Answer:
a = 0
b = [tex]\frac{\pi }{4}[/tex]
c = 0
d = 3
e = 5
f = [tex]\sqrt{34-r^2}[/tex]
Step-by-step explanation:
Equation of the solid sphere = x^2 + y^2 + z^2 ≤ 34 ------- (1)
at Z = 5
since the bottom of the sphere(z) is flat = 5 we will use cylindrical coordinates
concentrating in the first octant as mentioned in the question
at Z = 5 , equation 1 becomes :
x^2 + y^2 + 25 ≤ 34 = x^2 + y^2 = 9
hence the radius around the xy axis = [tex]\sqrt{9}[/tex] = 3
that means the radius is : 0 ≤ r ≤ 4 , 0 ≤ ∅ ≤ [tex]\frac{\pi }{4}[/tex]
next we have to find the upper bound of: Z = ±[tex]\sqrt{34-r^2}[/tex] we will pick out only the positive
5 ≤ z ≤ [tex]\sqrt{34 - r^2}[/tex]
therefore for the Volume = ∫ba∫dc∫fe
a = 0
b = [tex]\frac{\pi }{4}[/tex]
c = 0
d = 3
e = 5
f = [tex]\sqrt{34-r^2}[/tex]

What x values would be good to use so she does not get fractions for her y values when making the table of ordered pairs.
Answer:
-3, 0, 3
Step-by-step explanation:
Given, [tex] y = -\frac{4}{3}x + 2 [/tex], the set of x values that will make Kayda not to get y values that are not fraction are -3, 0, 3.
This is so, because,
when x = -3, [tex] y = -\frac{4}{3}(-3) + 2 = \frac{12}{3} + 2 = 4 + 2 = 6 [/tex]
when x = 0, [tex] y = -\frac{4}{3}(0) + 2 = -0 + 2 = 2 [/tex]
when x = 3, [tex] y = -\frac{4}{3}(3) + 2 = \frac{-12}{3} + 2 = -4 + 2 = -2 [/tex]
The correct response is -3, 0, 3

Find the least common multiple of 5 and 2.
That would be 10.
That means we have to multiply the first fraction by 2/2 and the second one by 5/5
-3/5*2/2
Multiply the numerators together and the denominators together.
-6/10
Repeat with the second fraction.
-8/2*5/5
-40/10
Our new expression is
-6/10+-40/10
-46/10
Simplify
-23/5
As a mixed number that would be:

How many inches are in 14 feet, 8 inches? Enter only the number. Do not include units
Answer:
176
Step-by-step explanation:
14x12 = 168 + 8 = 176
There are 176 inches in 14 feet, 8 inches.
To find the total number of inches in 14 feet, 8 inches, we need to convert the feet to inches and then add the inches.
So, 14 feet = 14 x 12
= 168 inches.
Adding the extra 8 inches, the total is:
= 168 inches + 8 inches
= 176 inches.
Therefore, there are 176 inches in 14 feet, 8 inches.

One megabyte of cell phone storage space is 2^{20} bytes. An app uses 4^4 megabytes of storage space. How many bytes of storage space does the app use? Write your answer as a power of 2.
Answer:
2²⁰ bytes
Step-by-step explanation:
Given
[tex]Phone\ Storage = 2^{20}\ bytes[/tex]
[tex]App\ Storage = 4^4\ megabytes[/tex] of phone storage space
Required
Determine the storage space of the app in bytes
To answer this, we simply multiply the app storage by the phone storage
This gives:
[tex]Total = 2^{20} * 4 ^4[/tex]
Express 4 as 2²
[tex]Total = 2^{20} * 2^2^* ^4[/tex]
[tex]Total = 2^{20} * 2^8[/tex]
Apply Laws of Indices
[tex]Total = 2^{20+8}[/tex]
[tex]Total = 2^{28}[/tex]
Hence, the storage space of the app is 2²⁰ bytes
The data below are the temperatures on randomly chosen days during the summer and the number of employee absences at a local company on those days. Construct a 95% prediction interval for y, the number of days absent,
given x = 95 degrees and y= 0.449x - 30.27
Temperature, x 72 85 91 90 88 98 75 100 80
Number of absences, y 3 7 10 10 8 15 4 15 5
Answer:
12.385; (10.0, 14.7)
Step-by-step explanation:
Given the following information :
Temperature, x 72 85 91 90 88 98 75 100 80
Number of absences, y 3 7 10 10 8 15 4 15 5
The obtained regression equation:
y= 0.449x - 30.27
Where y = predicted variable ; x = independent variable ; - 30.27 = intercept and slope = 0.449
Constructing a 95% prediction interval for y:
x = 95°
Inputting x = 95 into the regression equation :
y= 0.449(95) - 30.27
y = 42.655−30.27 = 12.385
Prediction interval = y ± error margin
To save computing time, error margin (E) can be obtained using the online error margin calculator.
Obtained error margin (E) value = 2.3398
(12.385 - 2.3398, 12.385 + 2.3398)
(10.0452, 14.7248)

write the equation of a line in any form that is parallel 2y = 4x + 8 through the point of (1,3) plz and thank you
Answer:
y = 2x+1
Step-by-step explanation:
[tex]2y =4x+8\\\\ Write \:in \: y =mx+b \:form\\\\\frac{2y}{2} = \frac{4x}{2} +\frac{8}{2} \\\\y =2x +4\\m =2\\(1,3) =(x_1,y_1)\\Substitute\:values\:into\:point-slope\:form\\\\y-y_1=m(x-x_1)\\y-3=2(x-1)\\y-3 = 2x-2\\y=2x-2+3\\y =2x+1[/tex]
Step-by-step explanation:
Hey, there!!
Here, the given point is (1,3).
Now, Using one point formula we need to find the equation of the line passing through point (1,3).
Now,
[tex](y - y1) = m1(x - x1)[/tex]
Keeping values,
[tex](y - 3) = m1(x - 1)[/tex]
It is the 1st equation.
Similary, you have another equation,
2y = 4x + 8..............2nd equation.
or, 4x - 2y +8 =0
M2 from equation 2,
[tex] = \frac{ - coeff. \: of \: x}{coeff. \: of \: y} [/tex]
[tex] = \frac{ - 4}{ - 2} [/tex]
Therefore, m2 = 2
Now,
As per the condition of parallel lines,
m1 = m2 = 2
Now, substituting the value of m1 in equation 1st.
(y-3) = 2 (x-1)
y-3 = 2x - 2
or, 2x-y+1 = 0 ......is the required equation.
Hope it helps...
This histogram shows the percentage of the population that smokes tobacco for 123 countries. Which one of the following values is the most reasonable estimate for the IQR?
Answer:
9.5
Step-by-step explanation:
The formula for interquartile range = Third Quartile - 1st Quartile
= Q3 - Q1
Looking at the histogram given, the class width = 6
Step 1
We find the number of values = n
n = 1 + 12 + 26 + 27 + 31 + 19 + 6 + 1
= 123
Frequency Cumulative Frequency
1 1
12 13
26 39
27 66
31 97
19 116
6 122
1 123
Step 2
We find Q1 ( First Quartile)
Q1 =1/4 (n + 1) value
Q1 = 1/4(124) value
= 31st value
The first Quartile = 31st value
31 - 13 = 18
31st value = 12 + (18/26 × class width)
= 12 +( 18/26 × 6)
First Quartile = 16.153846154
Third Quartile =Q3 =3/4 (n + 1) value
Q1 = 3/4(124) value
= 93rd value
The first Quartile = 93rd value
93 - 66 = 27
93rd value = 1 + (27/97 × class width)
=24 +( 27/97 × 6)
Third Quartile= 25.670103093
Interquartile range = Q3 - Q1
= 25.670103093 - 16.153846154
= 9.5162569392
Approximately = 9.5
Inter Quartile range = 9.5
