Find the measure of <8
Please help i need this to pass
Answer:
28
Step-by-step explanation:
a^2+b^2=c^2
a^2+96^2=100^2
a^2+9216=10000
a^2=784
a^2= √784
a=28
Answer:
28 in.Step-by-step explanation:
Let,
The unknown leg be = x
According to Pythagoras Theorem,
[tex] {hypotenuse}^{2} - {base}^{2} = {height}^{2} [/tex]
[tex] = > {100}^{2} - {96}^{2} = {x}^{2} [/tex]
[tex] = > {x}^{2} = 10000 - 9216[/tex]
[tex] = > {x}^{2} = 784[/tex]
[tex] = > x = \sqrt{784} [/tex]
=> x = 28
Hence,
the another leg is 28 in. (Ans)

A university researcher wants to estimate the mean number of novels that seniors read during their time in college. An exit survey was conducted with a random sample of 9 seniors. The sample mean was 7 novels with standard deviation 2.29 novels. Assuming that all conditions for conducting inference have been met, what is a 95 percent confidence interval for the population mean number of novels read by all seniors?
Answer:
(5.240 ; 8.760)
Step-by-step explanation:
Given :
Sample mean, xbar = 7
Standard deviation, s = 2.29
Sample size, n = 9
95% confidence interval for the population mean :
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/sqrt(n)
Tcritical at 0.05 ; df = 8 = 2.306
Margin of Error = 2.306 * 2.29/sqrt(9)
Margin of Error = 1.760
Lower boundary = (7 - 1.760) = 5.240
Upper boundary = (7 + 1.760) = 8.760
(5.240 ; 8.760)
Complete the table for the given rule.

Answer: 4= 2 8=3 12=4
Step-by-step explanation:
We see that 1/4 is the x, so we can multiply 4 by 1/4 which gives us 1 and then we add 1 because the equation has a +1. Now we do the same to the 8, 8(1/4 +1) =3.

6.A random sample of 60 married couples who have been married 7 years was ask the number of children they have. You may assume requirements are satisfied.The results of the survey are as follow000333132231324033310233142313350230442232222343221432421232a.What is the shape of the distribution of the sample mean? Why?b.Compute a 95% confidence interval for the mean number of children of all couples who have been married for 7 years. Interpret the interval.c.Computer the 99% confidence interval for the mean number of childrenof all couples who have been married 7 years. Interpret the interval.
Answer:
(1.962 ; 2.578) ;
There is a 95% chance that the true population mean of the number of children of all couples who have been married for 7 years lies within the interval (1.962 ; 2.578);
(1.865 ; 2.675);
There is a 99% chance that the true population mean of the number of children of all couples who have been married for 7 years lies within the interval (1.8646 ; 2.6754)
Step-by-step explanation:
Given the data :
0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 4, 5
Using calculator :
Mean, xbar = 2.27
Standard deviation, s = 1.219
Sample size = 60
Confidence interval :
Xbar ± Margin of error
Margin of Error = Zcritical * s/sqrt(n)
Zcritical at 95% = 1.96
Margin of Error = 1.96 * 1.219/ sqrt(60) = 0.3084
Lower boundary = (2.27 - 0.3084) = 1.962
Upper boundary = (2 27 + 0.3084) = 2.578
(1.962 ; 2.578)
There is a 95% chance that the true population mean of the number of children of all couples who have been married for 7 years lies within the interval (1.962 ; 2.578)
C.) 99% confidence interval :
Xbar ± Margin of error
Margin of Error = Zcritical * s/sqrt(n)
Zcritical at 99% = 2.576
Margin of Error = 2.576 * 1.219/ sqrt(60) = 0.4054
Lower boundary = (2.27 - 0.4054) = 1.8646
Upper boundary = (2.27 + 0.4054) = 2.6754
(1.865 ; 2.675)
There is a 99% chance that the true population mean of the number of children of all couples who have been married for 7 years lies within the interval (1.8646 ; 2.6754)
Which equation could represent the following:
5 less than a number is 8.
On - 5 = 8
0 5 - n = 8
On + 5 = 8

Step-by-step explanation:
5 less than a number = a number subtracted by 5
Write the equation of the line that passes through (−3, -5) and (-2, 10) in slope-intercept form
Answer:
y = 15x + 40
Step-by-step explanation:
(-3, -5) and (-2, 10)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(10 - (-5)) / (-2 - (-3))
Simplify the parentheses.
= (10 + 5) / (-2 + 3)
= 15 / 1
Simplify the fraction.
15/1
= 15
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 15x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-2, 10). Plug in the x and y values into the x and y of the standard equation.
10 = 15(-2) + b
To find b, multiply the slope and the input of x(-2)
10 = -30 + b
Now, add 30 to both sides to isolate b.
40 = b
Plug this into your standard equation.
y = 15x + 40
This is your equation.
Check this by plugging in the other point you have not checked yet (-3, -5).
y = 15x + 40
-5 = 15(-3) + 40
-5 = -45 + 40
-5 = -5
Your equation is correct.
Hope this helps!

2x^2 + 16x + 28 = 0?
Answer:
[tex]x=-4+\sqrt{2}[/tex]
[tex]x=-4-\sqrt{2}[/tex]
Step-by-step explanation:
The quadratic formula is an equation that can be used to find the roots of a quadratic equation when one is given the equation in standard form. A quadratic equation in standard form is the following,
[tex]ax^2 +bx + c=0[/tex]
The quadratic formula is the following,
[tex]\frac{(-a)(+-)\sqrt{(x)^2-4(b)(c)}}{2(a)}[/tex]
Substitute in the given coefficients for the following equation,
[tex]2x^2 + 16x + 28 = 0[/tex]
Substitute,
[tex]\frac{-16(+-)\sqrt{(16)^2-4(2)(8)}}{2(2)}[/tex]
Simplify,
[tex]\frac{-16(+-)\sqrt{256-224}}{4}\\\\=\frac{-16(+-)\sqrt{32}}{4}\\\\=\frac{-16(+-)4\sqrt{2}}{4}\\\\=-4(+-)\sqrt{2}[/tex]
The roots of the quadratic equation ([tex]2x^2+16x+28=0[/tex]) are ([tex]x=-4+\sqrt2[/tex]) and ([tex]x=-4-\sqrt{2}[/tex])

3. Find the slope of the line through the pair of points.
(12, 2), (-7,5)
Answer:
-3/19
Step-by-step explanation:
Given data
We have the coordinates
(12, 2), (-7,5)
x1=12
y1=2
x2=-7
y2=5
The expression for the slope is given as
Slope= y2-y1/x2-x1
Substiute
Slope= 5-2/-7-12
Slope= 3/-19
Hence the slope is -3/19
What is the range of the function graphed below?
Answer:
-3<y<=3 or B
Step-by-step explanation:
first we find the smallest y value which is -3
then we find the largest y vlaue which is three
so since there is an open circle at negative three we do not include it while at three we do.
so the answer would be -3<x<=3
