Answer:

36 degrees

Step-by-step explanation:

180 - 58 = 122 degrees

122 - 90 = 32 degrees

32 + 4 = 36 degrees

Answer:

s = 36

Step-by-step explanation:

These lines is 180° in total and the one that is a right triangle has 90° and there is 58° on one so, 180 - 90 - 58 = 32.

32° = s - 4°

32 + 4 = s

36° = s°

Answer: The size and shape will only change when the transformation being made to the figure is a dilation. Since it is only being translated, its image and preimage are still congruent in size.

The term used to describe the 12.4% calculation made by Mrs. Raynor is the "point estimate" or "sample estimate" of the proportion of students with concerning behaviors in the classroom.

In statistical terms, a point estimate is a single value that is used to estimate an unknown population parameter based on sample data. In this case, Mrs. Raynor calculated the proportion of students with concerning behaviors in the classroom as 12.4% based on the reports from teachers. This percentage represents the estimated proportion of the entire student population in the school who may have behavior problems.

However, it is important to note that point estimates are subject to uncertainty and may not capture the true population parameter exactly. To account for this uncertainty, Mrs. Raynor also reported a margin of error, indicating that the actual proportion of students with behavior problems in the school could range from as low as 10.2% to as high as 14.6%. This range is known as the confidence interval, which provides a measure of the precision and reliability of the point estimate.

The right-angled triangle have angle B = 40°, side c = 20.9 and b = 13.4 approximately to the nearest tenth.

We shall use the trigonometric ratios of sine and cosine of the angle 50° to get the length of the sides and apply the rule of the sum of interior angles of a triangle to get the angle B.

sin50° = opposite/hypotenuse

sin50° = 16/c

c = 16/(sin50°) {by cross multiplication}

c = 20.9

cos50° = adjacent/hypotenuse

cos50° = b/20.9 {by cross multiplication}

b = 20.9 × cos50°

b = 13.4

The sum of interior angles of a triangle is equal to 180° so;

angle B = 180° - (90° + 50°)

angle B = 180° - 140°

angle B = 40°

Therefore, by application of trigonometric ratios sine and cosine, we have the sides of the right-angled triangle b = 13.4, c = 20.9, and the angle B = 40°.

Answer:

a. P(x = 5) = 0.24

b. P(x ≥ 6) = 0.43

c. P(x < 4)= 0.14

Step-by-step explanation:

According to the Question,

⇒We use Binomial Probability Formula

\(P(X = x ) = \frac{n!}{x!((n-x)! } * p^{x} * (1-p)^{n-x}\)

Where, p=0.52 & n=10

a. The probability that the number of U.S. adults who have very little confidence in newspapers is ​exactly​ five . So, (x=5)

Thus, \(P(X = 5 ) = \frac{10!}{5!((10-5)! } * 0.52^{5} * (1-0.52)^{10-5}\)

On Solving Above Equation we get,

P(5)=0.2441 ≈ 0.24

b. The probability that the number of U.S. adults who have very little confidence in newspapers is at least 6 . So, (x≥6)

Then,

P(x≥6) = P(6)+P(7)+P(8)+P(9)+P(10)

P(x≥6) = \(\frac{10!}{6!((10-6)! } * 0.52^{6} * (1-0.52)^{10-6}\) + \(\frac{10!}{7!((10-7)! } * 0.52^{7} * (1-0.52)^{10-7}\) +\(\frac{10!}{8!((10-8)! } * 0.52^{8} * (1-0.52)^{10-8}\) + \(\frac{10!}{9!((10-9)! } * 0.52^{9} * (1-0.52)^{10-9}\)+\(\frac{10!}{10!((10-10)! } * 0.52^{10} * (1-0.52)^{10-10}\)

On solving above equation we get,

P(x≥6) =  0.4270 ≈ 0.43

c. The probability that the number of U.S. adults who have very little confidence in newspapers is less than 4 . So, (x<4)

Then,

P(x < 4)=P(3) + P(2)+P(1)+P(0)

P(x<4) = \(\frac{10!}{3!((10-3)! } * 0.52^{3} * (1-0.52)^{10-3}\) + \(\frac{10!}{2!((10-2)! } * 0.52^{2} * (1-0.52)^{10-2}\)+ \(\frac{10!}{1!((10-1)! } * 0.52^{1} * (1-0.52)^{10-1}\) + \(\frac{10!}{0!((10-0)! } * 0.52^{0} * (1-0.52)^{10-0}\)

Therefore, the solution is "C(s) [s^5 + 354s^4 + 7s^3 + 2s² + 3s + 8] = [s^4 + 25³ + 4s² + s + 5] G(S)", which is a quadrilateral.

The transfer function of a system is the ratio of the Laplace transform of the output to the Laplace transform of the input, assuming all initial conditions are zero.

In the given transfer function

G(s) = R(S) s4 +25³ +4s²+s+5 s5+354 +7s3+2s²+3s+8, the numerator has a degree of four, whereas the denominator has a degree of five.

The corresponding differential C(s) equation is as follows:

C(s) = [s5+354 +7s3+2s²+3s+8] G(s)

Rearranging the terms, we get:

s^5 C(s) + 354s^4 C(s) + 7s^3 C(s) + 2s² C(s) + 3s C(s) + 8 C(s)

= [s^4 + 25³ + 4s² + s + 5] G

Rearranging further, we obtain the following:

C(s) [s^5 + 354s^4 + 7s^3 + 2s² + 3s + 8]

= [s^4 + 25³ + 4s² + s + 5] G(S)

The above equation represents the required differential equation for the given transfer function.
Note that the final answer must be enclosed in a quadrilateral, and the decimal answer should be rounded up to three decimal places.

To find the equation of the tangent line to the curve at the point (-27, -1), we need to find the slope of the tangent line and then use the point-slope form of a line.

First, we differentiate the given equation implicitly with respect to x:

(2/3)(x^(-1/3)) + (2/3)y^(-1/3) * (dy/dx) = 0

Next, we solve for dy/dx:

(dy/dx) = -(x^(1/3))/(y^(1/3))

Now, we can substitute the coordinates of the point (-27, -1) into the derivative to find the slope:

m = -(27^(1/3))/(-1^(1/3)) = -3

So, the slope of the tangent line is -3.

Using the point-slope form of a line, we have:

y - y1 = m(x - x1)

Substituting the values of the point (-27, -1) and the slope -3:

y + 1 = -3(x + 27)

Simplifying the equation:

y + 1 = -3x - 81

Finally, we can rearrange the equation to obtain the equation of the tangent line in slope-intercept form:

y = -3x - 82

Therefore, the equation of the tangent line to the curve at the point (-27, -1) is y = -3x - 82.

A. statistically significant difference in the mean blood hemoglobin levels between breastfed infants and formula-fed infants at α = 0.05.

B. the 95% confidence interval for the difference in population means between breast-fed infants and formula-fed infants is (−0.06, 1.18).

C. Both the hypothesis test and the confidence interval lead to the same conclusion that there is a difference in the mean blood hemoglobin levels between the two feeding regimens.

What is null hypothesis?

In statistics, the null hypothesis (H0) is a statement that assumes that there is no significant difference between two or more groups, samples, or populations.

(a) To test the hypothesis that there is a difference in the population means between breast-fed infants and formula-fed infants, we can use a two-sample t-test with equal variances. The null hypothesis is that the population means are equal, and the alternative hypothesis is that they are not equal. Using α = 0.05 as the significance level, the critical value for a two-tailed test with 40 degrees of freedom is ±2.021.

The test statistic can be calculated as:

t = (x1 - x2) / (Sp * √(1/n1 + 1/n2))

where x1 and x2 are the sample means, Sp is the pooled standard deviation, and n1 and n2 are the sample sizes. The pooled standard deviation can be calculated as:

Sp = √(((n1 - 1) * s1² + (n2 - 1) * s2²) / (n1 + n2 - 2))

where s1 and s2 are the sample standard deviations.

Plugging in the values from the table, we get:

t = (13.3 - 12.4) / (1.776 * √(1/23 + 1/19)) = 2.21

Since the absolute value of the test statistic is greater than the critical value, we reject the null hypothesis and conclude that there is a statistically significant difference in the mean blood hemoglobin levels between breastfed infants and formula-fed infants at α = 0.05.

(b) To construct a 95% confidence interval for the difference in population means between breast-fed infants and formula-fed infants, we can use the formula:

(x1 - x2) ± tα/2,Sp * √(1/n1 + 1/n2)

where tα/2,Sp is the critical value of the t-distribution with (n1 + n2 - 2) degrees of freedom and α/2 as the significance level.

Plugging in the values from the table, we get:

(x1 - x2) ± tα/2,Sp * √(1/n1 + 1/n2)

= (13.3 - 12.4) ± 2.021 * 1.776 * √(1/23 + 1/19)

= 0.56 ± 0.62

Therefore, the 95% confidence interval for the difference in population means between breast-fed infants and formula-fed infants is (−0.06, 1.18).

(c) The hypothesis test and the confidence interval both lead to the conclusion that there is a difference in the mean blood hemoglobin levels between breast-fed infants and formula-fed infants. In part (a), we rejected the null hypothesis that the population means are equal, which means we concluded that there is a difference. In part (b), the confidence interval does not contain 0, which means we can reject the null hypothesis that the difference in means is 0 at the 95% confidence level.

Therefore, both the hypothesis test and the confidence interval lead to the same conclusion that there is a difference in the mean blood hemoglobin levels between the two feeding regimens.
