-26 times a number minus 5 is equal to 56 less than the number

Airida [17]

-26x - 5 = x - 56

That should be the equation that is formed.

If you are attempting to find said number (x), then follow these steps:

First, add five to both sides:

-26x = x - 51

Then subtract x from both sides to get the variable on one side of the equation:

-27 x = -51

Now, divide both sides by -27, which will get you the final answer of:

x = -1.9 (rounded up)

Hope this helps!

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:

H₀: There is no difference between the observed and expected value,i.e. p₁ < 0.75.

Hₐ: There is a significant difference between the observed and expected value, i.e. p₁ > 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.

Conclusion:

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

The angle turns through 1/12th of the circle what is the measure of the angle

UNO [17]

Answer:

30°

Step-by-step explanation:

A full circle has 360°.

1/12 of a circle has 1/12 of 360°.

1/12 * 360° = 360°/12 = 30°

Answer: 30°
