Answer 1

Answer:

[tex]\Large \boxed{\sf A}[/tex]

Step-by-step explanation:

[tex]\displaystyle \left(\frac{2}{3}\right)^4[/tex]

n → exponent, means to multiply the base number by itself n no. of times.

Here we multiply the base number by itself 4 times.

[tex]\displaystyle \frac{2}{3}\cdot \frac{2}{3}\cdot \frac{2}{3}\cdot \frac{2}{3}[/tex]

Answer 2

Answer: A.

To expand a exponent, you'll find the number how much it powers by and expand it by what the power or exponent number represents.

The fraction is 2/3 and the exponent is 4. Like I've said before, to expand it you'll find the number how much it powers by.

In the equation, 2/3 is going to the 4th power, so we will expand the fraction 4 times.

2/3 × 2/3 × 2/3 × 2/3

is 2/3 to the 4th power in expanded form.

Hence, A is the answer.

Answer:

volume: 200 cm³surface area: 220 cm²

Step-by-step explanation:

The usual formulas are useful for this.

V = LWH

V = (10 cm)(4 cm)(5 cm) = 200 cm³

The volume is 200 cubic centimeters.

SA = 2(LW +H(L +W))

SA = 2((10 cm)(4 cm) +(5 cm)(10 cm +4 cm)) = 2(40 +5(14)) cm² = 220 cm²

The surface area is 220 square centimeters.

Can the company conclude that their expected distribution was accurate using a 10% level of significance?

a. Calculate the test statistic.
b. Determine the critical value(s) for the hypothesis test.
c. Conclude whether to reject the null hypothesis or not based on the test

Answers

COLOR I need help with this qeustion also pls tell me when u get the answer

The test statistics is χ² = 8.31

The critical value is 6.251.

We reject the null hypothesis that the expected distribution is accurate.

What is hypothesis testing?

Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.

It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.

We have,

To test whether the expected distribution was accurate, we need to perform a chi-square goodness-of-fit test.

The null hypothesis is that the expected distribution is accurate, and the alternative hypothesis is that it is not accurate.

The expected frequencies are:

Color:

White Black Silver Rose Gold

105 122.5 70 52.5

i.e

Expected Freq:

0.3 x 350 = 105

0.35 x 350 = 122.5

0.2 x 350 = 70

0.15 x 350 = 52.5

Using the formula for the chi-square goodness-of-fit test statistic:

χ² = ∑ (Observed Frequency - Expected Frequency)² / Expected Frequency

χ² = [(99-105)²/105] + [(135-122.5)²/122.5] + [(89-70)²/70] + [(27-52.5)²/52.5]

χ² = 8.31

The critical value for the chi-square test with 3 degrees of freedom (4 categories - 1) and a significance level of 0.10 is 6.251.

Since the calculated test statistic (8.31) is greater than the critical value (6.251), we reject the null hypothesis that the expected distribution is accurate.

Therefore, the company cannot conclude that their expected distribution was accurate using a 10% level of significance.

Thus,

The test statistics is χ² = 8.31

The critical value is 6.251.

We reject the null hypothesis that the expected distribution is accurate.
