Answer:
See below for answers and explanations
Step-by-step explanation:
A) The midline would be the average of the high and low temperatures, therefore d=(44+26)/2=70/2=35. The amplitude would be the distance from the high and low temperatures to the midline. Since 44-35=9 and 35-26=9, then the amplitude is a=9.
B) The equation would be [tex]T=9sin(\frac{\pi}{12}x)+35[/tex]
The owners of the Syfy channel are interested in whether watching the Syfy channel causes people to become geeky, and whether any such effects depend on a person's gender. They hire a researcher to design and carry out the appropriate study. The researcher asks an equal number of men and women to watch 0, 3, 5, and 9 hours of the Syfy channel each week for 6 weeks. At the end of each week, the researcher measures the geekiness of the men and women on a scale from 1 to 10. How many cells are in this design
Answer:
The number of cells in this design = 4
Step-by-step explanation:
The number of cells in this design are four ( 4 ) and they are
The watchers can be equally geeky regardless of the hours watchedThe watchers can differ in geekiness level across the number of hours watched Women and Men may differ in geekiness levelsMen are geekier than women when watching few hours but less geekier than women when they watch more hours. and Vice versaWhat single decimal multiplier would you use to decrease by 2% followed by a 7% decrease?

answer choices:
A) 14.1 cm
B) 18.8 cm
C) 37.7 cm
D) 75.4 cm
Answer:
B. 18.8cm
Step-by-step explanation:
Circumference = π x Diameter
The given diameter here is 6cm and we need to use 3.14 for π so:
Circumference = 3.14 x 6
Circumference = 18.84 = 18.8 (1.d.p)
Therefore B is correct.

Answer:
B
Step-by-step explanation:
It is B because to find the volume you multiply all three values together, which gets you 68.448. I multiplied 9.2x3.1, which got me 28.52, and then I multiplied 28.52 by 2.4 which got me 68.448.
A cylinder has a height of 20 millimeters and a radius of 20 millimeters. What is its volume? Use s s 3.14 and round your answer to the nearest hundredth.
Answer:
solution given:
height [h]= 20 millimetres
radius [r]=20 millimetres
π=3.14

5.670
56.72
56.27
Answer:
5.670, 56.27,5.72.
Step-by-step explanation:
All you do is pay attention to that decimal and remember that the places where the numbers are present; they are invisible zero so,
56.72 is the same as 56.720000.
It's pretty clear for this question since the numbers are clear so all you do is look at the decimals.
How many degrees is angle y
Answer:
y = 39°Steps:
w = 180 - (85+42) = 180 - 127 = 53°
y = 180 - (88+w)
y = 180 - (88+53)
y = 180 - 141
y = 39°
Answer:
y = 39
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of both triangles , then
x = 42 + 85 = 127
and
y + 88 = 127 ( subtract 88 from both sides )
y = 39
A person hikes 4 miles in 2.5 hours. Find the unit rate in miles per hour.
Answer:
60 miles per hour
Since d=rt, r = d/t = 420 miles/7 hours = 60 miles per hour
Step-by-step explanation:
Answer:
1.6 miles per hour
Step-by-step explanation:
Step one:
The unit rate is the number of miles in 1 hour
given
distance= 4 miles
time= 2.5 hours
so if he hike 4 miles in 2.5 hours
then he will hike x mile in 1 hour
cross multiply we have
x=4/2.5
x=1.6 miles per hours
Therefore the unit rate is 1.6 miles per hour
Answer: 60 miles per hour
