The population standard deviation for the heights of dogs, in inches, in a city is 7.5 inches. If we want to be 90% confident that the sample mean is within 2 inches of the true population mean, what is the minimum sample size that can be taken
Answer: 39
Step-by-step explanation:
Formula of sample size :
[tex]n=(\dfrac{z^c\times\sigma}{E})^2[/tex] , where [tex]z^c[/tex] = critical z-value for confidence level , [tex]\sigma[/tex] = population standard deviation , E = margin of error.
[tex]\Rightarrow\ n=(\dfrac{1.645\times7.5}{2})^2\\\\\Rightarrow\ n=(6.16875)^2=38.05347\approx39[/tex]
Hence, the minimum sample size that can be taken = 39

6. The graph below displays the growth of a plant, in millimeters.
Growth of Plant
in one week, the plant grows 125 mm so the slope of the line is 12
The plant grows 125 mm each week so the slope of the line is 125.
The slope is one because the plant grows one mm each week.

Based on the given graph, explain the slope of the line in terms of the unit rate of the
plant's growth, in millimeters, per week.
Answer:
Step-by-step explanation:
B
From the graph the slope of a line is 100.
Given that, the graph below displays the growth of a plant, in millimeters.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1).
From the given graph, the slope is rise/run
= 400/4
= 100
Therefore, from the graph the slope of a line is 100.

Put the following equation of a line into slope-intercept form
2x - 2y = 6
Answer:
Y=-2x+3
Step-by-step explanation:
2x-2y=6
2y=-2×+6
y=-2×+6/2
y=-2x+3
The equation of a line into slope-intercept form is y = x - 3
The standard form of an equation in slope-intercept form is expressed using the equation y = mx + b
m is the slope of the line
b is the y-intecept
Given the equation 2x - 2y = 6
Divide through by 2
x - y = 3
-y = -x + 3
Multiply through by -1
-(-y) = -(-x) + (-3)
y = x - 3
Hence the equation of a line into slope-intercept form is y = x - 3

How to Solve X-3/8= 7/16
Answer:
x=13/16
Step-by-step explanation:
The question is asking us to isolate the variable x. This means that we need to add -3/8 to both sides of the equation. Because the denominators of the fractions 3/8 and 7/16 are not the same, we need to find a common denominator, which is 16. (So we change 3/8 to 6/16 because the two fractions are equal). Now that we have the fractions 6/16 and 7/16 we can add the two to get x=13/16

You may asssume there is no tax. equation editorEquation Editor help (equations) (b) Solve your equation above for the number of ice cream cones nn.
Answer:

Step-by-step explanation:
10.50÷ 1.50≡n
10.50÷1.50≡7
7×1.50≡10.50
The equation is 10.50 ÷ 1.50 = n, and n = 7.
What is division?One of the four fundamental operations in mathematics is division; the other three are addition, subtraction, and multiplication. Simply put, division is the process of dividing a large group into smaller ones so that each group has the same number of items. It is an activity utilized for equivalent gathering and equivalent partaking in math.
Given total spend on ice cream = $10.50
cost of 1 ice cream = $1.50
let n be the total number of ice cream,
n = 10.50 ÷ 1.50
n = 10.50/1.50
n = 7
Hence the equation is n = 10.50 ÷ 1.50 and n = 7.

Answer:
a. His flag ended up with base angles of 86° and 62°. so the stick was 12° out of alignment from the correct position (both angles
74°).
Step-by-step explanation:
First, let's calculate the measures of the base of the angles Neko ended up with.
The measure of the angle adjacent to the exterior angle = 180° - 118° = 62°
The measure of the other base = 180° - (62° + 32°) = 180° - 94° = 86°
So, Neko ended up with 86° and 62°.
To make a flag that is in the form of an isosceles ∆, it means the measure of the two bases most be equal to each other.
Since he measures the tip of the flag to be 32°, the measure of the remaining two equal bases ought to be (180 - 32)/2 = 148/2 = 74° each.
The difference between 74° and what he ended up with = 86 - 74 = 12°.
74 - 62 = 12°.
Therefore, the stick was 12° out of alignment.
The right option is a.

given cosx = 60/61, find sin2x
Recall that for all x,
cos²(x) + sin²(x) = 1
So we have
sin(x) = ± √(1 - (60/61)²) = ± 11/61
Recall the double angle identity,
sin(2x) = 2 sin(x) cos(x)
From here, we get
sin(2x) = 2 (± 11/61) (60/61) = ± 1320/3721
In case you meant to ask about sin²(x), we get
sin²(x) = 1 - cos²(x) = 121/3721
