HELP PLEASE!!!!!

Mathematics
1 answer:
Tasya [4]3 years ago
6 0

Answer:

233 Times

Step-by-step explanation:

In a standard cube, there are 6 faces labelled 1 to 6.

Numbers less than 5=1,2,3,4

The probability of rolling a number less than 5 =4/6

Therefore, if the standard number cube is rolled 350 times.

Number of Expected Outcome Less than 5

=\dfrac{4}{6}X350

=233.33\\\approx 233$ (to the nearest integer)

We would roll a number less than 5 233 times.

Darya [45]

Answer: 9 and 7eights

Step-by-step explanation: Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction. Which would equal, 9 and 7eights.

Write the equation in slope-intercept form for each line based on the information given.
nexus9112 [7]

Answer:

y = -1x + 6 or y = -x + 6

Step-by-step explanation:

First, let's identify what slope-intercept form is.

y = mx + b

m is the slope. b is the y-intercept.

We know the slope is -1, so m = -1. Plug this into our standard equation.

y = -1x + b

To find b, we want to plug in a value that we know is on this line: (2, 4). Plug in the x and y values into the x and y of the standard equation.

4 = -1(2) + b

To find b, multiply the slope and the input of x(2)

4 = -2 + b

Now, add 2 from both sides to isolate b.

6 = b

Plug this into your standard equation.

y = -1x + 6

This is your equation.

Check this by plugging in the point again.

y = -1x + 6

4 = -1(2) + 6

4 = -2 + 6

4 = 4

Your equation is correct.

Hope this helps!

A parabola whose equation is y = (x - 5)^2 - 2 has a vertex at _____.
jasenka [17]
(5, -2) because y=(x-5)^2-2 is really y=x^2-10x+23 after you foil then take the derivative which is y'=2x-10 solve for x and you get 5 then put 5 in the original equation and you get -2 so the answer is (5, -2)<span />
