Hello you guys can you help me with this thanks! Compare. Choose the correct symbol.

geniusboy [140]

Answer:

B) >

Step-by-step explanation:

You can compare fractions by converting them into a decimal and examining which one has the greater value.

3/4 = 0.75

3/5 = 0.6

From this, we can see that 3/4 is greater than 3/5, so the sign will be >.

----

note: You can also find the least common denomiator between the fractions and compare their numerator values to find which one is bigger. The one with the larger numerator will be the greater fraction.

hope this helps!

When the mean value of the dependent variable is independent of variation in the independent variable, the slope of the regressi

miss Akunina [59]

Answer:

zero

Step-by-step explanation:

The optimally fitted straight line via the locations and points on a graph is determined via linear regression. You may use regression equations to see if your data can indeed be fitted into a formula. If you want to create assumptions from your data, either future forecasts or indicators of previous behavior, using the Regression equation is highly beneficial.

The regression line is expressed as:

$Y_i = a +bx_i$

where;

$Y_i$ = dependent variable

a = intercept

b = slope

$x_i$ = independent variable

So, when $Y_i$ is independent of the variation of $x_i$ , it means that $Y_i$ does not linearly depend on $x_i$ . Thus, the slope of the regression will be zero.

This year June 1 is a Friday, and June has 30 days. If there will be exactly one hail storm in June, but we have no idea on whic

Ratling [72]

Answer:

The probability that the hail storm will happen on a Saturday is 0.1667.

Step-by-step explanation:

The month of June started on Friday.

Then June 2 is a Saturday.

Remaining 28 days.

Each week has 7 days.

There will be 4 full weeks for the month of June.

So there will be 4 more Saturdays.

Thus, there are a total of 5 Saturdays in the month of June.

Compute the probability that the hail storm will happen on a Saturday as follows:

$P(hail-storm)=\frac{n(Saturdays)}{Total\ no.\ of\ days} =\frac{5}{30}= 0.1667$

Thus, the probability that the hail storm will happen on a Saturday is 0.1667.
