Answer: 3/15 - 1/15 = 4/15

Step-by-step explanation: (I'm not 100% sure this is correct lol)

Answer:

Step-by-step explanation:

3/5 - 1/3

times the bottom two by eachother so they become 3/15 and 1/15

but since you times the bottome you have to times the top so it becomes

9/15 - 5/15 = 4/15

Step-by-step explanation:

Answer:

y = 77 degrees

Step-by-step explanation:

180 = 4x + 29 + 9x - 5

180 = 13x + 24

156 = 13x

x = 12

4x + 29 = y

48 + 29 = y

y = 77 degrees

Answer:

area of trapezium =1/2(a+b)*h

=1/2(7+10.4)*6.7

=1/2(17.4)*6.7

=1/2(116.58)

=116.58/2

=58.29 square cm

Answer:

58.29 cm²

Step-by-step explanation:

Hi there!

Area of a trapezoid: [tex]A=\displaystyle \frac{a+b}{2} *h[/tex]

We're given that a = 7, b = 10.4 and h = 6.7. Plug these into the above:

[tex]A=\displaystyle \frac{7+10.4}{2} *6.7\\\\A=\displaystyle \frac{17.4}{2} *6.7\\A=8.7*6.7\\A=58.29[/tex]

Therefore, the area of the trapezoid is 58.29 cm².

Step-by-step explanation:

that is really totally easy :

to get the value of the nth term, you just need to put the actual number instead of n in the calculation rule and calculate !

the 1st term :

3×1 + 2 = 3 + 2 = 5

the 2nd term :

3×2 + 2 = 6 + 2 = 8

the 3rd term :

3×3 + 2 = 9 + 2 = 11

the 10th term :

3×10 + 2 = 30 + 2 = 32

Answer:

if x = -2, y = -10

if x = 0, y = -4

if y = -1, x = 1

Step-by-step explanation:

if x = -2:

f(-2) = 3(-2) - 4

f(-2) = -6 - 4

f(-2) = -10

if x = 0:

f(0) = 3(0) - 4

f(0) = 0 - 4

f(0) = -4

if y = -1

-1 = 3(x) - 4

3 = 3(x)

x = 1

Answer:  Measure the length of the base. Call this value "b." Substitute these values into the equation for the area of a triangle: area = 1/2bh

Step-by-step explanation:

In geometry, the bottom of a three-dimensional object is called a base – if the top of the solid is parallel to the bottom it is also called a base. Since bases occupy a single plane, they have only two dimensions. You can find the area of a base by using the formula for the area of that shape.

Answer:

The correct answer is 95,677

Step-by-step explanation:

Greatest number of five digits: 75,320

Smallest number of five digits: 20,357

--

Remember:

Sum = Addition

Product = Multiplication

Difference = Subtraction

Sum of Greatest & Smallest:

[tex]75,320 + 20,357 = n[/tex]

[tex]n = 95,677[/tex]

Therefore, the correct answer is 95,677

The greatest number in the digits is 7, the smallest is 0.Their sum will be: 7+0=7

=7

The computer regression output includes the R-squared values, and adjusted R-squared values as well as other important values

a) The equation of the least-squares regression line is [tex]\underline {\hat y = 235 \cdot x + 10835}[/tex]

b) The correlation coefficient for the sample is approximately 0.351

c) The slope gives the increase in the attendance per increase in wins

Reasons:

a) From the computer regression output, we have;

The y-intercept and the slope are given in the Coef column

The y-intercept = 10835

The slope = 235

The equation of the least-squares regression line is therefore

[tex]\underline {\hat y = 235 \cdot x + 10835}[/tex]

b) The square of the correlation coefficient, is given in the table as R-sq = 12.29% = 0.1229

Therefore, the correlation coefficient, r = √(0.1229) ≈ 0.351

The correlation coefficient for the sample, r ≈ 0.351

c) The slope of the least squares regression line indicates that as the number of attending increases by 235 for each increase in wins

The product of the expressions (1/5 x - 1/4) and (2/3 x + 1) will be 2/15 x² + 1/30 x - 1/4.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The expression is given below.

(1/5 x - 1/4) and (2/3 x + 1)

Then the product of the expressions (1/5 x - 1/4) and (2/3 x + 1) will be

⇒ (1/5 x - 1/4) (2/3 x + 1)

⇒ 2/15 x² + 1/5 x - 1/6 x - 1/4

⇒ 2/15 x² + 1/30 x - 1/4
