Answer:

The length of each leg = 5 units

The length of the base = 4 units

Step-by-step explanation:

Isosceles Triangle is a triangle with any two sides of it in equal measure.

Perimeter of a triangle = SUM OF ALL SIDES

Now, Perimeter of the triangle = 14

Let length of each leg = a

So, the length of the other leg is also a.

And, the base of the triangle is a -1

Now, as perimeter is 14.

⇒a + a + (a -1) = 14

or, 3 a = 14 + 1

⇒ 3 a = 15, or a = 15/3 = 5

Hence, the length of each leg = 5

And the length of the base = (a -1) = (5-1) = 4 units

If the P-value of a test of significance is greater than the level of significance, then which of these conclusions are appropri

VLD [36.1K]

Answer:

Step-by-step explanation:

In general, when the p-value is "high" (ie greater than or equal to the significance level), our sample results could have occurred by random chance alone when null hypothesis H0 is true. So we cannot reject H0 with high p-values. That doesn't mean we can accept H0 as being true. Statistical hypothesis testing is used to determine whether the result of a data set is statistically significant. This test provides a p-value, representing the probability that random chance could explain the result. In general, a p-value of 5% or lower is considered to be statistically significant. If the P-value is less, reject the null hypothesis. If the P-value is more, keep the null hypothesis. 0.003 < 0.05, so we have enough evidence to reject the null hypothesis and accept the claim.A null hypothesis is a hypothesis that says there is no statistical significance between the two variables in the hypothesis. ... In the example, Susie's null hypothesis would be something like this: There is no statistically significant relationship between the type of water I feed the flowers and growth of the flowers.

In the arithmetic sequence {13, 6,-1,-8,...}, what is the common difference?

pav-90 [236]

════════ ∘◦❁◦∘ ════════

<h3>Answer = -7</h3>

════════════════════

<h3>Known</h3>

a = 13

U2 = 6

U3 = -1

U4 = -8

════════════════════

<h3>Question</h3>

d = ..?

════════════════════

#since it gives a lot of number, i will just pick one of the nth term, ill choose U2

Un = a + (n-1)d

U2 = 13 + (2-1)d

6 = 13 + d

6 - 13 = d

d = -7

════════════════════

• The formula of arithmetic sequence

n = nth term

a = first term

d = common difference

In university A, the number of graduate students was approximately 25 comma 000 fewer than the number of undergraduate students

alekssr [168]

Answer:

The number of graduate students attend university A is $G=n-25,000$

Step-by-step explanation:

Consider the provided information.

We need to determine how many graduate students attend university A?

The number of undergraduate students was n.

The number of graduate students was approximately 25,000 fewer than the number of undergraduate students.

Let G represents the number of graduate student.

$G=n-25,000$

Hence, the number of graduate students attend university A is $G=n-25,000$

Which of the following statements about the Lasso are true with respect to the OLS estimates?

mash [69]

Answer:

B and C

Step-by-step explanation:

B - The purpose of LASSO is to shrink parameter estimates towards zero, lasso shrinkage causes the estimates of the non-zero coefficients to be biased towards zero.

C- Lasso shrinks more accurately than the ridge. In the case of multiple coefficients Lasso selects only some some features and reduces the coefficients of the others to zero. This is called feature selection and it's not a possible in the ridge.
