The lengths of the sides of a triangle are as follows:

base(b) = 2R and height(h) = R

With one of the triangle's vertices in the circle's centre and the other two on the circumference, we must determine the lengths of the sides of the triangle with the largest possible area that can be drawn within.

Let,

b = base of triangle

h = height of triangle

R = Radius of circle

Area of triangle = bh/2

The area of a triangle is bh/2, but since b/2 is shared by a triangle, the maximum area is constrained by the height h.

This would be the perpendicular height to the base, which is the radius R

The base is two radii b=2R and height is h= R

We start with lowest one i.e 1 × 1

Let’s consider any one face out of six faces of cube ,

as one face of grid or cube is made up of 25 small squares.

If we are facing difficulty in visualising then

simply we draw a 5× 5 board on paper, just as seen in above picture :

By using R1, R2 and all columns we shall be able to draw 4 such blocks.

Again, R2,R3 and R3, R4 and R4,R5 we can easily draw 4 squares each cash .

Thus, total square count of 2× 2 squares will be

= 16

similarly, we do it for 3× 3 and 4×4 and we will get 9 & 4 respectively.

For final one 5× 5 there is one big square

So, total squares for one face will be

Answer:

y = 136 degrees

Step-by-step explanation:

We can see that both x and y lie on a straight line. Their two angles add up to be a straight line....

We already know the value of x (44)

x + y = 180 degrees

44 + y = 180

(Subtract from both sides)

y = 136

So, y is 136 degrees

This looks correct, since angle y seems to be an obtuse angle

Step-by-step explanation:

ans is in the attachment.

A 95% confidence interval for population proportion p is (0.5336, 0.7213).

Given,

One difficulty in measuring the nesting success of birds is that the researchers must count the number of eggs in the nest, which is disturbing to the parents. Even though the researcher does not harm the birds, the flight of the bird might alert predators to the presence of a nest. To see if researcher activity might degrade nesting success, the nest survival of 102 nests that had their eggs counted, was recorded. Sixty-four of the nests failed (i.e. the parent abandoned the nest.)

To find,

Assuming that it is reasonable to regard the 102 nests in the sample as representative of the population of nests for which the eggs have been counted, construct and interpret a 95% confidence interval for the proportion of nests that have eggs counted that are then abandoned;

n = 102

x = 64

Point estimate = sample proportion = [tex]\hat p[/tex] = x / n = 64/102 =0.627

1 - [tex]\hat p[/tex] = 1 - 0.627 = 0.373

[tex]Z\alpha/2[/tex] = 1.96

The margin of error = E

                         [tex]= Z\alpha / 2 * \sqrt((\hat p * (1 - \hat p)) / n) = 1.96 * (\sqrt(0.627*(0.373) /102 ) = 0.0934[/tex]

A 95% confidence interval for population proportion p is;

[tex]\hat p[/tex]  - E < p <  [tex]\hat p[/tex]  + E

0.627 - 0.0934 < p < 0.627 + 0.0934

0.5336 < p < 0.7213

(0.5336, 0.7213)

Hence, a 95% confidence interval for population proportion p is (0.5336, 0.7213).

Using the Real rate of return,

the real value of the invetment at the end of one year is $1058.

Real rate of return:

The real rate of return is the present value of the return on investment after taxes and inflation.

By considering the expected inflation rate and the effective interest rate in the compounding interval, we can derive the real interest rate.

Real Rate Of Return Formula,

Real rate of return = [( 1+ Nominal rate )/(1+ inflation rate) ] - 1

The principal amount of investment by Mr.X ( A)

= $1,000

The nominal or current rate of interest (i)= 10%

The rate of inflation ( π )= 4%

pulging all the values in above formula we get,

rate of return (R) =[ ( 1 + i ) /(1+π)] - 1

=> R =[ (1+0.1 )/(1+0.04) ] - 1 = (1.1 / 1.04 ) - 1

=> R = 0.05769(approx.)

=5.8%(approx.)

so, real rate of return = 5.8%

Real value of investment after a year = principle amount (A) + { real rate return × principle amount}

Real value of investment =$1,000+{5.8%×$1,000}

=$1,000+$58

=$1,058

Hence, real value of investment at the end of year is $1,058.

Answer: 3 negative residuals and 5 positive residuals

Step-by-step explanation:  When the observed number is lower than the predicted number then this is an example of a negative residual. The tricky thing is this doesn't make much sense you would think that this would be a positive residual but it's not to that's something you need to remember!

example

observed number: 10

predicted number: 10.5

this is a negative residual and it's the opposite for the positive residual

The data set has 2 negative residuals and 6 positive residuals. which is the correct answer would be an option (A).

A residual is a difference between the observed value and the predicted value for a given data point. The sign of the residual indicates whether the predicted value is above or below the observed value.

The table defines the observed data values and the corresponding predicted values, based on a regression line of fit.

Observed    Predicted

9                    7.77

12                    12.87

12                    11.17

15                    14.57

17                    16.27

24                    24.77

28                    26.47

33                    31.57

In this case, the residuals for the data points would be calculated as follows:

Observed value - Predicted value = Residual

9 - 7.77 = 1.23 (positive)

12 - 12.87 = -0.87 (negative)

12 - 11.17 = 0.83 (positive)

15 - 14.57 = 0.43 (positive)

17 - 16.27 = 0.73 (positive)

24 - 24.77 = -0.77 (negative)

28 - 26.47 = 1.53 (positive)

33 - 31.57 = 1.43 (positive)

Based on these calculations, there are 2 negative residuals (-0.87 and -0.77) and 6 positive residuals (1.23, 0.83, 0.43, 0.73, 1.53, and 1.43).

Therefore, the data set have 2 negative residuals and 6 positive residuals.

Answer:

part a: AB = 12cm

part b: AB = 18cm

Step-by-step explanation:

sin(angle)=OPP/HYP

sine of an angle is a ratio of two sides of a right triangle. For sine, the ratio is the opposite side over the hypotenuse. In part a the marked angle is 30° and AB is the opposite side. The hypotenuse is given, 24cm.

So the sin 30°

= opp/hyp

= AB / 24

also given is the fact that sin30°=.5

Substitute that into our equation also.

sin30° = AB/24

.5 = AB/24

multiply both sides by 24.

.5×24 = AB

12 = AB

AB is 12 cm.

Part b is an identical calculation except the hypotenuse is 36cm.

sin30° = AB/36

In statistical hypothesis testing, the alternative hypothesis is one of the suggested propositions in the hypothesis test. In general, the purpose of a hypothesis test is to demonstrate that, under the given conditions, there is sufficient evidence to support the believability of an alternate hypothesis rather than the test's exclusive statement (null hypothesis). Because it is based on a review of the literature and previous studies, it is usually congruent with the research hypothesis. However, the research hypothesis is sometimes congruent with the null hypothesis.

In statistics, alternative hypotheses are frequently denoted as Hₐ or H₁. In a statistical hypothesis test, hypotheses are developed to be compared.

In the field of inferential statistics, two competing hypotheses can be compared using explanatory and predictive power.

500 jellybeans were originally present in the jar when 80 percent of the jellybeans in a jar were consumed by students in a classroom. Only 100 jelly beans are still available.

Given that,

80 percent of the jellybeans in a jar were consumed by students in a classroom. Only 100 jelly beans are still available.

We have to find how many jellybeans were originally present in the jar.

We know that,

80 percent of the jellybeans in a jar were consumed by students in a classroom.

Only 100 jelly beans are still available.

100/(1-80%)

100/0.2

100/1/5

100×5

500

Therefore, 500 jellybeans were originally present in the jar when 80 percent of the jellybeans in a jar were consumed by students in a classroom. Only 100 jelly beans are still available.
