The interquartile range is 6.

all you have to do is find the range of where that rectangle starts and ends, so 9-3=6. hope that helps :)

6.

The upper quartile is at 9. The lower quartile is at 3. The inner quartile range is the difference of those 2 numbers. 9-3=6

Two investments totaling $21,000 produce an annual income of $870. One investment yields 4% per year, while the other yields 10%
Citrus2011 [14]

Answer:

The amount invested at 4% is $20,500 and the amount invested at 10% is $500

Step-by-step explanation:

Let

x -----> the amount invested at 4%

(21,000 -x) ----> the amount invested at 10%

we know that

The interest of the amount invested at 4% plus the interest of the amount invested at 10% must be equal to $870

4\%=4/100=0.04

10\%=10/100=0.10

so

0.04(x)+0.10(21,000-x)=870

Solve for x

0.04x+2,100-0.10x=870

0.10x-0.04x=2,100-870

0.06x=1,230

x=\$20,500

21,000-x=\$500

therefore

The amount invested at 4% is $20,500 and the amount invested at 10% is $500

1. Suppose a and b are real numbers where a > 0 and b < 0.
Nat2105 [25]

a) –a + b is negative

b) a – b is positive

c) b-a is negative

Step-by-step explanation:

1. Suppose a and b are real numbers where a > 0 and b < 0.

a. Is –a + b positive or negative. Explain how you know.

We know a > 0 and b < 0. so, let a =6 and b = -5

Putting values:

–a + b

= -(6)+(-5) = -6-5 = -11

So, –a + b is negative

b. Is a – b positive or negative? Explain how you know.

We know a > 0 and b < 0. so, let a =6 and b = -5

Putting values:

a - b

=6-(-5) = 6+5 = 11

So, a – b is positive

c. Is b – a positive or negative. Explain how you know

We know a > 0 and b < 0. so, let a =6 and b = -5

Putting values:

b-a

=(-5)-(6)

= -5-6

= -11

So, b-a is negative

Find the measures of the angles a-k.
denis-greek [22]
A = 54 because alternate interior angles

b = 72 because 54+54=108 and 180-108=72

c = 108 because b and c are supplemental angles

d = 72 because b and d are corresponding angles

e = 162 because 72+90=162 and definition of a straight line

f = 18 because definition of a straight line

g = 81 because definition of an isosceles triangle

h = 49.5 because vertical angles and definition of an isosceles triangle

i = 130.5 because definition of a straight line

j = 31.5 because 49.5-18=31.5

k = 99 because corresponding angles
