PLEASE HELP!!!

Answer:

Michael drove faster than Jordan.

Step-by-step explanation:

Speed

The speed is the ratio between the distance d traveled by an object and the time t it took to move. In terms of a mathematical equation, it's expressed as:

$\displaystyle v=\frac{d}{t}$

Michael drove 210 miles in 3 and one-half hours. The parameters to calculate the speed are: d= 210 miles, t = 3.5 hours. The speed of Michael is:

$\displaystyle v_M=\frac{210}{3.5}=60\ mi/h$

Jordan drove 330 miles in 6 hours, thus his speed is:

$\displaystyle v_J=\frac{330}{6}=55\ mi/h$

It's clear that Michael drove faster than Jordan.

Solve for x and graph the solution on the number line 15 > 2x – 9 > -23

Monica [59]

The answer is 12>x>-7

Step-by-step explanation:

it's first divided into 2 parts

1 . 15 > 2x - 9

2. 2x - 9 > -23

Then solve them individually.

let's do it,

First half

15 > 2x - 9

15+9 > 2x

24 > 2x

24/2 > x

12>x

Second half

2x-9>-23

2x>-23+9

2x>-14

x>-14/2

x>-7

Joining of the two halves

We have :

12>x>-7

Grace rolls a fair, 6-sided die 50 times.

Lostsunrise [7]

Answer:

Step-by-step explanation:

Here's the thing. It is easier to figure out the probability of not getting a six even once during the 50 rolls.

The chance of that happening is (5/6)^50 = 0.00010988

So the probability is succeeding is (1 - 0.00010988) = 0.9999 rounded to 4 places.
