What is the surface area of this triangular pyramid?
___square inches
Answer:
Surface area = 10.7 in.²
Step-by-step explanation:
Surface Area of triangular pyramid = BA + P*L
Base Area (BA) = ½*nh
b = 2 in.
h = 1.7 in.
BA = ½*2*1.7 = 1.7 in.²
Perimeter (P) = 2 + 2 + 2 = 6 in.
Slant height (L) = 3 in.
Plug in the values
Surface Area = 1.7 + ½*6*3
Surface area = 10.7 in.²

Let be a1 = 8 and a2 = 8 [ From question ]
We have to find out common differences which denoted by letter d .
d = a2 - a1 [ Formula ]
= 8 - 2
= 6
Thus,the common difference between successive terms in the sequence is 6 .
Answer:
6.
Step-by-step explanation:
We have to find out common differences which denoted by letter d .
d = a2 - a1 [ Formula ]
= 8 - 2
= 6
Also,
2+6=8 +6=14 +6=20 +6=26
So, It's Added Up By 6.
For each of the following research scenarios, decide whether the design uses a related sample. If the design uses a related sample, identify whether it uses matched subjects or repeated measures.
John Cacioppo was interested in possible mechanisms by which loneliness may have deleterious effects on health. He compared the sleep quality of a random sample of lonely people to the sleep quality of a random sample of nonlonely people.
The design described_______________ .
A researcher is interested in whether people eat more or less when they are in a hurry. The researcher collects a random sample of 80 adults and invites them to eat two (identical) free meals one month apart. For one of the meals, no time restriction is placed on the meal. For the other meal, participants are told when their meal is served that they have only 10 minutes until another group is due to sit down. Half of the participants eat their hurried meal first; the other half eat it second. The researcher compares the amount eaten at each sitting.
The design described_______________ .
Answer:
Step-by-step explanation:
From the first scenario, John Cacioppo is studying two independent samples of lonely and non-lonely people.
Thus, the design explained in the first scenario does not use a related sample.
The second scenario uses a related sample(repeated measures).
Since the same sample is measured at different times, hence samples are related and repeated measurement is used.
20. Find the equation of the straight line bisercting the line joining the points (3,4) and(5,6) if it
slope is 2
Answer:
pretty sure the answer is x - y - 1 = 0
What is the slope of the line plotted below?
O A. 0.25
B. -0.25
O C. -0.5
O D. 5
Answer:
m= -0.25 b=2.25 the answer is -0.25
A slope is also known as the gradient of a line. The slope of the line is -0.25. The correct option is B, -0.25.
What is Slope?A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
slope = (y₂-y₁)/(x₂-x₁)
The two points of the graph are given as (-3,3) and (1,2). Now, the slope of the line can be written as,
Slope = (3 - 2) / (-3 - 1)
= 1/-4
= -0.25
Hence, the slope of the line is -0.25.

What is the area?
30
32 in
Step-by-step explanation:
Here's your solution
=> Base = 32 In
=> Height = 30 in
=> Area of traingle = 1/2*base *height
=> putting the value of base and height in formula
=> Area = 1/2*30*32
=> Area = 480 in sq

Find the value of x and the value of y
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
use Cos for y .... b/c we see that function above has all the pieces we are going to work with
use Sin for x .. for the same reason above
Cos(30) = y / 4[tex]\sqrt{2}[/tex]
4[tex]\sqrt{2}[/tex]Cos(30) = y
4[tex]\sqrt{2}[/tex][tex]\sqrt{3}[/tex]/2 = y
2[tex]\sqrt{6}[/tex] = y
leave the answer for y like that.. it's in 'exact" form
now for x
Sin(30) = x / 4[tex]\sqrt{2}[/tex]
4[tex]\sqrt{2}[/tex]Sin(30) = x
4[tex]\sqrt{2}[/tex]* 1/2 = x
2[tex]\sqrt{2}[/tex] = x
and leave your answer for x like that as it's in it's exact form. :)
oh and I see the answer in the list.. do you? :)

22. A husband and a wife apprear in an interview for two vacancies for the same post.The probability of husband's selection is 3÷5 and that of wife's selection is 1÷5. Find the probability that:
(i) both are selected
2) exactly one is selected
3) none is selected
Answer:
[tex]P(Both) = \frac{3}{25}[/tex]
[tex]P(One) = \frac{12}{25}[/tex]
[tex]P(None) = \frac{22}{25}[/tex]
Step-by-step explanation:
Given
[tex]P(H) = \frac{3}{5}[/tex]
[tex]P(W) = \frac{1}{5}[/tex]
Solving (a): Both selected
[tex]P(Both) = P(H) * P(W)[/tex]
[tex]P(Both) = \frac{3}{5} * \frac{1}{5}[/tex]
[tex]P(Both) = \frac{3}{25}[/tex]
Solving (b): One selected.
This event can be represented as: HW' or H'W
So:
[tex]P(One) = P(H) * P(W') + P(H') * P(W)[/tex]
Where:
P(W') = 1 - P(W) and P(H') = 1 - P(H).
So:
[tex]P(One) = \frac{3}{5} * \frac{4}{5} + \frac{2}{5} * \frac{1}{5}[/tex]
[tex]P(One) = \frac{12}{25} + \frac{2}{25}[/tex]
[tex]P(One) = \frac{12}{25}[/tex]
Solving (c): None selected.
This is the complement of (a) above.
i.e.
[tex]P(None) = 1 - P(Both)[/tex]
[tex]P(None) = 1 - \frac{3}{25}[/tex]
[tex]P(None) = \frac{25 - 3}{25}[/tex]
[tex]P(None) = \frac{22}{25}[/tex]

Reasoning : Why is the numerator greater than
the denominator in a fraction that is equivalent
to a percent greater than 100?
Answer:
See the explanation
Step-by-step explanation:
When the numerator is less than the denominator, the result is always less than 1, that is 0. something and this will give a percentage less than 100, but when the numerator is greater than the denominator, th result is greater than 1, and any figure greater than 1 gives a percentage that is greater than 100
example
Numerator >Denominator
=4/2*100
=2*100
=200%
Numerator <Denominator
=2/4*100
=0/5*100
=50%

What is the population in 2020 of a place that has a population of 4 million people in 2011 and is growing at a rate of 1.3%?
Answer:
370 million
Step-by-step explanation:
In the 10 years from 2000 to 2010, the population was multiplied by the factor ...
100% + 9.6% = 109.6% = 1.096
In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:
2030 population = (308 million)·(1.096²) ≈ 370 million

Answer:
Step-by-step explanation:
I'll assume that all the angles are 90°, and there is no bottom to the box.
To determine the wood needed, calculate the surface area of the bed. Since there is no bottom or top to the box, the amount of wood is 2(45 in × 21 in) + 2(22 in × 21 in) = 1890 in² + 924 in² = 2814 in²
To determine the soil needed, calculate the volume of the box.
volume = 45 in × 21 in × 22 in = 20,790 in³
