Answer:

The next fraction in the sequence is:

4/27

Step-by-step explanation:

How you can see, the fractions are decreasing as the sequence advance, to identify the proportion in which it decreases, we will divide the first and the second fractions:

3/4 / 1/2 = 3/2 or 1.5

Now, we just need to divide all the fractions in 3/2 to identify the next fraction, as I show below:

3/4 / 3/2 = 1/2
1/2 / 3/2 = 1/3
1/3 / 3/2 = 2/9
2/9 / 3/2 = 4/27

As you can see, all the results own to the sequence given, for this reason, the last result 4/27 is the correct fraction next to 2/9.

Which are points on the graph of y = 1.5 + ⌈x⌉? Check all that apply.

Romashka-Z-Leto [24]

Answer:

B, E

Step-by-step explanation:

The function y=1.5+x has two points listed which make the equation true.

(-1.5,0)

y=1.5+x

0=1.5+-1.5

0=0

(4.5,6)

y=1.5+x

6=1.5+4.5

6=6

Calculeaza 2+(8-6)= (9-7)+5= 10-(1+8)= (3+7)-9= (1+2+3)-5= 10-(2+3+4)=

Alex787 [66]

Answer:

1. 2+(8-6)= 4

2+2=4

2. (9-7)+5= 7

2+5=7

3. 10-(1+8)= 1

10-9=1

4. (3+7)-9= 1

10-9=1

5. (1+2+3)-5= 1

6-5=1

6. 10-(2+3+4)= 1

10-9=1

Find two numbers whose difference is 176 and whose product is a minimum.

Zanzabum

Let the two required numbers be x and y, then x - y = 176, thus y = x - 176.

Let the product of the two numbers be represented by

$P = xy x(x - 176) = x^2 - 176x$

For the product to be minimum, $\frac{dP}{dx} =0$

$\frac{dP}{dx} =2x - 176=0 \\ \\ \Rightarrow2x=176 \\ \\ \Rightarrow x=88$

Thus, y = 88 - 176 = -88

Therefore, the two numbers are 88 and -88.

For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along wit

Anni [7]

This question is incomplete, the complete question is;

For 50 randomly selected speed dates, attractiveness ratings by males of their female date partners (x) are recorded along with the attractiveness ratings by females of their male date partners (y); the ratings range from 1 to 10.

The 50 paired ratings yield x = 6.3, y = 6.0, r = -0.194, P-value = 0.176, and y^ = 7.40 - 0.218x.

Find the best predicted value of (attractiveness rating by female of male) for a date in which the attractiveness rating by the male of the female is x.

Use a significance level.

the best predicted value of y^ when x=8 is ?

( round your answer to one decimal place as needed.

Answer:

The best predicted value of y ^ when x equals 8 is 5.7

Step-by-step explanation:

From the information it is clear that equation for the regression line is

y^ = 7.40 - 0.218x.

where y^ represents the attractiveness rating by female of male partners and x represents the attractiveness rating by male of female partners.

The predicted value of y ^ when x equals 8 is obtained by substituting the value of x with 8 in the given regression equation.

The predicted value of y^ when x equals 8 is obtained below:;

The regression equation is y^ = 7.40 - 0.218x

Substitute x = 8x=8

y^ =7.40 − 0.218x

=7.40 − 0.218(8)

=7.40 − 1.744

= 5.656 ≃ 5.7

therefore The best predicted value of y ^ when x equals 8 is 5.7
