Answer:
44dgrees
Step-by-step explanation:
Find the diagram attached
Given from the diagram;
Hypotenuse XZ = 18
Adjacent XY = 13
Required
m<X
Using the SOH CAH TOA identity
cos theta = adjacent/hypotenuse
cos m<X = XY/XZ
cos m<X = 13/18
m<X = arccos(13/18)
m<X = arccos(0.72222)
m<X = 43.7
m<X ≈ 44degrees
Hence the measure of m<X to the nearest degree is 44degrees

Which statement is true about the graph y = - 3x + 2
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]y = -3x + 2[/tex]
Required
The true statement
The question is incomplete, as no option is given.
I will solve generally, as follows;
A linear equation is represented as:
[tex]y =mx+b[/tex]
Where
[tex]m \to[/tex] slope
[tex]b \to[/tex] y intercept
So, by comparison:
[tex]m = -3[/tex]
[tex]b = 2[/tex]
Hence, the graph has a slope of -3 (a negative slope)
And the y intercept of 2

Answer:
arc FG = 115°
arc EG = 165°
Step-by-step explanation:
The first step is to understand how these arcs are arranged on a circle. The next step is to realize the whole is the sum of the parts. Arcs have the same measure as their central angle. A circle totals 360°.
arc EF + arc FG = arc EFG . . . . parts of an arc add to give the whole arc
80° + arc FG = 195°
arc FG = 115° . . . . . . . . . subtract 80°
__
Similarly, parts of a circle add to give the whole circle.
arc EFG + arc EG = 360°
195° + arc EG = 360°
arc EG = 165° . . . . . . . . . subtract 195°
The makers of a certain diet cola claim that its taste is identical to the full-calorie version. To test this claim, a
researcher recruits 175 volunteers, has them drink samples of both colas from identical cups in a randomized order,
and then asks them to identify which sample is the diet cola. If we assume that the volunteers truly cannot tell the
difference, then the probability that they correctly identify the diet cola is 0.5.
X = the number of volunteers who correctly identify the diet cola and is a binomial random variable.

What is the total of the surface are of this figure
Answer:
answer: 200
Step-by-step explanation:
Finding surface area for triangles is base × height ÷ 2 So 10 x 10 = 100 100 ÷ 2 = 50 sense all of these triangles are identical we just have to multiply 50 with the number of triangles so
50 × 4 = 200 So 200 is our answer. Hope this helps!

A fireman needs to get water to a second-floor fire. His ladder is 30 ft long and he leans it against the vertical wall so that the top of the ladder is 27 ft above the ground.
(a) Use trigonometry to find the angle formed between the ground and the ladder. Round to the nearest whole number and show all your work.
(b) For safety reasons, the fireman wants the angle the ladder makes with the ground to be no more than 70°
Will the ladder be safe the way it is positioned?
Answer:
(a) 64°
(b) Yes, the ladder will be safe the ingredients will be used.
Step-by-step explanation:
(a) Trigonometric function of Sine is the appropriate formula to use to solve this question. The formula is given as:
sin θ = Opposite/Hypotenuse
θ = Angle formed with the ground = ?
Opposite = 27 ft
Hypotenuse = 30 ft
Hence,
sin θ = 27 /30
θ = arc sin (27/30)
θ = 64.158067237°
Approximately to the nearest whole number = 64°
(b) From the above calculation, the angle the ladder makes with the ground is 64° and now we want that angle to be 70°
64° is less than 70=
64° < 70°
Hence, the ladder will be safe the way it is positioned.

Step-by-step explanation:
Answer:

Step-by-step explanation:
2x - 1/4 + x/3 = 2
2x + x/3 = 2 1/4 (added 1/4 to both sides)
6x = 6.75 (multiplied both sides by 3)
x = 1 1/8, or 1.125

Mika is a local farmer who is interested in how often residents in her town go to a farmer's market each month. She surveys 124 families and finds that, on average, those families visit a farmers' market 4.2 times per month with a sample standard deviation of 1.3. If Mika wants to be 99% confident (z=2.58) using this sample, what should her margin of error be and what does it mean?
Answer:
The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.
Step-by-step explanation:
Margin of error
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Standard deviation of 1.3
This means that [tex]\sigma = 1.3[/tex]
She surveys 124 families
This means that [tex]n = 124[/tex]
Margin of error and meaning:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 2.58\frac{1.3}{\sqrt{124}}[/tex]
[tex]M = 0.3012[/tex]
The margin of error is of 0.3012, and it means that we should be 99% confident that the population mean would be within 0.3012 of the sample mean.

Answer:
b
Step-by-step explanation:

If Henry decides to mow lawns then the opportunity cost would be - the chance to earn by working in a library
The correct answer is an option (B)
What is opportunity cost?"It is the value of what you lose when choosing between two or more options.""It is the value of the next best option."We know that,
the opportunity cost is the cost of the alternative that we waive when we make a certain decision, including the benefits that we could have obtained from having chosen the alternative option.It is referred to as "the value of the best option not selected".The opportunity cost is the values that are lost while choosing one alternative in place of others.This value may or may not be measured in money.It is the value of what you have to give up in order to choose something else.Henry wants to get a job this summer.
He can either mow lawns or work in the local library.
if he decides to mow lawns, he would lost the chance to earn by working in a library.
This means, the opportunity cost is - the chance to earn by working in a library
Therefore, if Henry decides to mow lawns then the opportunity cost would be - the chance to earn by working in a library

Find the volume of the cylinder. Round your answer to the nearest hundredth of a cubic meter.
Answer:
I think that the answer may be volume = 169.65
Step-by-step explanation:
The volume of cylinder whose radius 3m and height 6m is 169.56 cm³ ≈ 170 cm³
What is Volume of Cylinder?The volume of a cylinder is the density of the cylinder which signifies the amount of material it can carry or how much amount of any material can be immersed in it. Cylinder’s volume is given by the formula, π[tex]r^2h[/tex], where r is the radius of the circular base and h is the height of the cylinder.
Here, Radius of Cylinder = 3 m.
Height of Cylinder = 6 m.
Volume of Cylinder = πr²h
= 3.14 X 3 X 3 X 6
= 169.56 cm³
≈ 170 cm³
Thus, the volume of cylinder whose radius 3m and height 6m is 169.56 cm³ ≈ 170 cm³.
