Answer:
0.89417
Step-by-step explanation:
Using the relation to obtain the Zscore :
Z = (x - mean) ÷ standard deviation / sqrt(n)
x = 0.8535
Mean = 0.8565
Standard deviation = 0.0518
Sample size, n = 465
P(x ≤ 0.8535) = (0.8535 - 0.8565) ÷ 0.0518/sqrt(465)
P(x ≥ 0.8535) = - 0.003 / 0.0024021
P(x ≥ 0.8535) = - 1.249
P(Z ≥ - 1.249) = 0.89417

PLEASE HELP IM STRESSED I CANT THANK YOU :)
Answer:
125
Step-by-step explanation:
In ΔPTO we are given that
∠PTO = 90° (indicated by the right angle)
and ∠TPO = 35°
And we need to find the exterior angle (∠TOB)
If you didn't know this is the rule about exterior angles
Exterior angles of a triangle are equal to the sum of the opposite interior angles of a triangle
So more specifically for this problem
∠TOB = ∠PTO + ∠TPO
Now that we have created an equation we want to plug in the values that we are given
∠TOB = 90 + 35
90 + 35 = 125
Therefore the answer is 125
The areas of two similar squares are 16m2 and 49m2 what is the scale factor of their side lengths
Given:
The areas of two similar squares are 16m² and 49m².
To find:
The scale factor of their side lengths.
Solution:
We know that the ratio of the areas of the similar squares is proportional to the ratio of square of there sides.
[tex]\dfrac{\text{Area of first square}}{\text{Area of second square}}=\dfrac{(\text{Side length of first square})^2}{(\text{Side length of second square})^2}[/tex]
[tex]\dfrac{16\ m^2}{49\ m^2}=\dfrac{s_1^2}{s_2^2}[/tex]
[tex]\dfrac{4^2}{7^2}=\left(\dfrac{s_1}{s_2}\right)^2[/tex]
[tex]\left(\dfrac{4}{7}\right)^2=\left(\dfrac{s_1}{s_2}\right)^2[/tex]
Taking square root on both sides, we get
[tex]\dfrac{4}{7}=\dfrac{s_1}{s_2}[/tex]
[tex]\dfrac{s_1}{s_2}=\dfrac{4}{7}[/tex]
Now, the scale factor is the ratio of side length of second square to the side length of first square.
[tex]k=\dfrac{s_2}{s_1}[/tex]
[tex]k=\dfrac{7}{4}[/tex]
Therefore, the scale factor of their side lengths is [tex]k=\dfrac{7}{4}[/tex].
Answer: 4/7 is the right answer on Acellus
Step-by-step explanation:
After eight games the team has won two games lost five and tied one if there season is 24 games how many games will they win at this rate
Answer:
Since the games in total add up to 8, we see that 8 is a factor of 24. It goes in 3 times. Therefore, we have to multiply everything by 3 to get the answer out of 24. There will be 6 wins, 15 losses and 3 tie. That adds up to 24.

The fourth term in an arithmetic sequence is 18 and the seventh term is 39. If the first term is a1 , which is an equation for the nth term of this sequence?
Answer:
aₙ = 7n - 10Step-by-step explanation:
The nth term: [tex]a_n=a_1+d(n-1)[/tex]
So:
a₄ = a₁ + 3d
18 = a₁ + 3d ⇒ 3d = 18 - a₁
a₇ = a₁ + 6d
39 = a₁ + 6d
39 = a₁ + 2(18 - a₁)
39 = a₁ + 36 - 2a₁
39 = 36 - a₁
a₁ = -3
3d = 18 - (-3)
3d = 21
d = 7
So the nth term:
[tex]a_n = -3 + 7(n-1)\\\\a_n=-3 +7n - 7\\\\a_n = 7n - 10[/tex]

Answer:
A = x² + 11x + 30
Step-by-step explanation:
For a given rectangle
Length (l) = x + 5
Breadth (b) = x + 6
Now,
Area of rectangle
A = l × b
= (x + 5) × (x + 6)
= x² + 6x + 5x + 30
A = x² + 11x + 30
Thus, The area of rectangle in the form of polynomial is
x² + 11x + 30

Does the following infinite series converge or diverge? 1/3+2/9+4/27+8/81
Answer:
converge
Step-by-step explanation:
The ratio that you multiply by to get the next term is 2/3, which is less than 1, so the geometric series converges by the Geometric Series Test.
Answer:
Converge
Step-by-step explanation:
The value of r in this infinite series is 2/3.
If the absolute value of r is less than 1, then the infinite series converges.
Since 2/3 is less than 1, the series must converge.

Solve x2 + 8x = 24.
Answer:
-10.3 and 2.3
Step-by-step explanation:
use quadratic formula:
-8 ± √8²-4(-24) ÷ 2
= -8 ±√64+96 ÷ 2
= -8 ± √160 ÷ 2
= -8 + 4√10 / 2 and
-8 - 4√10 / 2
which is the same as -4 + 2√10 and -4 + 2√10
which is the same as -10.3 and 2.3

Robert is baking desserts for a picnic. He needs to make at least 20 servings of dessert for the
event. For every batch of brownies he bakes, he will get 8 servings, and every pie will
yield 14 servings.
Answer:
x*8 + y*14 ≥ 20
Step-by-step explanation:
We know that:
A batch of brownies makes 8 servings.
A pie makes 14 servings.
He wants to make, at least, 20 servings.
Then if he makes x batches of brownies, he will get x times 8 servings.
If he makes y pies, he will get y times 14 servings.
Adding that, he will get a total of:
x*8 + y*14 servings
And because he wants to make at least 20 servings (he can make 20 or more)
The inequality will be:
x*8 + y*14 ≥ 20
Where the "≥" symbol means that the expression at the left is greater than or equal to the expression of the right

Answer:
(5,-6) and (-5,-6) is the correct answer
Step-by-step explanation:
Eliminate incorrect answers
(-2,8)and (2,-8) are in the opposite direction not mirroring each other
(-7,-1) and (-7,1) are on the same x axis but to close to the y axis not mirroring
(4,-3) and (-3,4) is completely off and not mirroring
* Remember the first number in the parentheses moved on the x axis then the y
