Answer:
There is sufficient evidence at the 0.05 level
Null hypothesis ; H0 : p = 0.47
Alternative hypothesis : H1 : p ≠ 0.47
Step-by-step explanation:
percentage favoring construction of adjoining community = 47%
level = 0.05
To determine if the 0.05 confidence level is enough to support the major's claim we have to state the Null and alternative hypothesis
Null hypothesis ; H0 : p = 0.47
Alternative hypothesis : H1 : p ≠ 0.47
A cylinder has a radius of 7 inches and a height of 20 inches. Which is closest to the surface area of this cylinder?
517 sq in.
769 sq in.
1,187 sq in.
3,077 sq in.
Answer:
1,187 (It is the closest)
Step-by-step explanation:
Formula: 2πrh+2πrr
Equation: 2x3.147x20 + 2x3.14x7x7
Solution:879.2 + 307.72=1,186.92
The surface area of the cylinder with a radius of 7 inches and a height of 20 inches is closest to 1,187 square inches.
What is a Cylinder?A cylinder is a three dimensional geometric figure on which there are two identical circular bases which are parallel to each other located within a distance. This distance is called the height of the cylinder and the radius is the radius of this circle.
Axis of cylinder is the line segment connecting the center of two circular bases.
Here, we have to find the surface area of the cylinder.
Height of the cylinder = 20 inches
Radius of the cylinder = 7 inches
Surface Area of the cylinder = 2πr (h + r), where h is the height of the cylinder and r is the radius of the cylinder.
Surface Area = 2π × 7 (20 + 7)
= 2π × 7 × 27
= 2π × 189
= 378π
= 378 × 3.14
= 1186.92 ≈ 1187
Hence the surface area of this cylinder is closest to 1187 square inches.

Docs cookie recipe calls for 3 cups of sugar and 2 cups of flour. how many cups of sugar needed for 14 cups of flour?
Answer:
21 cups of sugar
Step-by-step explanation:
so it gives you the ratio for cups of sugar(or as i'm going to use it, COS) and cups of flower(COF), which is 3:2, so if you have 14 cups of flower, you would divide 14 by the COF part of the ratio, which is 2, which gives you 7, then you would multiply the COS part of the ratio, which is 3, by 7 to get the number of cups of sugar needed for 14 cups of flower.

A graduated cylinder (a cup) actually contains 7.5 milliliters of water, When Han measures the volume of the water inside the graduated cylinder, his measurement is 7 milliliters. Which of these is the closest to the percent error for Han’s Measurement
107.1%
93.3%
7.1%
6.7%
Given:
Actual volume of graduated cylinder (a cup) = 7.5 milliliters.
Han measures the volume of graduated cylinder = 7 milliliters.
To find:
The percent error for Han’s measurement.
Solution:
We have,
Actual volume = 7.5 milliliters
Incorrect volume = 7 milliliters
So, the error in the measurement of volume is
[tex]Error=7.5-7=0.5[/tex]
Now,
[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=\dfrac{\text{Error}}{\text{Actual value}}\times 100[/tex]
[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=\dfrac{\text{Error}}{\text{Actual value}}\times 100[/tex]
[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=\dfrac{0.5}{7.5}\times 100[/tex]
[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=\dfrac{50}{7.5}[/tex]
[tex]%\text{Error}=\dfrac{text{Error}}{\text{Actual value}}\times 100[/tex][tex]\text{Percent error}=6.6666667[/tex]
[tex]\text{Percent error}\approx 6.7\%[/tex]
The percent error for Han’s measurement is 6.7%.
Therefore, the correct option is D.

Answer:
19/28
Step-by-step explanation:
The value of the expression ( 3 / 7 ) + ( 1 / 4 ) will be ( 19 / 28 ).
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression ( 3 / 7 ) + ( 1 / 4 ) will be solved as below:-
( 3 / 7 ) + ( 1 / 4 ) = ( 12 + 7 ) / 28
( 3 / 7 ) + ( 1 / 4 ) = ( 19 ) / 28
Therefore, the value of the expression ( 3 / 7 ) + ( 1 / 4 ) will be ( 19 / 28 ).

If r + 9 is 4 more than s, then r-11 is how
much less than s?
A) 9
B) 11
C) 16
D) 20
Answer:
16
Step-by-step explanation:
Given that :
r + 9 = 4 greater Than s
r - 1 1 is how much less than s
r + 9 = s + 4
Solve for r
Subtract 9 from both sides
r + 9 - 9 = s + 4 - 9
r = s - 5
Hence,
r - 11 = (s - 5) - 11
r - 11 = s - 5 - 11
r - 11 = s - 16
r - 11 = s - 16
Therefore, r - 11 is 16 less than s
