Rosa Loves To Run. She Set A Goal To Run Greater Than 490 Miles This Year. To Date, She Has Run 145 Miles.

Answers

Answer 1

Answer:

Step-by-step explanation:

145+15x>490. subtract 145 from both sides

15x>345, divide both sides by 15

x>23

So she will need to run for more than 23 weeks to reach her goal.

Answer:

(a)Yellow=10

Green=38

Relative Frequency of Blue =0.32

Relative Frequency of Red =0.2

Relative Frequency of Green =0.38

(b)50 Red balls

Step-by-step explanation:

In 100 trials, the following were recorded.

Frequency of Blue Balls = 32

Frequency of Red Balls = 20

Relative Frequency of Yellow Balls =0.1

Now, Relative Frequency =Number of Outcome of an Event ÷ Total Number of Trials in the Experiment

Total Number of Trials =100

Therefore:

Therefore, Number of Outcomes of Green balls=100-(32+20+10)

=100-62

Number of Outcomes of Green balls=38

(b)If the Number of Trials is Increased to 250

Expected Outcome of Red Balls =Relative Frequency of Red Balls X 250

She should expect 50 red balls.

4. Which of these points does not lie on the graph of y=-2x+7?
(A) (-1,9
(B) (4,-1)
(C) (-3,1)
(D) (-2.11)

Answers

c.) -3, 1. is the answer because when you look at the graph it’s the only one that doesn’t touch the line through the graph.

The point (-3,1) is not passing through the graph y = -2x + 7 so option (C) will be correct.

How to plot a graph?

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given that a line  y=-2x+7

Now in order to satisfy any point of this function then the value or

coordinate should satisfy the function or line.

So by checking option (A) 9 = -2(-1) + 7 = 9 so its satisfy.

So all options except (C) are satisfying.

Option (C) ⇒

-2(-3) + 7  ≠ 1

Hence "The point (-3,1) is not passing through the graph y = -2x + 7".

In ΔMNO, n = 85 inches, o = 10 inches and ∠M=56°. Find the length of m, to the nearest inch.

Answers

Answer:

80

Step-by-step explanation:

Delta math math

The length of m in triangle MNO is approximately 80 inches.

What is a Triangle?

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.

In ΔMNO, n = 85 inches, o = 10 inches, and ∠M=56°.

In this case, we are given the lengths of sides n and o and the measure of angle M. We can use the law of cosines to solve for the length of side m:

⇒ m² = n² + o² - 2 × n × o × cos(∠M)

We are given that n = 85 inches, o = 10 inches, and ∠M = 56°. We can use these values to solve for m:

⇒ m² = 85² + 10² - 2 × 85 × 10 × cos (56°)

We can use a calculator or look up the value of cos 56° to find that it is approximately 0.6. Plugging this value into the formula above gives us:

⇒ m = 79.8397 ≈ 80 inches

Therefore, the length of m in triangle MNO is approximately 80 inches to the nearest inch.

If 420 = 120%, what would 100% equal?

Answers

Answer:

350

Step-by-step explanation:

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100

120% = 120/100 = 120 ÷ 100 = 1.2

100% = 100/100 = 100 ÷ 100 = 1

Percentage of 120% of what number = 420?

120% × ? = 420

? =

420 ÷ 120% =

420 ÷ (120 ÷ 100) =

(100 × 420) ÷ 120 =

42,000 ÷ 120 =

350

ProofHow do we check the result?

If 120% × 350 = 420 =>

Divide 420 by 350...

... And see if we get as a result: 120%

Note:

Multiply a number by the fraction 100/100,

... and its value doesn't change.

100/100 = 100 ÷ 100 = 1

n/100 = n%, any number.
