An observational study of 2,391 people aged 65 or over was conducted. The researchers found that those who attended weekly religious services in person were 40% less likely to have high blood pressure than those who stayed home and watched the same weekly religious services via internet streaming. Which of the following is a valid conclusion?
a. There could be lurking variables such as pre-existing health conditions.
b. Watching religious services via web streaming is boring and unhelpful.
c. Attending weekly religious services in person causes lower blood pressure.
d. We cannot make any conclusions because the study only included people aged 65 or over.
Answer:
c. Attending weekly religious services in person causes lower blood pressure.
Step-by-step explanation:
From the study carried out about those who are 65 years and above but attending religious services in person rather than watching it online, it was able to show that, blood pressure is reduced.
This is because, they would walk before entering the religious service building as well as engage a little strenous exercise like dancing, singing etc which helps to put their body system in working state. On the other hand, those who watch it online became increasingly exposed to blood pressure due to their sedentary lifestyles of not moving around.
Express the following measure in radians.
675°
Answer:
[tex]\frac{15\pi }{4}[/tex]
Step-by-step explanation:
Degrees to radians, multiply by pi/180
675pi/180
use a calculator to simplify
You get 15pi/4
The value of 675 degree is equivalent to [tex]\frac{15pi}{4}[/tex].
What is the formula to convert degree to radian?
The relation between radian and degree is given by Angle in radian=angle in degree*[tex]\frac{pi}{180}[/tex].
What is the conversion of 675degree?We will substitute 675 for angle in degree into the formula to get the value in radian.
[tex]\frac{675*pi}{180}[/tex]
This will be [tex]\frac{15pi}{4}[/tex].
Therefore, the correct answer is [tex]\frac{15pi}{4}[/tex].

A quadratic polynomial which has zeros at -7 and 5. ?
Answer:
x^2 + 2x - 35
Step-by-step explanation:
Sum of zeros
= - 7 + 5
= - 2
Product of zeros
= - 7 x 5
= - 35
x^2 - ( sum of zeros )x + product of zeros
= x^2 - ( - 2 ) x + ( - 35 )
= x^2 + 2x - 35
The Quadratic polynomial is x^2 + 2x - 35.
What's the pattern of 1, 2, 4, 5, 7, 8, 10
Answer:
U add 1 then add 2 for each number
Answer:
+1 then +2
Step-by-step explanation:
We are given a sequence of 1, 2, 4, 5, 7, 8, 10 and are asked to find the pattern.
To solve, we need to see how much is being added into every single number.
1, 2
+1
2, 4
+2
4, 5
+1
5, 7
+2
We see that there is a repetition of +1 and then +2.
Therefore the pattern is +1 then +2

What is a rectangular prism?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
We have a composite figure shown in the picture.
As we can see in the picture the composite figure is made up of two figures.
The first one is a rectangular prism
Second one is a triangular prism.
The surface area of the composite figure:
= area of the two triangle shapes + area of the two rectangles in triangular prism + surface area of the rectangular prism - (12x5)
= 2(1/2)12x10 + 2(10x5) + 2(4x5 + 12x5 + 12x4) - 12x5
= 120 + 2(50) + 2(20 + 60 + 48) - 60
= 120 + 100 + 2(128) - 60
= 120 + 100 + 256 - 60
= 416 square cm
Thus, the surface area of the composite figure is 416 square cm because the composite figure is made up of two figures.

PLEASE HELP!!!!! PLEASE GIVE A EXPLANATION AND SHOW WORK!!!! THANK YOU!!!!
In 2018, the population will grow to over 700,000. The population of a city in 2010 was 450,000 and was growing at a rate of 5% per year. In what year will the population be over 700,000? Show all work.
Answer:
2019
Step-by-step explanation:
2010: 450,000
2011: (5% of 450,000) + 450,000 = 472,500
2012: (5% of 472,500) + 472,500 = 496,125
2013: (5% of 496,125) + 496,125 = 520,931.25
2014: (5% of 520,931.25) + 520,931.25 = 546,977.8125
2015: (5% of 546,977.8125) + 546,977.8125 = 574,326.703125
2015: (5% of 574,326.703125) + 574,326.703125 = 603,043.038281
2016: (5% of 603,043.038281) + 603,043.038281 = 633,195.190195
2017: (5% of 633,195.190195) + 633,195.190195 = 664,854.949705
2018: (5% of 664,854.949705) + 664,854.949705 = 698,097.69719
2019: (5% of 698,097.69719) + 698,097.69719 = 733,002.582049
Basically, take five percent of the population of the year and add it to the population of the previous year. This is the long way of doing it, but you get the population count for each year.

Consider two stocks. Stock 1 always sells for $10 or $20. If stock 1 is selling for $10 today, there is a .80 chance that it will sell for $10 tomorrow. If it is selling for $20 today, there is a .90 chance that it will sell for $20 tomorrow. Stock 2 always sells for $10 or $25. If stock 2 sells today for $10, there is a .90 chance that it will sell tomorrow for $10. If it sells today for $25, there is a .85 chance that it will sell tomorrow for $25. On the average, which stock will sell for a higher price? Find and interpret all mean first passage times.
Answer:
On stock 2 will be has an average sell of $50 for higher price.
Step-by-step explanation:
stock 1 of $10 (today)+ $10 (80% chance tommorow)=$20 stock sell price and for $20(today)+$20(90% chance tommorow)= $40 this two final of price for stock 1.
Stock 2 of $10 (today)+$10(90% chance tommorow)= $20 and of $25(today)+$25(85% chance tomorrow)= $50 this two for final of it's price for stock 2.So as for Stock 2 has the average sell higher price.
