1. D; -5m+2m, because -5+2=-3

2. B; 4 terms, every part of an expression that's not the subtraction/addition sign counts as a term.

3. Not 100% sure about this one, but I'll go with B; 4x².

4. C; 5b, that term cannot be combined because the variable is different from the rest.

I hope this was helpful.

The five has to be minus, the two is plus. m has to be both. That makes D the answer. The others give 3m 7m and 3m. 
Answer D

Two
This question is VERY important. Don;t leave it alone until you understand it.
2x and x can combine. Nothing else can combine with anything else. The answer you get is

3x - 5y + 3

There are 3 different terms. Nothing else will combine because either the letters are different (x and y) or the 3 has no letter with it. This is your answer. Algebra is real picky about that.

Answer A

Three
Another biggy. x^2 is not the same thing as x. The other three will combine by addition. x^2 must be left alone along with 4.
Answer B 4x^2
If you were actually to do this, you would get 9x + 4x^2
Four
5b. the letters are not the same.

Answer:

C.

discrete data

Step-by-step explanation:

The given function is:

                                                  C(p) = 0.95p

Where p represents the number of bolts purchased. We can calculate the cost based on the number of bolts purchased.

An important distinction between discrete and continuous data is that the continuous data is measured while discrete data is calculated or counted. Since we are obtaining the data by calculation, it must be discrete data.

The function can take on only specific values. For example for p=0, C is 0 and for p=1 the value of C is 0.95. The function cannot take any value in between 0 and 0.95. This is a characteristic of discrete function. A continuous function can take all possible values in an interval.  

Therefore, the answer to this question is: The Function models discrete data.

Answer:

diagonal = = 12.8 inches (to the nearest tenth of an inch)

Step-by-step explanation:

As shown in the diagram attached to this solution:

Let the Length of the rectangular board = a

Let the width = b

Let the diagonal = d

where:

a = 10 inches

b = 8 inches

d = ?

Triangle ABC in the diagram is a right-angled triangle, therefore, applying Pythagoras theorem:

(hypotenuse)² = (Adjacent)² + (Opposite)²

d² = 10² + 8²

d² = 100 + 64

d² = 164

∴ d = √(164)

d = 12.806 inches

d = 12.8 inches (to the nearest tenth of an inch)

<em>N:B Rounding off to the nearest tenth of an inch is the same as rounding off to 1 decimal place.</em>

SCORPION-xisa [38]

Answer:

The answer is "96.864 ml".

Step-by-step explanation:

In this question, the formula of \bold{CI = X \pm t \times s}.

( where X is the mean, t is the coefficient, and s is the mean difference error)

As a result, only 2.5% of containers might include less than 100 ml of volume, its trust coefficient could indeed be used in accordance with 95%, which is t=1.96.  

And it can take \pm \ 1.6 \ ml to have been the full value the standard infinite:  \to CI = 100 \pm (1.96 \times 1.6) \\\\

         = 100 \pm (3.136) \\\\

Consequently, if the standard error is  \pm \ 1.6 \ ml , a similar amount should be used to fill  

= 100 - 3.136 \\\\= 96.864 \ \ mL
