Answer:

18

Step-by-step explanation:

because there where two houses each invited 9 guests and 9 + 9 = 18

Mean: 80 grams

Standard Deviation: 1.25 grams

The mean stays the same.

How to find standard deviation in this case would be:

SD divided by the squareroot of the sample.

So, 5/[tex]\sqrt{16}[/tex] = 1.25

Answer:

$51,282

Step-by-step explanation:

100*1.75%=1.75*504 months (42 years)=882

100*504 months (42 years)=50,400

50,400+882=$51,282

Hope this is correct, and helps you out :)

Interest is the price you pay to borrow money or the cost you charge to lend money.

Initial investment (PV)= $100

Number of periods (n)=42 years

Interest rate (i)= 1.75%

So, FV= P(1+r/100)^(nt) -1)) / (r/n)

FV= 100(1+0.0175/100)^(12*42) -1)) / (0.0175/12)

FV= $74,356.50

The Bay of Pigs invasion begins when a CIA-financed and -trained group of Cuban refugees lands in Cuba and attempts to topple the communist government of Fidel Castro. The attack was an utter failure. Fidel Castro had been a concern to U.S. policymakers since he seized power in Cuba with a revolution in January 1959.

Answer:

y = x² + 2x + 1

Step-by-step explanation:

Same y value at x = -2 & x = 0

So line of symmetry is at:

x = (-2+0)/2

x = -1

Vertex: (-1,0)

y = a(x - -1)² + 0

y = a(x + 1)²

At x = 1, y = 4

4 = a(1 + 1)²

4 = 4a

a = 1

y = (x + 1)²

y = x² + 2x + 1

The general form of the equation of the quadratic function is x² + 2x + 1

The formula expressing the equation of the quadratic function will be expressed as:

y = a(x -h)² + k

From the table shown, we can see that the y-values are the same at where x = -2 and 0

Get the line of symmetry:

[tex]x =\frac{-2+0}{2}\\x=\frac{-2}{2} \\x=-1[/tex]

We can see that when x = -1, y = 0. Hence the vertex will be at (-1, 0)

h = -1

k = 0

Substitute into the formula y = a(x -h)² + k

y = a(x -(-1))² + 0

y = a(x+1)²

From the table at where x = 1, y = 4. On substituting to get "a" we have:

4 = a(1+1)²

4 = 4a

a = 1

Get the required quadratic function by substituting the parameters into the general formula as shown:

y = a(x -h)² + k

y = 1(x +1)² + 0

y = (x+1)²

y = (x+1) (x+1)

y = x² + x +x + 1

y = x² + 2x + 1

Hence the general form of the equation of the quadratic function is x² + 2x + 1

Answer: 1256cm

Step-by-step explanation:

Final answer:

When Josie doubles the radius of the bird bath to build a larger one, the new surface area will be 1256 cm², as surface area quadruples when doubling the radius of a circle.

Explanation:

Josie calculated that the surface area of her small bird bath with a radius of 10 cm is 314 cm^2. If she doubles the dimensions for a larger bird bath, the new radius will be 20 cm. To find the surface area of the larger bird bath, we use the formula for the area of a circle, A = πr².

Plugging in the new radius:

A = 3.14 × (20 cm)^2

A = 3.14 × 400 cm^2

A = 1256 cm2

This means the surface area for the larger bird bath Josie plans to build will have 1256 cm^2 for bird bathing. This calculation demonstrates how the surface area of a circle quadruples when the radius is doubled, which is consistent with the principle that surface area scales with the square of the dimension changes.

Answer:

s ≥ 170

Step-by-step explanation:

The problem raises the following statement: "The cruising speed of the bullet train will be at least 170 miles per hour"

Which means that the train has a speed of 170 miles for now or higher, knowing this we can pose the inequality.

Knowing that "s" is the train's cruising speed (in miles per hour), we have to:

s ≥ 170

This would be the inequality that the statement represents.

The inequality representing the bullet train's cruising speed being at least 170 miles per hour is s ≥ 170.

The situation described involves finding an inequality for the train's cruising speed. To represent the train's cruising speed in miles per hour, we use the variable s.

Given that the cruising speed of the bullet train will be at least 170 miles per hour, we need an inequality that expresses this condition.

The inequality is:

s ≥ 170

This means that the cruising speed s can be 170 miles per hour or higher.

The length of arc QS in circle R is approximately 22.9 units. This is determined by using the formula for arc length in a circle, which is the radius times the angle (in radians). The angle was first converted from degrees to radians.

To find the length of arc QS in circle R, we need to use the formula for the arc length. The arc length of a circle is given by the formula Length = radius * angle (in radians). The angle is provided as 82 degrees, and the radius QR is given as 16 units.

First, we need to convert the angle from degrees to radians. We use the formula: radians = degrees * (π / 180). Hence, 82 degrees is approximately 1.43117 radians.

Now, let's substitute our values into the formula. Length = 16 units * 1.43117 radians.

Hence, the arc length of QS is approximately 22.9 units when rounded to the nearest hundredth.
