You have established that c = -2 in question 4.

From the graph, the point g(3)=0 seems usable, so let's go with that.

g(3) = a·b³ - 2 = 0, so a = 2/b³

g(2) = -1 seems also plotted, so g(2) = a·b² - 2 = -1 ⇒ a = 1/b²

Solve for b gives:

2/b³ = 1/b² ⇒ (multiply by b³) 2 = b

From this you can find a=1/4 

Note that this is only true if indeed g(3)=0 and g(2)=-1. I just assume that from the graph.

The fraction computed shows that the cups of sugar that can be used based on the flour will be B. 4 1/2 cups.

<h3>How to calculate the fraction?</h3>

From the information, Jonah used 1 1/2 cups of brown sugar and 2 1/3 cups for flour.

Therefore, the cups of sugar needed will be:

= 1.5/2.33 × 7

= 4.5 = 4 1/2.

If you add the standard deviation to the average, it is 14.84. Because Marcus's score was lower than that, he will not receive a certificate. 
I think this should be right for the reason and the calculation.

A circle has a center of (5,-5) and goes through (6,-2). What is the radius?
Fittoniya [83]
Start with the equation of a circle whose center is at (h,k) and whose radius is r:

(x-h)^2 + (y-k)^2 = r^2

Substituting the given coordinates of the center:

(x-5)^2 + (y-[-5])^2 = r^2, or (x-5)^2 + (y+5)^2 = r^2

Substituding the given coordinates of a point (6,-2) on the circle:

(6-5)^2 + (-2+5)^2 = r^2

Simplifying:

1^2 + 3^2 = r^2, or 1 + 9 = r^2, or 10= r^2.  Then r = sqrt(10).

Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card. What is the probabilit
DaniilM [7]

Answer:

\frac{1}{208}

Step-by-step explanation:

We have been given that Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card.

Let us find probability of getting a club.

\text{ Probability of getting a club}=\frac{13}{52} =\frac{1}{4}

Now let us find probability of getting the ace of spades.

\text{ Probability of getting ace of spades}=\frac{1}{52}

Now let us multiply these to find probability of getting a club and ace of spades.      

\text{ Probability of getting a club and then ace of spades}=\frac{1}{4}*\frac{1}{52}=\frac{1}{208}

Therefore, probability of getting a club and then the ace of spades \frac{1}{208}.
