Answer;

D

Step-by-step explanation:

Train A by a factor of 1.1

Train A:  

173

5

= 34.6

Train B: Rate is the slope of the equation, 31.35

Thus,

34.6

31.35

= 1.1036

Shaun read 60 pages in 3/4 h. What is the unit rate that represents the number of pages Shaun can read in 1 h?
Alexus [3.1K]

Answer:

60=3/4

x=4/4

4/4÷1/4

4/4*4/1

4/1*1/1

4/1

4

3/4=12 because if 1/4 is 4 then 3/4 is 12

60=12

60÷12=5

5*4/20

60+20=80

Shaun will read 80 pages in 1 hour

In a football tournament, the Bees scored 9 less than three times as many points as the Hornets. The Wasps scored 28 more points
Alinara [238K]

Answer:

  • <u>The Bees scored 90 points.</u>

Explanation:

First, let's prove that the equation is correct.

To create the equation, you translate the verbal statements into algebraic expressions.

Since, it is said that x respresents the number of points scored by the Hornets, that is your variable and all the verbal statements will be translated using x:

a) NUmber of points scored by the Hornets: x

b) The Bees scored 9 less than three times as many points as the Hornets ⇒v3x - 9

c) The Wasps scored 28 more points than the Hornets ⇒ x + 8

d) Together the three teams scored 184 points ⇒

 

  • x + (3x - 9) + (x + 28) = 184

Which indeed is the given equation: (3x – 9) + x + (x + 28) = 184

Now, complete the steps to show it, in the same order given:

<u>1. Combine like terms. </u>

  • Remove the parenthesis: x + 3x - 9 + x + 28 = 184

  • Combine the terms on x on the left: x + 3x + x = 5x

  • Combine the constants on the left: - 9 + 28 = 19

  • Write the result: 5x + 19 = 184

<u>2. Use the subtraction property of equality. </u>

  • Subtract 19 from both sides: 5x + 19 - 19 = 184 - 19

  • Due the operations: 5x = 165

<u>3. Use the division property of equality. 4. </u>

  • Divide both sides by 5: (5x / 5) = 165 / 5

  • Due the operations: x = 33

<u>4. Use the variable to answer the question. How many points did the Bees score?</u>

  • The expression for the points scored by the Bees is 3x - 9, so substitute x in that expression: 3 (33) - 9 = 99 - 9 = 90.

  • Answer: the Bees scored 90 points.

Nevaeh has $560 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. She buys
AnnyKZ [126]

Answer:

The number of outfits she purchase with the left money = 3

Step-by-step explanation:

The exact question is as follows :

Given - Nevaeh has $560 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. She buys a new bicycle for $383.32. She buys 4 bicycle reflectors for $9.09 each and a pair of bike gloves for $21.07. She plans to spend some or all of the money she has left to buy new biking outfits for $39.75 each.

To find - Write and solve an inequality which can be used to determine  x  where x, the number of outfits Nevaeh can purchase while staying within her budget.

Proof -

Given that,

Total money Nevaeh have = $ 560

She spent money on bicycle = $ 383.32

She spend money on 1 reflector = $ 9.09

As she buy 4 bicycle reflector, So

Total money spent on bicycle reflector = $ 4×9.09 = $ 36.36

She spend money on a pair of bike gloves = $ 21.07

So,

Total money she spend on the items = $ 383.32 + 36.36 + 21.07

                                                              = $ 440.75

⇒Total money she spend on the items = $ 440.75

So,

Total money Left = $ 560 - $ 440.75 = $ 119.25

Now,

She plans to spend some or all of the money she has left to buy new biking outfits for $ 39.75 each.

Let us assume ,

The number of outfits she purchase with the left money = x

AS,

each outfit cost = $ 39.75

So, x outfits cost = $ 39.75 x

Now,

$ 39.75 x = $ 119.25     (because total money left = $ 119.25)

⇒ x = \frac{119.25}{39.75} = 3

∴ we get

The number of outfits she purchase with the left money = x = 3

Suppose two different methods are available for eye surgery. The probability that the eye has not recovered in a month is 0.002
umka21 [38]

Answer:

0.4007

Step-by-step explanation:

Let's define the following events:

A: method A is used

B: method B is used

NR: the eye has not recovered in a month

R: the eye is recovered in a month

The probability that the eye has not recovered in a month is 0.002 if method A is used, i.e., P(NR|A) = 0.002, so P(R|A) = 0.998.

When method B is used, the probability that the eye has not recovered in a month is 0.005, i.e., P(NR|B) = 0.005, so P(R|B) = 0.995.

40% of eye surgeries are done with method A, i.e., P(A) = 0.4

60% of eye surgeries are done with method B, i.e., P(B) = 0.6

If an eye is recovered in a month after surgery is done in the hospital, what is the probability that method A was performed? We are looking for P(A|R), then, by Bayes' Formula

P(A|R) = P(R|A)P(A)/(P(R|A)P(A) + P(R|B)P(B)) = 0.998*0.4/(0.998*0.4 + 0.995*0.6) = 0.4007
