Answer:

$\Huge \boxed{2210}$

Step-by-step explanation:

PEMDAS

To solve this problem, first you have to use the order of operations stands for parenthesis, exponents, multiply, divide, add, and subtract the numbers from left to right. Please Excuse My Dear Aunt Sally!

First, parenthesis.

$\displaystyle 50+80=130$

Next, multiply numbers from left to right.

$\displaystyle 17*130=\boxed{2210}$

Therefore, the correct answer is 2210.

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Answer:

The speed of a car is x miles per hour.

The total distance the car travels in

30 minutes is y. ....>>> y = 0.5x

The cost to produce a table, y, is two

times the cost to produce a chair, x. ..> y = 2x

The time required to bake a chocolate

muffin, y, is 2 minutes more than the

time required to bake a vanilla muffin, x.....>> y = x + 2

Tina’s age, y, is 5 years more than

her brother Tim’s age, x. .......>> y = x + 5

Step-by-step explanation: The only really tricky one is the "speed of the car ..." because the speed is given in miles per hour and the time is given in minutes so that is 0.5 hour times time

Otherwise, "times" means multiplication and "more than" means addition.

Select all of the following that are quadratic equations.

deff fn [24]

What you want to do is solve all of these so that it equals to 0 on one side. The ones that are a quadratic will have x^2

x^2 - 2x = 4x + 1
x^2 - 6x - 1 = 0
Yes this is a quadratic

x^3 - 6x^2 + 8 = 0
No this is not a quadratic because the highest power of x is to the power of 3

5x - 3 = 0
No it is not a quadratic because it does not have x^2

2x^2 + 12x = 0
Yes because there's x^2

5x - 1 = 3x + 8
2x - 9 = 0
No because no x^2

9x^2 + 6x - 3 = 0
Yes because there's x^2

The diameters of ball bearings are distributed normally. The mean diameter is 106 millimeters and the standard deviation is 4 mi

Assoli18 [71]

Answer:

Probability that the diameter of a selected bearing is greater than 111 millimeters is 0.1056.

Step-by-step explanation:

We are given that the diameters of ball bearings are distributed normally. The mean diameter is 106 millimeters and the standard deviation is 4 millimeters.

Firstly, Let X = diameters of ball bearings

The z score probability distribution for is given by;

Z = $\frac{ X - \mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = mean diameter = 106 millimeters

$\sigma$ = standard deviation = 4 millimeter

Probability that the diameter of a selected bearing is greater than 111 millimeters is given by = P(X > 111 millimeters)

P(X > 111) = P( $\frac{ X - \mu}{\sigma}$ > $\frac{111-106}{4}$ ) = P(Z > 1.25) = 1 - P(Z $\leq$ 1.25)

= 1 - 0.89435 = 0.1056

Therefore, probability that the diameter of a selected bearing is greater than 111 millimeters is 0.1056.

If a right circular cone is intersected by a plane that goes through both napped of the cone but not through the vertex, as in t

kramer

Answer:

F. Hyperbola

Step-by-step explanation:

In each napped, you'll have a parabola, combined they form an hyperbola.

It's one of the various shapes that can be produced by a plane intercepting a right circular cone, as you can see in the attached picture.

Each plane intersection is different, based on the angle and the position it passes through.

I hope that helps.
