Simple :)
Area of shaded part = are of 1/4 circle - area of both triangles.
Are of circle = pie r^2 so 100x3.14 = 314 cm2.
Area of triangle AOB= area of triangleDOE = bh/2= 5x10/2= 25 each
However, the traingles share a common area which is quad DOB(I)
Lets take traingle AOE, whose are is bh/2=10x10/2=50cm2.
50-area of triangle A(I)E= 50-(

If Julie invests $9,250 at a rate of 7%, compounded weekly, find the value of the investment after 5 years.
Reil [10]

Answer:

Option D is correct.

Step-by-step explanation

Principal =  $9250

rate of interest = 7%  or 0.07

time = 5 years or 260 weeks

      [ Since there are 52 weeks in a year . for 5 years it will be 5x52=260 weeks]

Applying the formula  

Amount after t years =       P(1+\frac{r}{n} )^{nt}

                                         where P = principal

                                                     r = rate % in decimals

                                                    n= number of times in a year

                                                     t = times ( in years)

                          plugging the values  in the formula

              Amount =  9250(1+\frac{0.07}{52} )^{(52X(5)}

                             =  9250(1+0.001346 )^{(260)}

                              = 9250(1.001346 )^{(260)}

                               = 9250(1.418733588)

                                =$13123.29

Jen thought of a rule, and made an in-out table for it. On the coordinate plane, Jen recorded her rule as points, but then she a
Kryger [21]

Answer:

y = (1/2)x + 3

Step-by-step explanation:

The points are separated by 1 vertical unit for each 2 horizontal units, so the slope of the line through them is ...

slope = vertical change / horizontal change = 1/2

There is a point on the y-axis at y=3 where x=0, so we know the y-intercept of the line is 3. Then, in slope-intercept form, the equation of the line can be written ...

y = slope · x + y-intercept

y = (1/2)x + 3

A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for t
hoa [83]

Answer:

Since p value <0.1 accept the claim that oven I repair costs are more

Step-by-step explanation:

The data given for two types of ovens are summarised below:

Group   Group One     Group Two  

Mean 85.7900 78.6700

SD 15.1300 17.8400

SEM 1.9533 2.3840

N 60       56      

Alpha = 10%

H_0: \mu_1 - \mu_2 =0\\H_a: \mu_1 - \mu_2> 0

(Right tailed test)

The mean of Group One minus Group Two equals 7.1200

df = 114

 standard error of difference = 3.065

 t = 2.3234

p value = 0.0219

If p value <0.10 reject null hypothesis

4) Since p value <0.1 accept the claim that oven I repair costs are more

Cylinder A has a volume of 360 cm3. Cylinder B has a base and height identical to that of cylinder B, but leans to the right in
Anuta_ua [19.1K]
I think the volume of cylinder B will be the same as that of cylinder A that is 360cm³
This is because the volume of the cylinder is dependent on the base and the perpendicular height, therefore, the slanting of the cylinder wont change its volume
