Based on the z-statistic of –2.5 for the sample data, should the null hypothesis be rejected? Yes, because the z-statistic lies within the critical region. Yes, because the z-statistic lies outside of the critical region. No, because the z-statistic lies within the critical region. No, because the z-statistic lies outside of the critical region.
Answers
Answer:
No, because z-statistics lies within the critical region.
Step-by-step explanation:
The z value is calculated to determine whether the null hypothesis should be accepted or rejected. The null hypothesis is rejected when the z-value lies outside the critical region. The critical region is determined by the sample data.
Answer:
A) Yes, because the z-statistic lies within the critical region.
Step-by-step explanation:
Next one is B) The claim should be rejected.

A triangle has a perimeter of 13x-21 units. One side is 4x+3 units. The other side is 5x-8 units. Write an expression to find the missing side.
Answers
Answer:
4x - 16
Step-by-step explanation:
A triangle is a three sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
the perimeter of a triangle = sum of the side lengths
let the unknown length be represented with y
13x - 21 = 4x + 3 + 5x - 8 + y
13x- 21 = 9x - 5 + y
Make y the subject of the formula
13x - 21 - 9x + 5 = y
4x - 16 = y
the side length = 4x - 16

We always follow these rules when we are Multiplying and Dividing numbers with Scientific Notation.
1. If the numbers are not in scientific notation, convert them.
2. Regroup the numbers using the commutative and associative properties of exponents.
3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.
-Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾ to multiply the bases.
4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.
5. Join the new coefficient to the new power of 10 to get the answer.
--------------------------------------------------------------------------------------------------------------
Let's start!
Our equation:
(5.2 × 10⁶)(7 × 10⁸)
--------------------------------------------------------------------------------------------------------------
1. If the numbers are not in scientific notation, convert them.
They are in scientific notation, so we go on to step 2.
2. Regroup the numbers using the commutative and associative properties of exponents.
(5.2 × 7)(10⁶ × 10⁸)
3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.
-Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾ to multiply the bases.
5.2 × 7 = 36.4
10⁶ × 10⁸= 10⁽⁶⁺⁸⁾ = 10¹⁴
4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.
36.4 = 3.64 × 10¹
5. Join the new coefficient to the new power of 10 to get the answer.
3.64 × 10¹ × 10¹⁴
3.64 × 10⁽¹⁺¹⁴⁾ = 3.64 × 10¹⁵
==================================================================
3.64 × 10¹⁵

What is the equation of the line that goes through the points (4,-1) and
(2,3)?
Answers
Answer:
y = -2x + 7
Explanation:
y = mx + b
m = slope
b = y-intercept
y = a given y coordinate
x = a corresponding x coordinate
First, we need to find the slope (m).
1) (4, -1)
2) (2/3)
m = slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{3-(-1)}{2-4}[/tex] = [tex]\frac{4}{-2}[/tex] = -2
plug in the values to the equation y = mx + b
-1 = -2(4) + b
-1 = -8 + b
7 = b
now, we can substitute in m and b into the equation y = mx + b
y = -2x + 7
