Marko's heart beats 72 times per minute during normal activity. It beats 65 times
per minute during sleep, and 118 times per minute when Marko is exercising.
During a 24-hour period, Marko slept from 10:00 p.m. until 5:00 a.m. and then
exercised from 5:30 a.m. to 7:30 a.m. For the remaining time he had normal
activity. During that 24-hour period, how many times did Marko's heart beat?
(times)
Answer:
105,660 times
Step-by-step explanation:
7 times 65=445 times 60=26 700
2 times 118=236 times60=14 160
15 times 72=1080 times 60=64 800
26700 plus 14 160 plus 64 800=105,660
brainliest please
Answer:
105,540 beats
Step-by-step explanation:
10:00-5:00 is 7 hours long so
60(minutes)×7=420 minutes
since his heart beats 65 times/min.
420×65=27,300 beats
5:30-7:30 is 2 hours long so
60(minutes)×2=120 minutes
120×118=14,160 beats
7 hours+2 hours=9 hours
24-9=15 hours
60×15=900 minutes
900×72 beats=64,800 beats
Add all heart beats together
27,300+14,160+64,080=105,540

3. National Discount has 260 retail outlets throughout the United States. National evaluates each potential location for a new retail outlet in part on the mean annual income of the households in the marketing area of the new location. National develops an interval estimate of the mean annual income in a potential marketing area after taking a random sample of households.For a marketing area being studied, a sample of 36 households was taken and the sample mean income was $21,100.39. Based on past experience, National Discount assumes a known value of $4500 for σ=the population income standard deviation.a. Develop a 95% confidence interval for the mean annual income of households in this marketing area. (5 point)
Answer:
(19630.39 , 22570.39)
Step-by-step explanation:
Given that:
Mean, m = 21100.39
Standard deviation, σ = 4500
Sample size, n = 36
Zcritical at 95% = 1.96
Confidence interval (C. I) :
m ± Zcritical(σ/√n)
21100.39± 1.96(4500/√36)
Lower bound :21100.39 - 1.96(750) = 19630.39
Upper bound : 21100.39+1.96(750) = 22570.39

Step-by-step explanation:
The lines represent the lines of symmetry where the image can be reflected upon. Hence it is reflectional.
The dot in the middle of the image tells us that the image can be rotated about the dot to produce the exact same image. Hence it is rotational.
The answer is both rotational and reflectional.
Answer:
I broke it to phrases. Make sure to read both.
It is rotational symmetry. This is because rotational symmetry means it is able to be rotated, and looks the same. This is true with this figure. The lines demonstrate that it is an equal dimensioned 2D shape.
It is ALSO reflection symmetry because this means it can be split through the center and looks exactly the same, as if it was a reflection. This is true here too because it has the same amount of lines split through the same angle on each side making it equal. You can also see a line already going through the shape, and as you can see if you look at see side it looks equal, like a reflection.
The answer is D.

How do the ideas in the sidebar differ from the rest of the article, and how are they related to its overall ideas?
Answer:
What Is a Sidebar? A sidebar is a block of supplemental text that appears next to a main article in a magazine, newspaper, or website. It relates to, expands, and adds value to the article it accompanies
First, a sidebar can be used to encourage the reader to read the more detailed main article. For example, a sidebar can be made that lists the major points of the main article or asks questions about information that will be given in the main article as a way to entice readers to read the entire main article.

Explanation:
Bill Ding plans to build a new hardware store. He buys a rectangular lot that is 50 ft by 200 ft, the 50-ft dimension being along the street. The store is to have 4000 ft2 of floor space. Construction costs $100 per linear foot for the part of the store along the street and only $80 per linear foot for the parts along the sides and back. To what dimensions should Bill build the store to minimize construction costs
Answer:
Length a = 59.62
Width b = 67.09
Cost = $10,734.4
Step-by-step explanation:
Solution:
Let a be the length and b be the width.
Area of the rectangle = a x b
a x b = 4000
Cost of the construction:
Cost = 100a + 80(a + 2b)
Cost = 100a + 80a + 160b
Cost = 180a + 160b Equation of the Cost of the construction.
Now, we need a and b to calculate the minimum cost required to build a lot.
From the area = a x b
we have,
a x b = 4000
b = 4000/a
Putting this equation into the cost of the construction.
We get:
Cost = 180a + 160 x (4000/a)
Cost = 180a + 640000/a
Differentiating with respect to a, we get
[tex]C^{'}[/tex] = 180 - 640000/[tex]a^{2}[/tex]
Putting [tex]C^{'}[/tex] = 0
180 - 640000/[tex]a^{2}[/tex] = 0
Taking LCM
180[tex]a^{2}[/tex] - 640000 = 0
Solving for a
180[tex]a^{2}[/tex] = 640000
[tex]a^{2}[/tex] = 640000/180
[tex]a^{2}[/tex] = 3555.55
Taking square root
a = 59.62
As we know,
b = 4000/a
putting the minimum value of a = 59.62
b = 4000/59.62
b = 67.09
So, now we have both the dimensions a and b
Putting the values of a and b we will get the cost of the construction.
Cost = 180a + 160b
Cost = 180(59.62) + 160(67.09)
Cost = $10,734.4
Hence, $10,734.4 will be the minimum cost of the construction for Bill Ding.

Your balance sheet shows $6,400 worth of inventory in hair products. Items are recorded in inventory at cost, and the average cost per unit is $2.43. How many units of hair products do you have ?
Answer:
Units of hair products = 2634 units
Step-by-step explanation:
Given that:
Worth of products in the inventory = $6400
Average cost per unit = $2.43
Number of units = [tex]\frac{Total\ worth}{Per\ unit\ cost}[/tex]
Number of units = [tex]\frac{6400}{2.43}[/tex]
Number of units = 2633.73
Rounding off to nearest whole number = 2634 units
Hence,
Units of hair products = 2634 units
