The third one tells us the price is $12 per liter, that is to say, the top number is twelve times the bottom number.

.25 × 12 = $3

.7 × 12 = $8.40

2.5 × 12 = $30

3.52 × 12 = $42.24

$57.60 / 12 = 4.80 liters

A peony plant with red petals was crossed with another plant having streaky petals. A geneticist states that 75% of the offsprin
Strike441 [17]

Answer:

The sample data confirm the geneticist's prediction that 75% of the offspring from this cross will have red flowers.

Step-by-step explanation:

A Chi-square goodness of fit test can be used to test the claim made by the geneticist.

The hypothesis is defined as:

<em>H₀</em>: There is no difference between the observed and expected value,i.e. <em>p</em>₁ < 0.75.

<em>Hₐ</em>: There is a significant difference between the observed and expected value, i.e. <em>p</em>₁ > 0.75.

The test statistic is:

\chi^{2}=\sum \frac{(O-E)^{2}}{E}

Consider the tables attached below.

The value of the test statistic is:

\chi^{2}=\sum \frac{(O-E)^{2}}{E}=25.8133

The critical value is:

\chi^{2}_{\alpha, k-1}=\chi^{2}_{0.01, 1}=6.635

*Use a Chi-square table.

The critical region is:

\chi^{2}\geq 6.635

The test statistic value of 25.8133 lies in the critical region.

The null hypothesis is rejected at 1% level of significance.

<u>Conclusion</u>:

As the null hypothesis is rejected it can be concluded that 75% of the offspring from this cross will have red flowers.

wariber [46]

Answer:

A)  \frac{3}{12}

Step-by-step explanation:

Given:

Jing is helping the kindergarten teacher put together bags of crayons.

Each bag has 4 crayons, and 1/4 of the crayons in each bag are green.

What fraction of the crayons in 3 bags are green?

<u>Solution:</u>

1 bag contains number of crayons = 4

1 bag contains number of green crayons = \frac{1}{4} \ of\ 4 = \frac{1}{4}\times4=1

Total number of bags = 3

Total number of crayons in 3 bags = 4 \times 3 = 12

1 bag contains number of green crayons = 1

Total number of green crayons in 3 bags = 1  \times 3 = 3

Fraction of the green crayons out of total = 3 out of 12 = \frac{3}{12}

Therefore, fraction of the crayons in 3 bags are green are  \frac{3}{12}
