 28 units

[tex]V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ = \frac{1}{ 3} \times 3.14 \times {(12)}^{2} \times 28 \\ \\ = \frac{1}{3} \times 3.14 \times 144 \times 28 \\ \\ = 3.14 \times 1,344 \\ \\ = 4,220.16\: {units}^{3} [/tex]

Answer:

2/5 < 7/10

The least common denominator is 10 so if you do 5*2 = 10 and 2*2 = 4 then compare it to 7/10, it would be less than because 4/10 is not greater than 7/10.

A basketball team won 72.5% of their games. Find the probability they win 16 if their next 30 games.

Answers

Answer:

0.00987

Step-by-step explanation:

Using binomial probability formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

p = 0.725 ; number of trial, n = 30

Number of winning, x = 16

1 - p = 1 - 0.725 = 0.275

P(x = 16) = 30C16 * 0.725^16 * 0.275^14

P(x = 16) = 119759850 * 0.725^16 * 0.275^14

P(x = 16) = 0.00987

Hence, the probability of winning 16 of their next 30 games is 0.00987

AB and CD are straight line segments.
∠ AOE = 50° and ∠ DOB = 95°.
Find the values of the following angles giving a reason for each answer in the comment box.
The diagram is not drawn accurately.
i) obtuse ∠ AOC
ii) acute ∠ BOC
iii) acute ∠ DOE

Answers

Answer:

i) Angle AOC is 95° Reason:- Angle AOC is equal to Angle DOB since they are Vertically Opposite Angles.

ii) Angle BOC is 85° Reason:- Angle AOC + Angle BOC - 180° (they lie in a straight line so they are a linear pair. Sum of the angles will be 180°) Angle AOC is 95°, So:- 95° + Angle BOC = 180° Angle BOC= 180° - 95° Angle BOC = 85° iii) Angle DOE is 17° Reason:- Angle AOE+ Angle DOE+ Angle DOB = 180° (they lie in a straight line so they're a linear pair. Sum of the angles will be 180°) So, 68° + Angle DOE+ 95° = 180° 163° + Angle DOE = 180° Angle DOE= 180° - 163° Angle DOE is 17°

Which statement is correct regarding independent events?

OTwo events are independent if they have outcomes in common and can occur at the same time.
OTwo events are independent if the outcome of the first event does not affect the outcome of the second event.
O Two events are independent if the outcome of the first event affects the outcome of the second event.

Answers

Answer:

Two events are independent if the outcome of the first event does not affect the outcome of the second event.

Step-by-step explanation:

two events are independent if the occurrence or outcome of the  first event does not affect the outcome or occurrence of the second event.

for example, if you flip a coin the first time and the outcome is a head and you flip a second time and you get a tail. the occurrence of these two event are independent of each other. Thus they are independent events

two outcomes are dependent if the outcome one event is determined by the outcome of the first event.
