Answer:

Step-by-step explanation:

Given the expression

g(x) = x⁴ - 4x² + 7x - 8

we are expected to substitute x=2 into the expression and return the result

g(x) = (2)⁴ - 4(2)² + 7(2) - 8

g(x) = 16 - 4x4 + 14 - 8

g(x) = 16 - 16 + 14 - 8

g(x) =14 - 8

g(x) =6

From the substitution the roller coaster is  travelling at speed of 6mph

Answer: [tex]3.5[/tex] × [tex]10^{4}[/tex]

Step-by-step explanation:

Write an expression to represent the problem.

(8.2 × 10²) × 43

= (8.2 × 10²) x (4.3 x [tex]10^{1}[/tex])

Now, multiply.

(8.2 × 10²) x (4.3 x [tex]10^{1}[/tex])

= (8.2 x 4.3) x ([tex]10^{2}[/tex] x [tex]10^{1}[/tex])

= 35.26 x [tex](10)^{2+1}[/tex]

= 35.26 x 10³

= 3.526 x [tex]10^{4}[/tex]

ok so you are looking for the unit rate.

Answers:

a) First statement. Same as 1/2 x 6/11.

b) Second statement. Smaller than 6/11.

c) First statement. Same as 6/11 divided by 2.

================================================

Explanation:

Part (a)

The "of" means "multiply". So we simply replace "of" with the multiplication symbol and that's all we need to do.

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

Part (b)

Taking half of something will make it smaller. For example, if you have 100 cookies and you took half of them, then you'll be taking 50 cookies. The value 50 is smaller than 100.

The same idea applies to 1/2 x 6/11.

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

Part (c)

Multiplying by 1/2 is the same as dividing by 2.

So [tex]\frac{6}{11} \times \frac{1}{2} = \frac{6}{11} \div 2[/tex]

Note that [tex]\frac{1}{2} \times \frac{6}{11}[/tex] and [tex]\frac{6}{11}\times \frac{1}{2}[/tex] are the same thing because we can multiply two numbers in any order we want.

Answer:

a) First statement. Same as 1/2 x 6/11.

b) Second statement. Smaller than 6/11.

c) First statement. Same as 6/11 divided by 2.

Answer:

Generally the probability distribution of the number of white balls (X) is

       X             0                         1                   2

       P(X)        0.35714           0.5357         0.10714

Step-by-step explanation:

From the question we are told that

 The number of white balls is  [tex]N_w = 5[/tex]

  The number of black balls is  [tex]N_b = 3[/tex]

Generally the total number of balls the urn contains is

     [tex]N_t = N_w + N_b = 5 + 3 = 8 \ balls[/tex]

Generally the probability that of the two balls drawn that the balls are  2 white balls and  0 black balls is

     [tex]P( 2_w \ , 0_b) = \frac{ ^{N_w} C _2 * ^{N_b} C _0 }{^{N_t} C_2}[/tex]

Here C stands for combination hence we would be making use of the combination feature in our calculator

=> [tex]P( 2_w \ , 0_b) = \frac{ ^5 C _2 * ^3 C _0 }{^{8} C_2}[/tex]

=> [tex]P( 2_w \ , 0_b) = 0.10714[/tex]

Generally the probability that of the two balls drawn that the balls are  1 white balls and  1 black balls is

     [tex]P( 1_w \ , 1_b) = \frac{ ^{N_w} C _1 * ^{N_b} C _1 }{^{N_t} C_2}[/tex]

=> [tex]P( 1_w \ , 1_b) = \frac{ ^5 C _1 * ^3 C _1 }{^{8} C_2}[/tex]

=> [tex]P( 1_w \ , 1_b) = 0.5357[/tex]

Generally the probability that of the two balls drawn that the balls are  0 white balls and  2 black balls is

     [tex]P( 0_w \ , 2_b) = \frac{ ^{N_w} C _0 * ^{N_b} C _2}{^{N_t} C_2}[/tex]

=> [tex]P( 0_w \ , 2_b) = \frac{ ^5 C _0 * ^3 C _2 }{^{8} C_2}[/tex]

=> [tex]P( 0_w \ , 2_b) = 0.35714[/tex]

Generally the probability distribution of the number of white balls (X) is

       X             0                         1                   2

       P(X)        0.35714           0.5357         0.10714

Answer:

[tex]\boxed {k = 2}[/tex]

Step-by-step explanation:

Solve for the value of [tex]k[/tex]:

[tex]-5k = -10[/tex]

-Divide both sides by [tex]-5[/tex]:

[tex]\frac{-5k}{-5} = \frac{-10}{-5}[/tex]

[tex]\boxed {k = 2}[/tex]

Therefore, the value of [tex]k[/tex] is [tex]2[/tex].

Step-by-step explanation:

The amount of pounds of pumpkin made in 30minutes is 96 pounds

Fractions are written as a ratio of two integers.

If Michael makes 16/5 pounds of pumpkin pie filling per minute, then;

16/5 pounds of pumpkin = 1 minutes

In order to determine the amount made in half an hour (30 mins)

x = 30mins

Take the ratios

16/5x = 1/30
5x = 480

x = 480/5

x = 96

Hence the amount of pounds of pumpkin made in 30minutes is 96 pounds

Answer:

h = 4 hours

Step-by-step explanation:

Charges per hour = $35

Registration fee = $15

Janice's parents paid $155 in the month of August.

Let

h = number of hours

equation to determine how many hours of batting lessons Janice had in the month of August.

15 + 35h = 155

B. 15 + 35h = 155

35h = 155 - 15

35h = 140

Divide both sides by 35

h = 140 / 35

= 4

h = 4 hours

Answer:

3 students

Step-by-step explanation:

Mrs. Grape has 90 students. On her last test, 3/10 of these students earned an A.

Hence, the number of students that had an A = 3/10 × 90

= 3 × 9 = 27 students

Of those students, 1/9 got a perfect score.

This means of the 27 students, 1/9 had a perfect score.

This means:

1/9 of 27 students = 1/9 × 27

= 3 students

How many students got a perfect score?

Hence, 3 students got a perfect score.

Answer: SUGAR/FLOUR

Step-by-step explanation: proof / Edge 2022

By putting every value of table x,   y = (96 / x) this gives the output of table y so that this is the correct answer.

By definition, it is known that speed equals the ratio of distance and time.

Speed = Distance / Time

Therefore, according to the definition, the last two options are the possible

 Let's evaluate the First option:

y = x/96

= 12/96

= 1/8

The table is not fulfilled

Let's evaluate the Second option: (12,8)

y= 2x/3

y= 2*12/3

y = 8

NOW,

(16, 6)

y= 2x/3

2*16/3

the answer will be on a fraction

The table is not fulfilled

Let's evaluate the third option:

y = (3/2) * (1 / x)

x = 12

y = (3/2) * (1/12) = 3/24 = 1/8

The table is not fulfilled

Let's evaluate the fourth option:

y = (96 / x)

x = 12

y = (96/12) = 8

Yes, the table is met.

Option 4 )  y = (96 / x)

By putting every value of table x,   y = (96 / x) this gives the output of table y so that this is the correct answer.
