Answer:

2:5 means [tex]\frac{2}{5}[/tex]

so when you write [tex]\frac{2}{5} =[/tex][tex]\frac{32}{x}[/tex]

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

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.

hi! so what you want to do is first set up a proportion, if you know that the two triangles are congruent because abc~def you know that the proportion will work out. the proportion to set up is 54/72 from there you should know that 9 goes into both 72 and 54 so when you reduce you’d be left with 6/9 which you could further reduce to 2/3. then you can find the other sides by multiplying 92 by 2/3 and you’d get 61 and 84 by 2/3 where you’d get 56. However since you are supposed to find the perimeter, you would add all three sides together (54+56+61) and you’d be left with 171. hope this helps

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.
