Valeria is training for a marathon. She jogs the same 15 mile route twice in one week. On Monday, she jogged the route in 1.75 hours. Thursday, she tried to improve her speed. She jogged the same route in 1.63 hours. Her smart watch said her rate on Monday was 8.57 miles per hour. She forgot to set the smart watch to calculate her rate on Thursday. Use the information you have to calculate how fast she was running on Thursday.

Answers

Answer:

9.20 miles per hour

Step-by-step explanation:

Given data

distance of the route = 15miles

time taken on Monday= 1.75hours

speed= distance./time

speed= 15/1.75

speed= 8.57 miles per hour

her smart watch is correct

time taken on Thursday= 1.63hours

speed= distance./time

speed= 15/1.63

speed= 9.20 miles per hour

she was jogging at 9.20 miles per hour

i had 6 cupcakes two days ago, and 9 yesterday. help me continue this pattern. thank you.

Answers

Answer:

its adding 3

Step-by-step explanation:

So if you had 6 cupcake two days ago, than yesterday there was 9, so tomorrow you should have 12 cupcake and so on

The requried pattern of cupcakes is given by adding 3 cupcakes each day and the pattern comes out as 6, 9, 12, 15, 18, 21, and so on for the subsequent day.

What is a sequence?

The sequence is a pattern of placing the values in a specified manner.

Here,
Assuming that the pattern is to add 3 cupcakes each day, the continuation of the pattern would be:

Two days ago: 6 cupcakes

Yesterday: 9 cupcakes

Today: 12 cupcakes

Tomorrow: 15 cupcakes

Day after tomorrow: 18 cupcakes

In five days: 21 cupcakes

And so on, the pattern would continue adding 3 cupcakes for each subsequent day.

No more than will be invested in​ medium- and​ high-risk stocks. The expected yields are ​% for​ low-risk stocks, ​% for​ medium-risk stocks, and ​% for​ high-risk stocks. How much money should Mr. Jones invest in each type of stock to maximize his total expected​ yield?

Answers

Answer:

Since the numbers are missing, I looked for a similar question:

Mr. Jones has $9000 to invest in three types of stocks: low-risk, medium-risk and high-risk. He invests according to the following rules: the amount invested in low-risk stocks will be at most $1000 more than the amount invested in medium-risk stocks. At least $7000 will be invested in a combination of low- and medium-risk stocks. No more than $7000 will be invested in a combination of medium- and high-risk stocks. The expected annual returns are 6% for low-risk stocks, 7% for medium-risk stocks, and 8% for high-risk stocks. How much should he invest in each type of stock to maximize his total expected yield?

let:

L = low risk stocks

M = medium risk stocks

H = high risk stocks  

maximize 0.06L + 0.07M + 0.08H

L + M + H ≤ 9000

L ≥ M + 1000

L + M ≥ 7000

M + H ≤ 7000

using solver, the optimal solution = 4,000L + 3,000M + 2,000H , which yields a maximum profit = $610

Mr. Jones should invest $4,000 in low risk stocks, $3,000 in medium risk stocks and $2,000 in high risk stocks.

2b.) What transformation of f(x) does y correspond to?

a.) a verticle translation 4 units down
b.) a verticle translation 4 units up
c.) a horizontal translation 4 units to the left
d.) a horizontal translation 4 units to the right

Answers

Answer:

The transformation is " a horizontal translation 4 units to the right " ⇒ (d)

Step-by-step explanation:

Let us revise the translation of a function

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)  If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)  If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k  If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k

Let us look at the graph and choose some points on the f(x) and find their images on y

∵ Point  (1, 2) lies on f(x)

∵ Point (5, 2) lies on y

∵ Point  (3, 8) lies on f(x)

∵ Point (7, 8) lies on y

→ There is no change in the y-coordinates of the points, the change

  only in the x-coordinates

∴ The translation is horizontally

∵  5 - 1 = 4 units ⇒ positive value means to right

∴ f(x) is translated 4 units to the right

The answer is " a horizontal translation 4 units to the right " (d)

Find the slopes of the linear functions.
y = -2x + 7
The slope of the line given by the linear equation is
ty
The slope of the line shown in the graph is

4

Answers

Answer:

The slope of the line given by the linear equation is -2

The slope of the line shown in the graph is -1

Step-by-step explanation:

The line equation, y = -2x + 7 is written in the slope-intercept form, which is represented by the formula, y = mx + b.

m is the slope, while b is the y-intercept.

Therefore, the slope of the line of the linear equation, y = -2x + 7 is -2.

Find the slope of the line shown in the graph using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex].

Use the coordinates of any two points on the line. Let's use (0, 5) and (5, 0)

Let,

[tex] (0, 5) = (x_1, y_1) [/tex]

[tex] (5, 0) = (x_2, y_2) [/tex]

[tex] m = \frac{0 - 5}{5 - 0} = \frac{-5}{5} = -1 [/tex]

Therefore:

The slope of the line given by the linear equation is -2

The slope of the line shown in the graph is -1

Marlina received her salary on Friday. She spent one-half of her salary on rent and then spent $338 on her electric and water bill. Next, she spent one-half of what was left on her phone bill. After spending $56.00 on gas for her car, Marlina had $102.00 left. How much did Marlin spend on rent?

Answers

Answer:

Marlina spent $654 on rent.

Step-by-step explanation:

Let the amount of money Marlina's received for her salary be x.

We know that she spent one-half of her salary on rent and then $338 on her electric and water bill. Therefore, the amount of money she has left can be so far can be represented by:

[tex]\displaystyle x-\frac{1}{2}x-338[/tex]

Next, she spent one-half of what was left on her phone bill. So, we can subtract one-half of the above expression to what we have so far.

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}\left(x-\frac{1}{2}x-338\right)[/tex]

Finally, she spent $56 for gas. Thus, we will subtract 56:

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}\left(x-\frac{1}{2}x-338\right)-56[/tex]

And we know that after all of the expenses, she will have $102 left. Therefore:

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}\left(x-\frac{1}{2}x-338\right)-56=102[/tex]

We want to know how much Marlina spent on rent. So, we can find her salary, since we know the rent is one-half of the salary. To find the salary, we will solve for x.

Distribute:

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}x+\frac{1}{4}x+169-56=102[/tex]

Rearrange:

[tex]\displaystyle \left(x-\frac{1}{2}x-\frac{1}{2}x+\frac{1}{4}x\right)+(-338+169-56)=102[/tex]

Combine like terms:

[tex]\displaystyle \frac{1}{4}x-225=102[/tex]

Add 225 to both sides:

[tex]\displaystyle \frac{1}{4}x=327[/tex]

Multiply both sides by 4:

[tex]x=\$ 1308[/tex]

Therefore, Marlina received a total of $1308 for her salary.

We know that she spent half of her salary on rent. Therefore, the amount she spent on rent is:

[tex]\displaystyle r=\frac{1}{2}(1308)=\$ 654[/tex]

Marlina spent a total of $654 on rent.

9514 1404 393

Answer:

  $654

Step-by-step explanation:

Let r represent the amount of Marlina's rent. Since that is half her salary, the amount remaining after paying rent is also equal to r. The disposition of that remaining amount is ...

  $338 on electric and water (E&W)

  (1/2)(r -338) on phone . . . this is half of what is left after paying E&W

  $56 on gas

  $102 unaccounted

__

The total of these amounts is equal to r, so we have ...

  r = 338 + 1/2(r -338) +56 +102

  1/2r = 338 -169 +56 +102 = 327 . . . . . eliminate parentheses, subtract 1/2r

  r = 2(327) = 654 . . . . . multiply by 2 to get r by itself

Marlina spends $654 on rent.

A superstar major league baseball player just signed a new deal that pays him a record amount of money. The star has driven in an average of 110 runs over the course of his career, with a standard deviation of 31 runs. An average player at his position drives in 80 runs. What is the probability the superstar bats in fewer runs than an average player next year

Answers

Answer:

0.1667

Step-by-step explanation:

Given that:

Average / mean runs (m) = 110 runs

Standard deviation (σ) = 31 runs

Number of runs driven in by an average player in his position = 80

The probability the superstar bats in fewer runs than an average player next year will be the :

P(x < 80)

Zscore = (x - mean) / σ

Zscore = (80 - 110) / 31

Zscore = - 30 / 31

Zscore = - 0.9677419

P(Z < 0.9677419) = 0.1666 ( from z probability calculator)

= 0.1667
