Can someone please answer this question for me with explanation bc im kinda having a hard time
Answer:
Step-by-step explanation:
First we find out the area of circle, and then subtract the area of triangle from it to find the area of the shaded region
Area of Circle
Here, r=radius
area of circle= π×r²
= π × 5² (radius=half of diameter)
= 25π
= 78.54cm²
Area of Triangle
Here, b=base, h=height
area of triangle = [tex]\frac{1}{2\\}[/tex]×b×h
= [tex]\frac{1}{2}[/tex]×8×6
= 24cm²
Area of shaded region= area of circle - area of triangle
= 78.54 - 24
= 54.54
≈ 54.5cm² [Ans]

The owner of a football team claims that the average attendance at games is over 74,900, and he is therefore justified in moving the team to a city with a larger stadium. An independent investigator will conduct a hypothesis test to determine whether his claim is accurate. This test is ________. Group of answer choices Two-sided Lower-tailed Upper-tailed
Answer:
Option c (Upper tailed) is the correct choice.
Step-by-step explanation:
Given that:
The average attendance is:
= 74,900
We will have to test:
⇒ [tex]H_0:\mu \leq \mu_0[/tex]
or,
[tex]H_0: \mu \leq 74,900[/tex]
Verses,
⇒ [tex]H_1: \mu> \mu_0[/tex]
or,
[tex]H_1: \mu >74,900[/tex]
The other given alternatives aren't connected to the given scenario. So the above is the correct one.

64 is what percent of 80
Answer:
80%
Step-by-step explanation:
x : 100 = 64 : 80
x = (100 * 64)/80 = 80%
Answer:
80%
Step-by-step explanation:
Is means equals and of means multiply
64 = P * 80
Divide each side by 80
64/80 = P
.8 = P
Change to percent form by multiplying by 100
80% = P

what pairs of degree measures NOT belong to the
group?
Answer:
B. 56° and 38°
Step-by-step explanation:
The sum of each of the two angles sums up to 90° ;
A.) 13° and 77°
Sum of A ; (13 + 77)° = 90°
B.) 56° + 38°
Sum = 56° + 38° = 94°
C) 37° and 53°
Sum = 37° + 53° = 90°
D.) 42° and 48°
Sum = 42° + 48° = 90°
Hence, the pair of degree measure which does not belong is B. 56° and 38°

A cylinder has a height of 12 inches and a radius of 1.5 inches. What is its voulme? Round your answer to the nearest tenth. Use 3.14 for
π
.
Find the area of the top, which is a circle.
Area of a circle = pi x r^2
Area = 3.14 x 1.5^2 = 7.065
Now for the volume multiply the area of the top by the height:
7.065 x 12 = 84.78 cubic inches
Round to the nearest tenth: 84.8 cubic inches
Answer:
Volume of cylinder is 84.78 inches.
Step-by-step explanation:
Volume of cylinder = π × r ² × h
Where,
r , is the Radius of cylinder. h ,is the height of cylinder.And we have given that
Height of cylinder , h = 12 inchesRadius of the height , r = 1.5 inchesValue of π = 3.14Substitute the values
Volume of cylinder = 3.14 × (1.5 inches) × 12 inches
= 3.14 × 2.25 inches² × 12 inches
multiply the values , we get
Volume of cylinder = 84.78 inches³.
84.8 inches³ is the round nearest to tenth.
Choose the pair of sets which is equivalent.

just try out some values to get a clue
f(0)<= -|0+1|+1 = 0
okay, that value is true for all graphs
let's try another
f(1) <= -|1+1|+1 = -1
for x=1 the inequality only applies for a region less or equal to -1
B and D are clearly out. C covers just to much above
Only A remains as an option

Recall the equation for a circle with center (h, k) and radius r. At what point in the first quadrant does the line with equation y = 0.5x + 5 intersect the circle with radius 3 and center (0,5)?
X =
y =
Answer:
The point of intersection is:
[tex]\displaystyle \left(\frac{6\sqrt{5}}{5}, \frac{3\sqrt{5}}{5}+5\right)\approx \left(2.68, 6.34)[/tex]
Step-by-step explanation:
We want to find the point in QI at which the line with the equation:
[tex]y=0.5x+5[/tex]
Intersect a circle with a radius of 3 and a center of (0, 5).
First, write the equation of a circle. The equation for a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
Since our center is (0, 5), h = 0 and k = 5. The radius is 3. So, r = 3. Substitute:
[tex](x-0)^2+(y-5)^2=(3)^2[/tex]
Simplify:
[tex]x^2+(y-5)^2=9[/tex]
At the point where the two equations intersect, its x-coordinate and y-coordinate will be the same. Therefore, we can substitute the equation of the line into the equation of the circle and solve for x. So:
[tex]x^2+((0.5x+5)-5)^2=9[/tex]
Simplify:
[tex]x^2+(0.5x)^2=9[/tex]
Square:
[tex]x^2+0.25x^2=9[/tex]
Combine like terms:
[tex]\displaystyle 1.25x^2=\frac{5}{4}x^2=9[/tex]
Solve for x:
[tex]\displaystyle \begin{aligned} x^2&=\frac{36}{5} \\ x&=\pm\sqrt{\frac{36}{5}} \\ x&\Rightarrow \frac{6}{\sqrt{5}}=\frac{6\sqrt{5}}{5}\approx2.68\end{aligned}[/tex]
Note that since we are looking for the point of intersection in QI, x should be positive. So, we can ignore the negative answer.
To find the y-coordinate, substitute the x-value back into either equation. Using the linear equation:
[tex]\displaystyle y=0.5\left(\frac{6\sqrt{5}}{5}\right)+5=\frac{3\sqrt{5}}{5}+5\approx 6.34[/tex]
So, the point of intersection in QI is:
[tex]\displaystyle \left(\frac{6\sqrt{5}}{5}, \frac{3\sqrt{5}}{5}+5\right)\approx \left(2.68, 6.34)[/tex]

What is the decimal multiplier to increase by 4.3%?
Answer:
1.043
Step-by-step explanation:
Decimal multiplier to increase by x% is computed as:-
100% + x%
The decimal multiplier to increase by 4.3% would be
100% +4.3% = 104.3%
To remove% we divide the number by 100, so the number will become
Hence, The decimal multiplier to increase by 4.3% = 1.043

Which choice shows (40+10)+30 correctly rewritten using the associative property and then correctly simplified?
40 + (10 + 30) = 40 + 40 = 80
40 + 30 + 10 = 70 + 10 = 80
40 + (10 +30) = 50 + 30 =80
(10 +40) + 30 = 50 + 30 =80
Find the Area of the Shaded Region.
Round to the nearest tenth if necessary.
14 cm
25 cm
11 cm
Answer:
[tex]Shaded = 212.5cm^2[/tex]
Step-by-step explanation:
Given
See attachment
Required
The shaded region
First, calculate the area of the complete rectangle
[tex]Area =Length * Width[/tex]
[tex]Area = 14cm * 25cm[/tex]
[tex]Area = 350cm^2[/tex]
Next, calculate the area of the triangle
[tex]Area = \frac{1}{2} * Base * Height[/tex]
[tex]Area = \frac{1}{2} *25cm * 11cm[/tex]
[tex]Area = 137.5cm^2[/tex]
Subtract the area to calculate the shaded region area
[tex]Shaded = 350cm^2 - 137.5cm^2[/tex]
[tex]Shaded = 212.5cm^2[/tex]

9514 1404 393
Answer:
5196 m
Step-by-step explanation:
The difference in elevation is found by subtracting one elevation from the other. Usually, we're interested in the positive difference, so we subtract the smaller number from the larger.
5040 -(-156) = 5040 +156 = 5196
The difference in elevation is 5196 meters.

A researcher studying a memory enhancing technique had participants memorize nonsense words and definitions. Out of a list of 10 words, 57 participants were able to quickly learn 6.24 words on average with a standard deviation of 1.24. If it is known the mean number of words memorized in general is 5.65, is there sufficient evidence at that the memory enhancing technique helped participants learn more words?
a. What are the null and alternative hypotheses?
b. What is the value of the test statistic?
c. What is the critical value?
d. What is the decision?
e. What is the conclusion?
Answer:
A.
Null:
H0: u= 5.65
Alternative:
H1: u > 5.65
B.
The test statistic
Xbar = 6.24
u = 5.65
S = 1.24
N = 57
T = 6.24-5.65/(1.24/√57)
= 0.59/(1.24/7.5498)
= 0.59/0.1642
Test statistic = 3.593
C.
With alpha = 0.05
Df = n-1 = 57-1 = 56
T critical = 1.673
D.
If t test > 1.673 reject the null hypothesis
3.593>1.673, reject the null hypothesis
We conclude that there is enough evidence that the technique helped the participants to learn more.
