Answer:

4x < -8

you will need to isolate the variable to be by itself by performing the inverse property of multiplication which is division;

/4 /4(divide by 4 from both sides)

x < -2

Order theses numbers least to greastest 3.18 3.1 3.108 2.1952

mel-nik [20]

Answer:

2.1952, 3.1, 3.108. 3.18

Step-by-step explanation:

Look at the ones place first, ignoring the decimal. The number is 2.1952. It is the lowest value among all the numbers. The other numbers are 3.18, 3.1, and 3.108. If we want to find the lowest among these three, we will have to minus one number from another, and if we see the result is positive, the first number in the calculation will be greater. So, 3.108-3.1= 0.008, which is positive. That means 3.108> 3.1. Again, 3.18-3.108= 0.72, which is also positive. So, 3.18> 3.108. So, the sequence will be 2.1952< 3.1 < 3.108 < 3.18

One sample has Aa Aa One sample has n 10 scores and a variance of s2 20, and a second sample has n 15 scores and a variance of s

siniylev [52]

Answer:

option (a) It will be closer to 30 than to 20

Step-by-step explanation:

Data provided in the question:

For sample 1:

n₁ = 10

variance, s₁² = 20

For sample 2:

n₂ = 15

variance, s₂² = 30

Now,

The pooled variance is calculated using the formula,

$S^{2}_{p} = \frac{(n_{1}-1)\times s^{2}_{1} +(n_{2}-1)\times s^{2}_{2}}{n_{1}+n_{2}-2}$

on substituting the given respective values, we get

$S^{2}_{p} = \frac{(10-1)\times 20 +(15-1)\times 30}{10+15-2}$

$S^{2}_{p}$ = 26.0869

Hence,

the pooled variance will be closer to 30 than to 20

Therefore,

The correct answer is option (a) It will be closer to 30 than to 20
