PLEASE HELP !!! i need to know the surface area
Answer:
244 ft²
Step-by-step explanation:
Rectangle Base Area: 6•4=24
Rectangle Side Area: 8•10=80; 80•2(sides) = 160
Triangle Sides Area: (10•6=60); 60/2(area of triangle) = 30; 30•2(sides)=60*
*Technically can skip the divide by two and then multiply by two, since they cancel out*
(Area of Triangle Formula= 1/2bh)
Add areas together: 24+160+60= 244 ft²
An experiment was conducted as a one-way factorial design with K sample means, each based on n scores. What is the number of degrees of freedom for the between mean squares
Answer:
The mean squares has d.f (n-1)
Step-by-step explanation:
The total number of degrees of freedom is n-1 as there is only one restriction of computing the grand mean. The d.f for k samples is k-1 beacuase the mean of the sample means must equal the grand mean. Similarly , the d.f for within SS is n-k , due to the k restrictions of computing the k sample means. Hence we find that
Total df= Within df + Between df
n-1= (n-k)+(k-1)
Between SS has (k-1) d.f
Within SS has (n-k) d.f
These two quantities are known as mean squares and has d.f (n-1)

Given that z is a standard normal random variable, find the value of z for each situation. a. The area to the right of z is 0.01.
Answer: =1.34
Step-by-step explanation:
In standard density curve
P(Z<z) = Area left of z, P(Z>z) = area right of z.
P(Z<z) +P(Z>z) =1
Given: z is a standard normal random variable.
To find : value of z if rea to the right of z is 0.01.
i.e. P(Z>z) =0.01
P(Z<z) =1-0.01 = 0.09
from z-score table, z value for this is 1.34.
Hence, z= 1.34

There are 10 girls for every 12 boys. If there are 50 girls,
how many boys are there?
O a) 60
Ob) 12
O c) 52
d) 62
Answer: A
why does this keep changing to C????
Step-by-step explanation:
10x5 since there are 50 girls
so we would need to multiply 12 by the same number, so the answer is 60.
1. A hummingbird weighed w ounces. One day the hummingbird drank 8 times its weight
in water and ate half its weight in food. Which equation can be used to find t, the
combined weight of the water and the food, In ounces, that the hummingbird had on this
day?
O
t - W + 8
2
O
t-w + 8 +
NI
O
t =8w+
2
w
t2w+
8
CLEAR ALL
Answer:
t = 8w + w/2
Step-by-step explanation:
Given that :
Weight of bird = w
Amount of water consumed = 8*w = 8w
Amount of food ate = 0.5*w = 1/2w
Hence, the combined weight of water and food (t) consumed by the humming bird :
t = amount of water consumed + amount of food ate
t = 8w + w/2

What is the exact value of cos(11pi/12)
9514 1404 393
Answer:
[tex]\text{(a)} \quad -\dfrac{\sqrt{2+ \sqrt{3}}}{2}[/tex]
Step-by-step explanation:
The angle is near π, so the cosine value is a negative value near -1. This means the value under the numerator radical must be slightly less than 4. The only answer choice that makes any sense is the first choice.
The value of the cosine is ...
cos(11π/12) ≈ -0.9659
The values of the answer choices are ...
a) -0.9659 . . . . matches the required value
b) -0.2588
c) 0.2588
d) 0.9659
_____
You could use half-angle or angle sum formulas to figure this exactly, but it is much easier to make a multiple-choice selection based on your general knowledge of the cosine function and √3 (≈1.73).

Answer:
Either a tangent line or a line parallel to the axis of symmetry will do.
A standard high school parabola has a vertical or horizontal axis of symmetry, so a line of the form x=k or y=k is the easiest way

Answer:
-7x^3+8x^2+x-5
Step-by-step explanation:
We are simply adding the two functions:
f(x) + g(x) = (2x^2-5x^3+x-7) + (6x^2-2x^3+2) = 8x^2-7x^3+x-5 = -7x^3+8x^2+x-5
Write the equation of the line in slope-intercept form.
Answer: y=-3/4x
Step-by-step explanation:
The slope intercept form is when you use the equation y=mx+b (m is the slope and b is the y-intercept). First, let's find the y intercept. The y intercept is what y would be if x is 0. here, you can see that this particular line passes through the origin. So, the y-intercept is zero because when x passes through zero, y is also zero. Next, let's find the slope. The formula for slope is change in y/change in x. Let's randomly choose 2 points off this line. To make this a thousand times easier for us, let's choose the points (-4, 3) and (4, -3). Now, to find the change in y, let's find the difference between the 2 y coordinates we have chosen. To do this we just need to do -3-3, which gives us -6. Now let's find the change in x. To do this we will do the same thing we did to find the change in y but this time we'll use the x coordinates. We will do 4-(-4), which simplifies to 8. Now, we're almost done. Just divide the change in y by the change in x. You will get -6/8. This can be simplified to -3/4. So now we know our slope is -3/4 and our y-intercept is 0. Let's insert them into the equation. y=-3/4x+0. We know that we can just get rid of that 0 because 0 literally means nothing. So our final answer is y=-3/4x. Hope this helps!

Given: wzx and yzx are right triangles, wx = yx. Prove wxz ~= yx .....plz answer will give brainlyest!!
Answer:
The answer is below
Step-by-step explanation:
From the question,
Statement Reason
ΔWZX and ΔYZX are Given
right angled triangles
WX = YX Given
XZ ≅ XZ Reflexive property. The reflexive
property of congruence states that
any shape is congruent to itself.
∠XZW = ∠XZY Definition of right angle.
∠XWZ = ∠XYZ Definition of isosceles triangle.
Triangle XYW forms a right angled
triangle since YX = WX
∠XWZ + ∠WXZ + ∠XZW = 180° Sum of angles in triangle WZX
∠XZY + ∠XYZ + ∠YXZ = 180° Sum of angles in triangle YZX
∠XWZ + ∠WXZ + ∠XZW = Substitution
∠XZY + ∠XYZ + ∠YXZ
∠XYZ + ∠WXZ + ∠XZY = Substitution
∠XZY + ∠XYZ + ∠YXZ
∠WXZ = ∠YXZ Simplification
what has a quotiont of 9 and a reminder of 5
Answer:
Division problems with quotient of 9 and remainder of 5 could include:-
23/2 = 9 + 5/2
32/3 = 9 + 5/3
41/4 = 9 + 5/4
50/4 = 9 + 5/5
But you could justifiably object that more natural forms for the answers would be 11 + 1/2, 10 + 1/3, 10 + 1/4 and 10 , and so you may well prefer such as
59/6 = 9 + 5/6
77/8 = 9 + 5/8 ….. and so on
As you can see the general pattern is (9n + 5)/n = 9 + 5/n
You can now make up your own examples, like 212/23 = 9 + 5/23
