B and C seem to be the correct answers!

Hope this helps!

Answer:

a)3.10

b)31

Step-by-step explanation:

a) 1 half hour = 90 min

90÷30=3

9.30÷3=3.10

b)5 hrs -> 300 min

300÷30=10

10x3.10=31

Answer:

Option C. y = -2x + 3

Step-by-step explanation:

When we look at this function we see that it has a negative slope and the y-intercept is equal to (0,3).  From this we know that the function we are looking for will be looking like...

y = mx + 3

And as I said earlier since the slope is negative, the only right option is this case will be Option C

Answer:

The correct anwer is (C) : y = - 2x + 3

Answer:

square, parallelogram, rectangle, rhombus

Step-by-step explanation:

Considering the answer choices:

Square

Regular pentagon

Parallelogram

Rectangle

Rhombus

It can't be a pentagon because it only has four sides.

Properties of the shapes:

Rectangle - quadrilateral with two sets of congruent opposite sides and four right angles.

Rhombus - quadrilateral with four congruent sides.

Square - quadrilaterals with all properties of rectangles and rhombi.

Parallelogram - rectangles, rhombi, and squares are parallelograms.

This shape satisfies the properties of a square, meaning it is also a rectangle, rhombus, and parallelogram.

Answer:

2/7

Step-by-step explanation:

From 8 am to 3 pm, there are 7 hours, and the price changed $2 (52 - 50 = 2)

In order to find the Change in price per hour, divide the total price change by the number of hours. (in most questions with the word "per", it is a division problem)

2$ / 7hrs = 2/7 dollars per hour

Answer: x(8) - /81

Step-by-step explanation:

Answer:

Step-by-step explanation:

As before any expression of the form (a^2-b^2) will always factor to (a-b)(a+b) in this case

x^8-1/81 = (x^4-1/9)(x^4+1/9) = (x^2-1/3)(x^2+1/3)(x^4+1/9) and if we completely factor it including square roots.[tex](x-\sqrt{1/3})(x+\sqrt{1/3})(x^2+1/3)(x^4+1/9)[/tex]

Answer:

1.50 + 22

Step-by-step explanation:

Answer:

12 nickels. 9 dimes

Step-by-step explanation:

12 nickels is equal to 60 cents

9 dimes equals 90 cents

90 plus 60 equals 150 which is $1.50

Step-by-step explanation:

The First graph shows only the solutions to the inequality that makes sense for this situation.

What is Inequality?

Relation between two mathematical identities which is not equal that is it can be either greater than or less than or greater and equals to or less and equals to etc, is called Inequality.

In the given problem the variable is the number of cars.

Let us assume that the variable c represents the variable quantity which is the number of cars for the inequality.

Now we know that number of cars is always a positive and whole number.

So the suitable inequality to represent the condition that the number of cars is not more than 7 that is less than or equals to 7 is,

[tex]c \leq 7[/tex]

So the solutions are c=0,1,2,3,4,5,6,7

Hence the first graph shows the correct solution for the given inequality condition.

Answer:

  1) 240

  2) 211

Step-by-step explanation:

The counting sequence in base 5 is similar to that in base 10, except the digits 5 through 9 are not used. The first few counting numbers are ...

  1, 2, 3, 4, 10, 11, 12, 13, 14, 20, 21, 22, ...

When 1 is added to 4 in the units place, a carry to the fives place is generated and the units digit is returned to zero.

  234₅ +1 = 240₅

  210₅ +1 = 211₅

4 · 35 = 140

Hope this helps! Good luck. :)

Answer: since they're stacked, i cant tell if that's a fraction or decimal, or just whole numbers so...

4 times 35 = 140

4 times 3/5 = 2 2/5

4 times 3.5 = 14

Answer:

Systematic sampling

Step-by-step explanation:

Systematic sampling is a sampling technique in which the first sample selection is a random selection but other subsequent selection of samples occurs within a fixed sampling interval. The determination of this interval is based on the division of the population size by sample size.

Let assume that, our first random selection is [tex]i^{th}[/tex] unit, then the other fixed selection occurs at a fixed sampling interval of k.

Therefore, using systematic sampling method, the sampling unit will be every [tex]k^{th}[/tex] unit after the [tex]i^{th}[/tex] unit.

From  the question given:

We notice that the manager selects a sampling unit every 15th  hour. This tells us that he is taking the sampling unit by the usage of a fixed time interval.

Hence, this appears to be a systematic sample.

Answer:

Approximately 68% of their scores will fall within one standard deviation of the mean.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

By the Empirical Rule, approximately 68% of their scores will fall within one standard deviation of the mean.
