Nathan is a recreational cyclist. He can travel 10 miles in one hour on his bicycle. Which graph represents the number of miles Nathan can travel in x hours?
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]1\ hr = 10\ miles[/tex]
Required
The graph that shows the number of miles in x hours
We have:
[tex]1\ hr = 10\ miles[/tex]
Multiply both sides by x
[tex]x * 1hr = 10miles * x[/tex]
[tex]xhr=10x\ miles[/tex]
So, the function is:
[tex]f(x) =10x[/tex]
4) If the sum of two numbers is 64, and the larger number is 3 less than 3 times the
smaller number. Find the smaller number.
Answer:
x = 67/4
Step-by-step explanation:
Let x = smaller number and y = bigger number
Then x +y = 64 and y = 3x-3
Plugging y into x+y = 64
x + 3x -3 = 64
4x = 67
x = 67/4

A recent study1 examines chocolate’s effects on blood vessel function in healthy people. In the randomized, double-blind, placebo-controlled study, 11 people received 46 grams (1.6 ounces) of dark chocolate (which is naturally flavonoid-rich) every day for two weeks, while a control group of 10 people received a placebo consisting of dark chocolate with low flavonoid content. Participants had their vascular health measured (by means of flow-mediated dilation) before and after the two-week study. The increase over the two-week period was measured, with larger numbers indicating greater vascular health. For the group getting the good dark chocolate, the mean increase was 1.3 with a standard deviation of 2.32, while the control group had a mean change of -0.96 with a standard deviation of 1.58.
Find a 90% confidence interval for the difference in means between the two groups MC-MN , where MC represents the mean increase in flow-mediated dilation for people eating dark chocolate every day and MN represents the mean increase in flow-mediated dilation for people eating a dark chocolate substitute each day. You may assume that neither sample shows significant departures from normality.
Round your answers to two decimal places.
Answer:
CI = (0.68, 3.84)
Step-by-step explanation:
We want to find the confidence interval for the difference in means between the two groups MC and MN.
where;
- MC represents the mean increase in flow-mediated dilation for people eating dark chocolate every day.
- MN represents the mean increase in flow-mediated dilation for people eating a dark chocolate substitute each day.
We are given;
Sample mean of C; x'c = 1.3
Sample mean of N; x'n = -0.96
Standard deviation of C; S_c = 2.32
Standard deviation of N; S_n = 1.58
Sample size of C; n_c = 11
Sample size of N; n_n = 10
Formula for the confidence interval for the difference in means is;
CI = (x'c - x'n) ± t√[(S_c²/n_c) + (S_n²/n_n)]
Where t is critical value at confidence level. From table attached, t at CL of 90% with DF = 10 - 1 = 9 is; t = 1.833
Thus;
CI = (1.3 - (-0.96)) ± 1.833√[(2.32²/11) + (1.58²/10)]
CI = [(1.3 + 0.96)) - 1.833√[(2.32²/11) + (1.58²/10)], [(1.3 + 0.96)) + 1.833√[(2.32²/11) + (1.58²/10)]
CI = (2.26 - 1.58), (2.26 + 1.58)
CI = (0.68, 3.84)
There are 4 blueberry, 6 raisins, and 2 plain bagels in a bag. Mike randomly selects two bagels without replacing the first bagel. Find the probability that he selects a raisin bagel and then a plain bagel
Answer: 1/9
Step-by-step explanation: add all the numbers up, so 4+6+2=12, which is the denominator. First, we find the rasin bagel, which 8/12=4/6=2/3 times the number of plain bagel which is 2/12, or 1/6. 2/3*1/6=2/18=1/9. Tell me if I get it right or not.
Use the function below to find F(3).
F(x) = (1/4)^x
Answer:
The answer is 0.015625
Answer:
Step-by-step explanation:
F(x) = (1/4)^x F(3)
F(3) = (1/4)^3
F(3) = (1/4)×(1/4)×(1/4)
F(3) = 1/64

A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 30 feet more than the length of the shortest side. Find
the dimensions if the perimeter is 198 feet.
What is the length of the shortest side?
The length of the shortest side is
Answer:
The three sides are 36 f t , 72 f t and 59 f t .
Step-by-step explanation:
Let the length of the shortest side of the triangular flower bed be x feet.
Then the length of the second side is 2x and
the length of the third side is x + 23
The given perimeter is 167 f t hence:
x+2x+x+23=167
4x+23=167
4x=167-23
4 x = 144
x = 144 /4 = 36
2 x = 2 ⋅ 36 = 72
x +23 = 36 + 23 = 59
The length of the three sides of the triangular flower bed are 36 f t , 72 f t and 59 f t .

Demetri wakes up at 9:15. It takes him
35 minutes to fold 4 loads of laundry,
35 minutes to bathe the dog, 45 minutes
to bake brownies, and 1 hour to mow the
lawn. After he finishes all of his chores,
he sits down to rest. What time does
Demetri rest?
Answer:
12:10Step-by-step explanation:
We need to add up the times:
35 mins+ 35 mins + 45 mins+ 60 mins= 35+35+45+60= 175 mins
In hours, that would be 2 hrs, and 55 mins
So; 9:15 + 2 hrs and 55 mins= 12:10

Determine if the two triangles shown are similar. If so, write the similarity statement.
Question 16 options:
A)
ΔSUD ∼ ΔTUE
B)
Impossible to determine.
C)
The triangles are not similar.
D)
ΔSUD ∼ ΔEUT
Answer:
C) The triangles are not similar.
Step-by-step explanation:
These triangles are not similar. Similar triangles are triangles with the same angle measurements and proportionate side measures. However, these sides are not proportionate and therefore the triangles are not similar. You can tell the sides are not proportionate because on one triangle the two given sides (which are corresponding with the other two given sides) are congruent but the other triangle has no congruent sides. This also means that the smaller triangle is isosceles while the larger one is scalene, and different triangle types cannot be similar.

Raffle tickets will be sold at an event. The graph shows the amount of revenue, in dollars, the event will raise if different numbers of tickets are sold. 100 How much revenue will the event raise for each raffle ticket sold? 90 А $4.00 80 B $2.00 70 С $1.50 D $0.75 60 Revenue (5) SO 40 30 20 10 4 8 12 16 28 32 20 24 Tickets Sold 36 40
9514 1404 393
Answer:
C. $1.50
Step-by-step explanation:
The graph is a straight line through the origin, so the revenue is proportional to the number of tickets. The ratio of revenue to tickets will tell you the money raised for each ticket sold. Pick any point on the graph and divide the revenue value by the number of tickets.
The division can be easy if the number of tickets is 10. We see that the revenue for 10 tickets is $15, so the amount raised for each ticket is ...
$15/10 = $1.50 . . . . raised per ticket sold

If the sales tax rate is 7.25% in a town in California, then how much would be the full price for a pair of shoes that cost $39
Answer:
Total cost= $41.83
Step-by-step explanation:
Giving the following information:
Purchase price= $39
Tax rate= 7.25% = 0.0725
To calculate the total cost of the pair of shoes, we need to use the following formula:
Total cost= purchase price * (1 + tax rate)
Total cost= 39 * 1.0725
Total cost= $41.83
Solve for x.
X + 9
2x 111
x = [?]
Answer:
120
Step-by-step explanation:
Angle x + 9 and 2x - 111 are adjacent angles.
Adjacent angles are equal.
2x - 111 = x + 9
2x - x = 9 + 111
x = 120
Answer:
2x-111=x+9[corresponding angle]
2x-x=111+9
x=120
