Answer:

it depends on how many females are there

Step-by-step explanation:

I need to know how many females are there

Answer: If there are x total members, then the number of males is 5/8x

Answer:

y = -1/2x - 1

Step-by-step explanation:

We can use the point-slope form of the equation:

y-y1 = m(x-x1)

Where the given y1 = -2, x1 = 2, and m = -1/2. This yields:

y - (-2) = -1/2(x - 2)

y + 2 = -1/2x + 1

y = -1/2x +1 - 2

y = -1/2x - 1

Answer: he can choose from three combinations

Step-by-step explanation: since three is the lowest number it can be paired with three others combinations  

The number of different outfits Tyler choose is equal to 840

From the question, we have the following parameters that can be used in our computation:

Given 3 pairs of pants, 7 t-shirts, 8 sweaters or hoodies, and 5 pairs of shoes.

Thus, the number of different outfits is the products of the count of each apparel.

This is represented as;

Different outfits = Pants * T-shirts * Sweaters or hoodies * Pairs of shoes

Substitute the known values in the above equation;

Different outfits = 3 x 7 x 8 x 5

Evaluate;

Different outfits = 840

Hence, there are 840 different outfits

Step-by-step explanation:

Area of rectangle= l x b

= 245 x 245

=60025

Area of triangle = (1/2) x b x h

=(1/2) x 245 x 245

=30012.5

Area of shaded part = Area of rectangle - Area of triangle

=60025 - 30012.5

=30012.5

Answer:

B, D and E

Step-by-step explanation:

Using the rules of exponents/ radicals

[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

[tex]a^{\frac{1}{2} }[/tex] = [tex]\sqrt{a}[/tex]

Given

[tex]49^{-\frac{1}{2} }[/tex] = [tex]\frac{1}{49^{\frac{1}{2} } }[/tex]  → E

= [tex]\frac{1}{\sqrt{49} }[/tex]  → B

Answer:

175 cm

Step-by-step explanation:

identity used is

x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).

then use

(x+y+z)² = x²+y²+z²+2(xy+yz+xz)

225= 83 + 2(xy+yz+xz)

xy+yz+xz = (225-83)/2

xy+yz+xz= 142/2

xy+yz+xz= 71

ok

now use identity

x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).

now

x³ + y³+ z³– 3xyz = 15 (83 – xy – yz – zx).

= 15[83 - (71)]

= 15×12

Answer:

4

Step-by-step explanation:

Volume of cylinder = 2πrh = 2π(4)(6) = 48π

Volume of cone = πr²h/3

Height of cone = √(5² - 3²) = 4

Volume of cone = π(3²)(4)/3 = 12π

Cones to fill cylinder = 48π ÷ 12π = 4

Answer:

1.

Step-by-step explanation:

Take two points off of the line. I will use

(1, -2) and (4, 1).

Put them into the slope formula, which is (refresh if you cannot see.)

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the values.

[tex]\frac{1-(-2)}{4-1}[/tex]

Subtract both the numerator and the denominator.

[tex]\frac{3}{3}[/tex]

Simplify to get

1.

The slope of the line provided is 1.

Answer: 4

Step-by-step explanation:

By finding the relative frequency, we will see that we can expect that 4 out of the next 20 sundaes will have nuts.

First, we know that 2 out of the last 10 sundaes sold had nuts. So the relative frequency of sundaes with nuts is:

R = 2/10 = 0.2

(the quotient between the number of sundaes with nuts and the total number of sundaes)

Then, out of the next 20 sundaes, we can expect that the number of sundaes with nuts will be:

N = R*20 = 0.2*20 = 4
