Determine if its possible to form a triangle using the set of segments with the given measurement. explain please! 7 in., 8.7.,

mafiozo [28]

Start by adding together the shortest two sides, 7 and 8.7 inches. Result: 15.7 inches. Because this sum is greater than the longest side, 15.4 inches, it's possible to construct a triangle, whose largest angle will be close to 180 degrees.

The Poe family bought a house for $240,000. If the value of the house increases at a rate of 4% per year, about how much will th

Eddi Din [679]

Answer:

about $525,900

Step-by-step explanation:

Each year, the value is multiplied by (1 +4%) = 1.04. After 20 years, it will have been multiplied by that value 20 times. That multiplier is 1.04^20 ≈ 2.19112314.

The value of the house in 20 years will be about ...

$240,000×2.19112314 ≈ $525,900 . . . . . rounded to hundreds

given that a test statistic in a left tailed test is z equals -1.25, use a 0.05 significance level to find the p-value and state

mr Goodwill [35]

Answer:

The p-value of the test is 0.106.

The null hypothesis will be accepted at 5% level of significance.

Step-by-step explanation:

The hypothesis test is left-tailed.

The test statistic value is: z = -1.25.

The significance level of the test is: α = 0.05.

The p-value of a left-tailed hypothesis test is:

$p-value=P(Z$

The p-value of the test is 0.106.

**Use the z-table for the probability.

Decision rule:

If the p-value is less than the significance level the null hypothesis will be rejected and if it is more than the significance level the null hypothesis will be accepted.

The p-value = 0.106 > α = 0.05.

The null hypothesis will be accepted at 5% level of significance.
