Answer:
(2x+3)(x-5)
Step-by-step explanation:
Given the expression 2x²-7x-15
Factorize
2x²-10x+3x-15 =0
2x(x-5)+3(x-5)
(2x+3)(x-5)
Hence the factored form of the expression is (2x+3)(x-5)

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
well you know it's a 90° so do you know what Sin(90) is? you should :D
I think this is kinda a trick question too b/c Opp here is also Hyp
so it would like like sin(90) = Opp / Hyp but that's 427/427 for this question. seems kinda confusing why ask it that way.. huh :/
sin(90) = 1

Suppose a sample of 256 was taken from a population with a standard deviation of 64 centimeters. What is the margin of error for a 68% confidence interval?
A. 6
B. 8
C. 10
D. 4
The correct margin of error for a 68% confidence interval is option D 4 centimeters.
Let's calculate the margin of error correctly for a 68% confidence interval.
To calculate the margin of error, we need to determine the critical value associated with a 68% confidence interval. For a normal distribution, the critical value is approximately ±1 standard deviation.
Given that the standard deviation is 64 centimeters, the margin of error can be calculated as:
Margin of Error = 1 * (Standard Deviation / √Sample Size)
= 1 * (64 / √256)
= 1 * (64 / 16)
= 1 * 4
= 4
Therefore, the correct margin of error for a 68% confidence interval, based on the given information, is 4 centimeters. The correct answer is option D.

2x = 5
5x = 15
5x + 6 = 21
Answer:
7x-2=19
5x=15
5x+6=21
................
Step-by-step explanation:
Here x = 3
3x = 1 (False)
3* 3 ≠1
3x = 33 (False)
3 *3 ≠ 33
7x - 2 =19 (True)
7 *3 - 2 = 19
21 - 2 = 19
19 = 19
2x = 5 (False)
2 *3 ≠ 5
5x = 15 (True)
5 * 3 = 15
15 = 15
5x + 6 = 21 (True)
5 * 3 + 6 = 21
15 + 6 = 21
21 = 21

P: 15 Area: 8
Step-by-step explanation:
Use the line to split the shape. For P add all the numbers and add a 4 and a 1 too. For the area, you have to multiply 2 by 2 because of the cube, then mulitply 4 by 1 because 2+2=4 and the other number is one. REMEMBER TO SHOW YOUR WORK AND DOUBLE-CHECK!

Answer:
number 1 the outliers....................
Answer: B) The distribution is symmetric
Explanation:
The center of the distribution is the highest point. As you move to the left or right, the heights of each bar steadily decrease. Notice that the right hand side is a mirror copy of the left hand side. This mirroring is exactly what it means to be symmetric. If we had outliers, then we'd have bars that are further away from the main group, but we don't have such a thing happening here.
If the distribution was skewed left, or negatively skewed, then we'd have outliers that are smaller than the main group. On the other hand, if we had a skewed right (positively skewed) distribution, then we'd have outliers larger than the main group. We don't have any of these cases happening, so that's why the data isn't skewed in any way.

Question
An ant weighs 8.8x10 pound and can
carry objects up to 5,000 times greater than
its own body weight.
What is the greatest weight, in pounds, the
ant can carry?
Express your answer in standard form.
Answer: 880000
Step-by-step explanation: 8.8 x 10^ 5 = 880000
An ant can carry 0.044 pound of weight.
Important information:
Weight of an ant is 8.8x10⁻⁶ poundThey can carry objects up to 5,000 times greater than their own body weight.Standard form:Weight of an ant in standard form is:
[tex]8.8x10^{-6}=8.8\times \dfrac{1}{1000000}[/tex] pound
[tex]8.8x10^{-6}=0.0000088[/tex] pound
They can carry objects up to 5,000 times greater than their own body weight. So, the possible weight they can carry is:
[tex]0.0000088\times 5000=0.044[/tex]
Therefore, an ant can carry 0.044 pound of weight.

Step-by-step explanation:
here's your solution
==> k^2 - 5k + 4. [ is expression ]
==> by using middle term split
==> k^2 - 4k - k + 4
==> taking common from each
==> k(k - 4) - 1 (k - 4)
==> (k - 1) , (k - 4).
==> k - 1 = 0
==> k = 1
==> k - 4 = 0

write a rule for the sequence. then, find the unknown term 2.1, 4.3, 6.5, ..., 10.9
Answer
8.7
All the first digits are even numbers..and the numbers behind the decimal points are odd numbers
Answer:
8.7
Step-by-step explanation:
I'm assuming you want the term between 6.5 and 10.9
The sequence is aritmetic with a
common difference of 6.5 - 1.3 = 4.3 - 2.1 = 2.2
6.5 + 2.2 = 8.7
