Answer: Jamar is correct

Step-by-step explanation:

Integer is a number that is a whole number and can either be positive or negative but it can't be a fraction or decimal. e.g 4, -2, 6, -23 etc.

A whole numbers are zero and other natural numbers such as 1, 4, 23. Negative numbers are not part of whole numbers.

From the statement made in the question, Sophia is wrong while Jamar is correct. The numbers aren't all whole numbers because some are negative.

What is 3x+2x+6=-18​
maksim [4K]

Answer:

x = -4.8

Step-by-step explanation:

combine like terms

3x + 2x + 6 = -18

5x + 6 = -18

isolate the terms with the x variable

5x + 6 - 6 = -18 - 6

5x = -24

isolate x

5x/5 = -24/5

x = -4.8

Ughh i suck at dilation
Ivenika [448]
Look at!!:
Pre image  A(3,4), B(1,5) C(6,6);
If you multiply these coordinates by 3/2, you get its images:

A(3,4)              ⇒ A`(3*3/2, 4*3/2)=(4.5, 6)
B(1,5)              ⇒B`(1.*3/2,  5*3/2)=(1.5, 7.5)
C(6,6)              ⇒C`(6*3/2, 6*3/2)=(9,9)

Therefore the scale factor is 3/2. 
When the scale factor of a dilation is >1, then we have an enlargement, an expansion.
In this case 3/2=1.5>1

Answer: 

The dilation is expansion.
The scale factor is 3/2.

Molodets [167]

Answer: 60,540< \mu

Step-by-step explanation:

The confidence interval for population mean is given by :-

\overline{x}-z^*\dfrac{\sigma}{\sqrt{n}}< \mu

, where \sigma = Population standard deviation.

n= sample size

\overline{x} = Sample mean

z* = Critical z-value .

Given :  \sigma=\$17,000

n= 49

\overline{x}= \$65,300

Two-tailed critical value for 95% confidence interval = z^*=1.960

Then, the 95% confidence interval would be :-

65,300-(1.96)\dfrac{17000}{\sqrt{49}}< \mu

=65,300-(1.96)\dfrac{17000}{7}< \mu

=65,300-4760< \mu

=60,540< \mu

Hence, the 95​% confidence interval for estimating the population mean (\mu) :

60,540< \mu
