Answer:

m<ADC = 42°

Step-by-step explanation:

Based on the inscribed angle theorem, the inscribed angle, m<ADC is ½ the measure of minor arc AC.

If minor arc is given as 84°, therefore:

m<ADC = ½(84)

m<ADC = 42°

Answer:

x = 0.4

Step-by-step explanation:

Answer:

x=0.4

Step-by-step explanation:

Given function:

Combine first value by 0.81:

Subtract 0.81 both from sides:

Simplifly -19x/2:

Multiply all terms by similar term:

Divide both terms by -7.6:

Therefore, x=0.4.

Answer:

BC > AD

Step-by-step explanation:

The opposite side to BC is greater, therefore making m<BCD > m<BAD. Since the legs are congruent, this is the only difference that need-be mentioned.

As the opposite angle of a larger side of a triangle is larger hence

m∠BAD > ∠mBCD.

We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.

From the figure itself, ΔABD and ΔBCD share a common side BD.

Given, Side AB is congruent to side CD and Side AD is greater than side BC.

We know opposite angle of a larger side of the triangle is larger.

Therefore, m∠BAD > ∠mBCD.

Answer: D

Step-by-step explanation:

The test statistic is t = 1.14.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean  and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean  and standard deviation .

here, we have,

Before testing the hypothesis, we need to understand the central limit theorem and subtraction of normal variables.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean  and standard deviation

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

From a random sample of 35 customers at Store M, the average amount spent was $300 with standard deviation $40.

This means that , μ_m = 6.761

From a random sample of 40 customers at Store V, the average amount spent was $290 with standard deviation $35.

This means that , μ_v = 5.534

Assuming a null hypothesis of no difference in population means

At the null hypothesis, we test that there is no difference, that is, the subtraction of the means is 0. So

H₀ = 0

At the alternate hypothesis, we test if there is difference, that is, the subtraction of the means is different of 0. So

H₁ ≠ 0

The test statistic is:

t = X - μ / s

In which X is the sample mean,  is the value tested at the null hypothesis, and s is the standard error.

0 is tested at the null hypothesis:

This means that μ= 0

From the samples:

X = 10

s = 8.737

The test statistic is t = 1.14.

A two-sample t-test for a difference in means will be conducted to investigate whether the average amount of money spent per customer at Department Store M is different from that at Department Store V. From a random sample of 35 customers at Store M, the average amount spent was $300 with standard deviation $40. From a random sample of 40 customers at Store V, the average amount spent was $290 with standard deviation $35. Assuming a null hypothesis of no difference in population means, what is the test statistic for the appropriate test to investigate whether there is a difference in population means?

Answer:

43°

Step-by-step explanation:

p + 7° + 3p+ 1° = 180° ( Being linear pair)

4p + 8° = 180°

4p = 180° - 8 °

4p = 172°

p = 172° / 4

p = 43°

Answer:

y = 6

Step-by-step explanation:

This is a special right triangle with angle measures 90° 60° 30°

the side length that sees angle measure 30 is represented with x

the side length that sees angle measure 90 is represented with 2x

and the side length that sees angle measure 60 is represented with x√3

the side length that sees angle measure 90 is given as 4√3 which means 2x = 4√3 divide both sides by 2

x = 2√3 now to find y, we need to multiply this value by √3

2√3 × √3 = 2 × 3
