Probability of Harper hitting a bullseye on any given toss is 1/4 then we would expect Harper to get 4 bullseyes during her next 16 tosses.

The probability of Harper hitting a bullseye on any given toss, based on the data provided, is:

P(bullseye) = 3/12 = 1/4

To find how many bullseyes we would expect Harper to get during her next 16 tosses, we can use the expected value formula:

Expected value = Number of trials x Probability of success

In this case, the number of trials is 16 and the probability of success (hitting a bullseye) is 1/4.

Expected value = 16 x 1/4 = 4

Answer:

D.   12/13

Step-by-step explanation:

Hyp = √( (-20)² + 48² )

Hyp = 52

Sin = opp/hyp

sin = 48/52 = 12/13

The value of trigonometric ratio Sinθ = 12/13.

Hence option D is correct.

According to the given point

The base of the triangle be = -20

Perpendicular of triangle = 48

We know that the Pythagoras theorem for a right-angled triangle:

(Hypotenuse)²= (Perpendicular)² + (Base)²

Therefore,

Hypotenuse = √( (-20)² + 48² )

Hypotenuse = 52

Since we know that,

Sinθ = opposite side of θ /hypotenuse

        =  48/52

        = 12/13

Hence,

Sinθ = 12/13

A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r².

Step-by-step explanation:

X=e+r/d

swap both sides

e+r/d=x

subtract e from both sides

e-e+r/d=x-e

r/d=x-e

multiply d to both sides

d×r/d=x-e×d

r=x-e×d

i got confused so i j filled in the table. mark as brainliest please :)

A function assigns the values. The last column in the table is needed to be filled as (-2,2), (0,4), and (2,10), respectively.

A function assigns the value of each element of one set to the other specific element of another set.

Given the value of x and the value of y is needed to be calculated using the function y=3x+4. Also, in the last column, the value of x and y is needed to be written in the form of a coordinate. Therefore, the value of y can be written as,

x=-2

y=3x+4

y=3(-2)+4

y = -2

x=0

y=3x+4

y=3(0)+4

y=4

x=2

y=3(2)+4

y=10

Hence, the last column in the table is needed to be filled as (-2,2), (0,4), and (2,10), respectively.

Answer:

123 m²

Step-by-step explanation:

Surface area of the object = surface area of the bigger rectangular prism + (surface area of the smaller rectangular prism - area of the smaller rectangular prism base)

Surface area of the bigger rectangular prism:

L = 7 m

W = 3 m

H = 3 m

S.A = 2(LW + WH + LH)

S.A = 2(7*3 + 3*3 + 7*3)

S.A = 102 m²

Surface area of the smaller rectangular prism:

L = 3 m

W = 3 m

H = 1 m

S.A = 2(LW + WH + LH)

S.A = 2(3*3 + 3*1 + 3*1)

S.A = 30 m²

Area of the base of the smaller rectangular prism = L*W

L = 3 m

W = 3 m

Area = 3*3 = 9 m²

Surface area of the object = 102 + (30 - 9)

= 102 + 21

= 123 m²

Step-by-step explanation:

BD is opposite the 30° angle. The sine of 30° is 0.5. The sin of an angle in a right triangle is opposite/hypotenuse so BD = sin 30°x8.

Answer:

The answer is -3

Step-by-step explanation:

When negative three is put into the equation, making it -3x + 17 = -3x + 19. there are no solutions because when solved the answer to that equation is 17 = 19, which is not true.

Step By Step Solving

-3x +17 = -3x + 19 - move the -3x to the other side by adding 3x to both sides.

17 = -3x + 3x + 19 - solve -3 + 3 and -x + x = 0 to get the answer

17 = 19 - which is not true so there are no solutions when the missing number is -3.

Answer:

Step-by-step explanation:

Because it contains the points (0, 0) and (pi/2, 1), the first graph is the graph of sin(x).

To identify the graph of sin(x), we need to remember some points of the sine function.

We know that sin(0) = 0, this means that this passes through the point (0, 0).

And we also know that sin(pi/2) = 1, then it also passes through the point (pi/2, 1).

With that in mind, the graph that passes through those two points is the first one, so that is the correct option.

Believe me! I got it right on the program!

Answer:

Step-by-step explanation:

1.5m

(2500mm)/(1000 mm/m) = 2.5m

(850mm)/(1000 mm/m) = 0.85m

4.8m

Add the number of meters:

1.5 + 2.5 + 0.85 + 4.8 = 9.65m

We have the given measurements 1.5 m, 2500 mm, 850, 4.8m. Therefore, the total length would be 9.65m.

One meter is equal to 1000 millimeters. So, to convert one millimeter into a meter we have to divide by 1000.

We have the given measurements 1.5 m, 2500 mm, 850, 4.8m

To convert a millimeter into a meter

2500 mm

= (2500mm)/(1000 mm/m)

= 2.5m

850mm

(850mm)/(1000 mm/m)

= 0.85m

Add the number of meters:

= 1.5 + 2.5 + 0.85 + 4.8

= 9.65m

Therefore, the total length would be 9.65m.

Answer:

D

Step-by-step explanation:

No, because the p-value of 0.08 is greater than the significance level of 0.05.

No, there isn't convincing statistical evidence at the significance level of a = 0.05 because the p-value of 0.08 > 0.05. (Option D)

Suppose the population proportion mean be denoted by [tex]\hat{p}[/tex]

and the population proportion random variable be denoted by p

Then, the z-test statistic's value for [tex]p = p_0[/tex] for sample of size n is specified by

[tex]z = \dfrac{\hat{p} - p_0}{\sqrt{\dfrac{p_0(1-p_0)}{n}}}[/tex]

For this case, we're specified that:

Thus, sample proportion is:

[tex]\hat{p} = \dfrac{38}{50} = 0.76[/tex]

(1) Null and Alternative Hypotheses

The following null and alternative hypotheses for the population proportion needs to be tested:

[tex]\begin{array}{ccl} H_0: p & \leq & 2/3\\ H_a: p & > & 2/3 \end{array}[/tex]

This corresponds to a right-tailed test, for which a z-test for one population proportion will be used.

(2) Rejection Region

Based on the information provided, the significance level is [tex]\alpha = 0.05[/tex], and the critical value for a right-tailed test is [tex]z_c = 1.64[/tex]

The rejection region for this right-tailed test is [tex]R = \{z: z > 1.645\}[/tex]

(3) Test Statistics

The z-statistic is computed as follows:

[tex]\begin{array}{ccl} z & = & \displaystyle \frac{\hat p - p_0}{\sqrt{ \displaystyle\frac{p_0(1-p_0)}{n}}} \\\\& = & \displaystyle \frac{0.76 - 2/3}{\sqrt{ \displaystyle\frac{ 2/3(1 -2/3)}{50}}} \\\\ & = & 1.401 \end{array}[/tex]

(4) Decision about the null hypothesis

Since it is observed that [tex]z = 1.401 \le z_c = 1.645[/tex], it is then concluded that the null hypothesis is not rejected.

Using the P-value approach: The p-value is p = 0.0806, and since [tex]p = 0.0806 \ge 0.05[/tex], it is concluded that the null hypothesis is not rejected.

(5) Conclusion

It is concluded that the null hypothesis H₀ is not rejected. Therefore, there is not enough evidence to claim that the population proportion pp is greater than 2/3, at the [tex]\alpha = 0.05[/tex] significance level.

Thus, there isn't convincing statistical evidence at the significance level of a = 0.05 because the p-value of 0.08 > 0.05. (Option D)
