Answer:

jesse or sam i think its sam by a little bit.

Step-by-step explanation:

Answer:

Sam

Step-by-step explanation:

Find all of their speeds to find how far they will go in 1 minute, by dividing the number of kilometers by the number of minutes:

Sam

4.2/6

= 0.7 km/min

Amanda

3.2/8

= 0.4 km/min

Jesse

3/5

= 0.6 km/min

Since 0.7 is the greatest number, that means Sam is the rider that will go the farthest in one minute.

Answer:

[tex]21.79 + c \leq 25[/tex]

Joshua can spend up to 3.21 on a card.

Step-by-step explanation:

[tex]21.79 + c \leq 25[/tex] is the correct equation because Joshua is spending 21.79 on flowers, a certain amount on the card, and the maximum he can spend is 25. That is why you use the less than or equal to sign.

To solve, first subtract 21.79 from both sides to get: [tex]c \leq 3.21[/tex]. This means that Joshua can spend up to 3.21 on a card.

Hope it helps!

Answer:

Average rate of change = [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

We have to calculate the average rate of change of the graph at x = 2 to x = 5.

From the graph attached,

At x = 2,

f(2) = 3

At x = 5,

f(5) = 7

Since, average rate of change of the function between x = a and x = b is defined by,

Average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex]

Therefore, average rate of change of the function represented by the graph will be = [tex]\frac{7-3}{5-2}[/tex]

           = [tex]\frac{4}{3}[/tex]

The graph of r = -3 + 5cosθ is symmetric about the option (B) x axis only

In mathematics, symmetry has a more precise definition, and is usually used to refer to an object that is invariant under some transformations; including translation, reflection, rotation or scaling.

Given that,

The graph of r = -3 + 5cosθ is symmetric about what?

When we plot the graph we can say that it is symmetric about x axis only.

Hence, the graph of r = -3 + 5cosθ is symmetric about the option (B) x axis only

Answer:

0.0001 = 0.01% probability of the Celtics winning eight straight championships.

Step-by-step explanation:

For each year, there are only two possible outcomes. Either the Celtics are the champions, or they are not. Each year is independent of other years. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

What would be the probability of the Celtics winning eight straight championships?

Each year, we have that [tex]p = 0.32[/tex]

Eight straight championships: [tex]P(X = 8)[/tex] when n = 8. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 8) = C_{8,8}.(0.32)^{8}.(0.68)^{0} = 0.0001[/tex]

0.0001 = 0.01% probability of the Celtics winning eight straight championships.

Step-by-step explanation:

Just multiple everything by 8

Answer:

8g+16

Step-by-step explanation:

I guess it can be kind of confusing when the number outside of the parentheses is on the right side of the equation? I don't know lol, but the same rules apply.

If it helps, rewrite it as: (2+g)8 --> 8(2+g)

Now multiply: (8*2)+(8*g)

Simplify: 16+8g or 8g+16 (however you want to write it)

Answer:

A

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

when moving things over the equation sign, you must switch the sign (positive or negative) they didn't switch it

Answer:

I think so Yes

Step-by-step explanation:

We'll use the exponent rule that a^(b+c) = a^b*a^c

to break up 17^16 into 17^(14+2) = 17^14*17^2

That allows us to factor like so

17^16+17^14

17^14*17^2+17^14*1

17^14(17^2 + 1)

Computing 17^14 is a lot more difficult compared to computing 17^2 + 1, assuming you only could use paper and pencil.

Note that 17^2 = 17*17 = 289, so 17^2 + 1 = 289+1 = 290

Because 290 ends in a 0, this means that 5 is a factor

290 = 5*58

This makes 5 to be a factor of the original expression.

----------------

So overall,

17^16+17^14 = 17^14(17^2 + 1) = 17^14*290 = 17^14*5*58 = 5*17^14*58

The stuff "17^14*58" doesn't matter. All we care about is that factor of 5.

Since 5 is a factor, this means that 17^16+17^14 is a multiple of 5, or 17^16+17^14 is divisible by 5.

Phrased another way, 17^16+17^14 all divided over 5 leads to some integer. In this case, the integer would be the result of 17^14*58.

The price per inch of butcher paper is $0.02.

"A word problem is a verbal description of a problem situation wherein one or more questions are posed, the answers to which can be obtained by the application of mathematical operations to information (usually numerical data) available in the text".

For the given situations,

A 6-foot roll of butcher paper costs = $1.44. Then

1-foot roll of butcher paper costs = [tex]\frac{1.44}{6}[/tex]

⇒ [tex]\$0.24[/tex]

1 foot = 12 inches

⇒ 12 inches roll of butcher paper costs = $0.24

Therefore, 1-inch roll of butcher paper costs = [tex]\frac{0.24}{12}[/tex]

⇒ [tex]\$0.02[/tex]

Hence we can conclude that the price per inch of butcher paper is $0.02.

1/5 of a box of candy

Step-by-step explanation:

Because John has 4 boxes of candy, he needs to divide this by his 20 classmates. So we have 4/20, which reduces to 1/5. So each classmate would get 1/5 of a box of candy (assuming that Josh himself does not get any candy).

18÷5= 3.6

3.6 = 4 yards

72 yards of cloth ÷ 4 yards of cloth = 18 pants

Step-by-step explanation:

3.6 yards rounded to the nearest is 4. So it takes 4 yards of cloth to make 1 pants. Since it takes 4 yards of cloth to make 1 pants, we simply divide 4 yards into 72 yards which equals to 18 pants.
