Multiply eight and eighty-eight hundredths by two and three tenths
zimovet [89]

Answer:

20.424

Step-by-step explanation:

Given words can be written as

Eight and eighty-eight hundredths = (8+\frac{88}{100})

                                                            = \frac{800+88}{100}

                                                            = 8.88

Two and three tenth = (2+\frac{3}{10})

                                   =  \frac{20+3}{10}

                                   =  2.3

Now multiply them

i.e 8.88 × 2.3 = 20.424

So 20.424 is the Answer

Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)
dlinn [17]
Use the formula slope= y-y/x-x
-10-r/-2-8= 1/10
-10-r/-10= 1/10
Multiply the denominator (-10) on both sides
-10-r= -1
Add -10 to both sides
-r= 9
r= -9
Hope this helps!

A doctoral student wants to determine the relationship between steps per minute and the time it takes to walk 100 feet in
Rina8888 [55]

Using correlation coefficients, it is found that that the correct option is given as follows:

The correlation would stay the same because the change in units for time would have no effect on it.

<h3>What is a correlation coefficient?</h3>
  • It is an index that measures correlation between two variables, assuming values between -1 and 1.
  • If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
  • If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.

The correlation coefficient does not have units, hence if the units of the measures is changed, the coefficient remains constant, which means that the correct option is given by:

The correlation would stay the same because the change in units for time would have no effect on it.
