No matter what number you substitute for the variable, the simplification will result is a false statement.

Help I don’t get these at all

You have a lot of questions here, so I'm going to help you with the bottom four.

Combine like terms:

3q - 8 - 6p + 8q - 4p

We can rearrange the terms to make this easier to simplify.

3q + 9q - 6p - 4p - 8

12q - 10p - 8 is the simplified version of the expression.

Simplify.

-32t/12t

The best way to simplify this is to look for the GCF of 32 and 12, which is 4.

-32/4 = -8

-12/4 = -3

The simplified form of this fraction is -8t/3t

[3(x - 4) - 2] + [5(x - 1) + 5]

There are two important things you need to know here.

First, you need to know PEMDAS.

Second, you need to know the distributive property.

First, we're going to use the distributive property.

[3x - 12 - 2] + [5x - 5 + 5]

Now, we just combine like terms.

3x - 14 + 5x

Then we do it again.

8x - 14 is the simplified version of the given expression.

30 + 19 * 26 - (-16)

This is more of a PEMDAS problem than the last, so we'll work through this in order.

First up is Multiplication.

Multiply 19 * 26

30 + 494 - (-16)

Next, we add, from left to right.

524 - (-16)

Because we have two negative signs, they cancel out and create a plus sign.

524 + 16

Add.

In a survey of 2264 adults, 729 say they believe in ufos. construct a 95 confidence interval for the population proportion of ad

Andreyy89

90% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the giver confidence interval [ 0.3026, 0.3348 ].

Here, we have given:

Number of adults (n) = 2272

Number of adults who believe in UFO (x) = 724

Sample proportion (p) = x/n

p = 724 / 2272

p = 0.3187

now, let q = 1 - p

q = 1 - 0.3187

q = 0.6813

Confidence level → 90%

The 90% confidence interval for population proportion is

$[ p - 1.645\frac{\sqrt{pq} }{\sqrt{n}} ,p + 1.645\frac{\sqrt{pq} }{\sqrt{n}} ]$

where 1.645 is Zac value at 90% confidence level.

$p - 1.645\frac{\sqrt{pq} }{\sqrt{n}}$ = 0.3187 - 0.0161 = 0.3026

$p + 1.645\frac{\sqrt{pq} }{\sqrt{n}}$ = 0.3187 + 0.0161 = 0.3348

90% confidence interval for the population proportion is

[ 0.3026, 0.3348 ]

Hence, With 90% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the giver confidence interval [ 0.3026, 0.3348 ]
