Answer:
C
Step-by-step explanation:
Because of all the variables in the side lengths, we don't have enough information to use side-angle-side similarity.
We do have two angles of one triangle congruent to two corresponding angles of the other triangle, so we can use angle-angle similarity.
Sides AE and AD are corresponding sides. Sides AC and AB are corresponding.
Answer: C

i dont know functions
Answer:
6, -8
Step-by-step explanation:
You need to find out the possible values of which X cannot equal
In fractions the only way that's possible is if the denominator= 0
Because everything in the denominator is being mulitplied this is pretty simple
We need either parantheses to equal 0
so we take them and solve for 0
we have
x-6= 0
x=6
x+8=0
x= -8

find the missing length of 26cm 10cm of the right triangle
Answer:
24cm
Step-by-step explanation:
A^2 + B^2 = C^2 soo 10^ + B^ = 26^2 so 100 + B^2 = 676 subtract 100 from 676. Then take the square root of 576 and you’ll get 24. So B = 24cm

The table shows the test scores and the sleep averages of several students.
a. Write the least squares regression equation that models the data. Let x = hours of sleep and y = test score.
b. Use the equation to determine the approximate test score of a student who sleeps an average of 8 h a night. Show your work.
hey someone else has already answered this!
a. To find the least squares regression equation for a group of (x,y) points:
Step 1: For each point(x,y), we need to calculate x² and xy first.
Step 2: Sum all x, y, x² and xy, which gives us Σx, Σy, Σx² and Σxy
Step 3: Calculate Slope m: m = (NΣxy − Σx Σy)/ N(Σx²) − (Σx)² , here N is the number of data.
Step 4: Calculate Intercept b: b = Σy − m(Σx)/ N
Step 5: Assemble the equation as y= mx+b
Here, we have ∑x = 120, ∑y= 1379, ∑x²= 919.5, ∑xy= 10466 and N= 16
So, m= (NΣxy − Σx Σy)/ N(Σx²) − (Σx)²
=
=
=
= 6.33
and b = Σy − m(Σx)/ N
=
=
=
= 38.71
So, the least squares regression equation is : y= mx+b ⇒ y= 6.33x +38.71
b. When x= 8, then y= (6.33×8)+38.71 = 50.64 + 38.71 =89.35
The approximate test score of a student who sleeps an average of 8 h a night is 89.35%
EVERYTHING IS FROM sicista on brainly!
Answer:
A way to write the least regression equation that models is data y = mx + b => y= 6.33x + 38.71 and as for problem B when X = 8 then y = (6.33 x 8) + 38.71 = 50.64 = 38.71 = 89.35 so the estimated test score of a student who sleeps eight hours a night is equal to 89.39%
Step-by-step explanation:
Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Write an equation to model this situation in the form y = mx + b, but do not
include any spaces in your answers. (for example y=6x+1)
Answer:
55 = 5x
Step-by-step explanation:
Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Write an equation to model this situation in the form y = mx + b, but do not
include any spaces in your answers. (for example y=6x+1)
Equation to model this situation in the form y = mx + b,
y = Total number of stickers she had
x = Number of days that she gave away sticker
b = Fixed value = 0
Hence:
55 = 5x + b
b = Fixed value = 0
Therefore, the situation is represented as:
55 = 5x

Thank you!!!
Answer:
[tex]a_{n} = 8n - 10[/tex]
Step-by-step explanation:
[tex]a_{n} = a_{1} + (n - 1)d[/tex] is the formula you want to use
[tex]a_{n} = -2 + (n - 1)8[/tex]
= -2 + 8n - 8

4y square + y - 45 when y=-5
Given:
The expression is
[tex]4y^2+y-45[/tex]
To find:
The value of the given expression when y=-5.
Solution:
We have,
[tex]4y^2+y-45[/tex]
Putting y=-5, we get
[tex]4(-5)^2+(-5)-45[/tex]
[tex]=4(25)-5-45[/tex]
[tex]=100-50[/tex]
[tex]=50[/tex]
Therefore, the value of the given expression is 50 when y=-5.

Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
