Haven't you tried to answer these yourself?

Let me give you 2 examples:

First: The product of sqrt(2) and sqrt(25) is 5sqrt(2), which is irrational because sqrt(2) is irrational.

Second: 2pi*r evaluated at pi^(-1) is rational because pi/pi = 1 and 2 itself is rational.

A study finds a correlation coefficient of r = .32. This number gives you information about which of the following? Group of ans

Mrac [35]

Answer:

Strength and direction of the relationship.

Step-by-step explanation:

Given that A study finds a correlation coefficient of r = .32. This number gives you information about which of the following?

Group of answer choices Type of relationship and importance Statistical validity and external validity Statistical significance and effect size Strength and direction of the relationship.

We know that correlation coefficient represented by r is a measure of association between two variables. r can lie between -1 and 1. While negative correlation suggests inverse relationship positive a positive association.

0 correlation means the two variables are independent.

If nearer to 0, it represents weak correlation and nearer to 1 than 0 represents strong correlation.

Here r =0.32 a weak positive correlation

r represents

Strength and direction of the relationship.

3/13, 5/13, 7/13, 9/13, <u>11/13</u>

3/13

3/13 + 2/13 = 5/13

5/13 + 2/13 = 7/13

7/13 + 2/13 = 9/13

Write the equation of a line in slope intercept form that passes through the points (0, 7) and (5, 3)

malfutka [58]

first you find the slope by making using the quation for slope

(7-3)/(0-5) and you find your slope is 4/-5. Then you can plug this into point slope form using on of the coordinates so:

y-y1=m(x-x1) --> y-3=-4/5(x-5)

then you distribute the -1 so -----> y-3=-4/5x+4 and then move the 3 over

so the answer is y= -4/5x+7

The planner needs a clearance of 9 feet under the arch. Has the planner met the minimum height?

Assoli18 [71]

Answer:

Yes,planner has met the minimum height, as minimum height was 9 feet and maximum height of arc is 9.6 feet

Step-by-step explanation:

The question is incomplete as all the details have not been given in the question.I have attached the complete question and its options at the bottom. Consult in for better understanding.

As we can see that at the mid value, for x=4, the value of f(x)=9.4

It means that the maximum height occurs at mid of the arc where it is height is 9.6 feet above the ground.

It means that the planner has met the minimum height, as minimum height was 9 feet and maximum height of arc is 9.6 feet
