Answer: p= -3,2

q= -3,8

R= -8,8

s=-8,2

Step-by-step explanation:

Given:

The numbers are [tex]-5,0,6,-3.5,-1\dfrac{2}{3}[/tex].

To find:

The number line one which each of the given number is plotted correctly.

Solution:

The given numbers are [tex]-5,0,6,-3.5,-1\dfrac{2}{3}[/tex].

To plot [tex]-5,0,6[/tex], we need to make dots at [tex]-5,0,6[/tex] respectively.

To plot [tex]-3.5[/tex], we need to make a dot in the mid of -4 and -3.

To plot [tex]-1\dfrac{2}{3}[/tex], we need to make a dot between -2 and -1. That point divides the segment between -2 and -1 in 1:2

In option A, -5 is not plotted correctly. So, option A is incorrect.

In option B, -3.5 is not plotted correctly and [tex]-1\dfrac{2}{3}[/tex] is not plotted. So, option B is incorrect.

In option C, all the points are plotted correctly. So, option C is correct.

In option D, [tex]-1\dfrac{2}{3}[/tex] is not plotted correclty. So, option D is incorrect.

Therefore, the correct option is C.

Answer:

Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.

Step-by-step explanation:

Given that Juan invested $ 19000 in two mutual funds, and Fund A earned 7% profit during the first year, while Fund B earned 3% interest, if he received a total of $ 1042 profit, to determine how much she had invested in each mutual fund the following calculation must be performed:

19000 x 0.07 + 0 x 0.03 = 1330

15000 x 0.07 + 4000 x 0.03 = 1170

11000 x 0.07 + 8000 x 0.03 = 1010

11500 x 0.07 + 7500 x 0.03 = 1030

11800 x 0.07 + 7200 x 0.03 = 1042

Therefore, Juan invested $ 11,800 in Fund A and $ 7,200 in Fund B.

Answer:

62

Step-by-step explanation:

surface area of a rectangular prism = 2lw + 2lh + 2wh

Where l = length, w = width and h = height

The box has the following dimensions

length = 5 in

width = 3 in

height 2 in

Using these dimensions, we plug in the values into the formula

[tex]SA=2(5*3)+2(5*2)+2(3*2)\\5*3=15\\15*2=30\\5*2=10\\10*2=20\\3*2=6\\6*2=12\\SA=30+20+12\\30+20+12=62[/tex]

Hence, the surface area = 62

Answer:

7/9

Step-by-step explanation:

this equation is true:

21/27 = 7/9

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.

7/9 = Proper Fraction

Answer: D) 888.6

Step-by-step explanation:

The expression which would help arrive at the required answer is y = 78b + c.

The least regression equation is the equation of best fit obtained from a linear regression graph.

The linear regression equation is expressed in the form :

y = bx + c ; where ;

y = Predicted variable

x = predictor variable

c = intercept

b = slope

The least regression equation is not given in the question above.

However, we could give the equation in the linear regression format :

y = number of visitors

y = number of visitors x = temperature = 78°

Hence, the equation becomes :

y = b(78) + c

y = 78b + c

Inputting the values of b and c in the equation will give the required answer.

Answer:

Step-by-step explanation:

The mixed number equivalent to 38 divided by 7 is 5 3/7.

To find the mixed number equivalent to 38 divided by 7,

we need to divide 38 by 7 and express the result as a mixed number.

=38 ÷ 7

= 5 remainder 3

Or      7 | 38 | 5

              35

         ______

                3

So, the quotient is 5 and the remainder is 3.

So, the mixed number equivalent to 38 divided by 7 is 5 3/7.
