Yes, it is.

7/8=0,875
5/9=0,556

So: 0,875 is greater than 0,556

7/8= 63/72
5/9= 40/72

Because 63/72 > 40/72, 7/8 is greater than 5/9~

What is the solution to the compound inequality in interval notation? 2(2x−1)&gt;6 or <br> x+3≤−6
Vikentia [17]
4x - 2 > 6
4x > 8
x > 2

x + 3 <= -6
x <= -9 

so answer in interval notation is  (-∞, -9] or (2, ∞)

24 less than 4 times a number is 60. what is the number?
kondaur [170]
Hey there! :D

Make an algebraic expression. 

Let the 'number' equal x. 

4x-24= 60

Add 24 on both sides. 

4x= 84

Divide both sides by 4. 

x=21

The number is 21. 

I hope this helps!

Alladin's Amusement Park has a popular roller coaster ride. There are 2 trains. Each train has 7 cars. Each car holds 16 people.
Nataly [62]

Answer:

224

Step-by-step explanation:

Number of trains in the roller coaster = 2

Number cars in each train = 7

Total number of cars = Number of trains \times Number of cars in each train = 7\times 2 = 14

Number of people in each car = 16

Total number of people in 14 cars = Number of people in one car \times Number of cars = 16 \times 14 = 224

i.e.

Total number of people in the roller coaster in one run = 224

Number of runs made by each train in one hour = 10

Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.

224 \times 10 = <em>2240</em>

In testing a certain kind of missile, target accuracy is measured by the average distance X at which the missile explodes. The d
3241004551 [841]

Answer:

The answer is c) 761.0

Step-by-step explanation:

Mathematical hope (also known as hope, expected value, population means or simply means) expresses the average value of a random phenomenon and is denoted as E (x). Hope is the sum of the product of the probability of each event by the value of that event. It is then defined as shown in the image, Where x is the value of the event, P the probability of its occurrence, "i" the period in which said event occurs and N the total number of periods or observations.

 The variance of a random variable provides an idea of the dispersion of the random variable with respect to its hope. It is then defined as shown in the image.

Then you first calculate E [x] and E [x^{2}], and then be able to calculate the variance.

E[x]=0*\frac{1}{40} +10*\frac{1}{20} +50*\frac{1}{10} +100*\frac{33}{40}

E[x]=0+\frac{1}{2} +5+\frac{165}{2}

E[X]=88

So <em>E[X]²=88²=7744</em>

On the other hand

E[x^{2} ]=0^{2} *\frac{1}{40} +10^{2} *\frac{1}{20} +50^{2} *\frac{1}{10} +100^{2} *\frac{33}{40}

E[x²]=0+5+250+8250

<em>E[x²]=8505 </em>

Then the variance will be:

Var[x]=8505-7744

<u><em>Var[x]=761 </em></u>
