Step-by-step explanation:

The probability that Whitney will win Prize 2 will be [tex]\frac{1}{9}[/tex]. Probability is the ratio of the favorable event to the total number of events.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.

Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

The total no of the contestants=3

Randomly selection of the prize-=1

The probability that Whitney will win Prize 2 will be;

[tex]\rm P= P(A)P(B) \\\\ P=\frac{1}{3} \times \frac{1}{3}\\\\ P= \frac{1}{9}[/tex]

Hence, the probability that Whitney will win Prize 2 will be [tex]\frac{1}{9}[/tex]

Answer:

D.  They do not have the same ratio of girls to boys because a straight line cannot be drawn through the points (14, 16), (17, 19), and (0, 0) on a coordinate grid.

Step-by-step explanation:

In order to check if the ratio is the same, convert the ratios to (x, y) points, plot them on a graph and see if you can draw a straight line through them and the origin (0, 0).  If you can, then the ratios are the same.  If not, then the ratios are not the same.

After plotting (14, 16) and (17, 19) and (0, 0) on a graph (attached), you can see that a straight line will only go through any two of the points, but not all three.  Therefore, the ratios are not the same.

The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.

Isaac Newton proved that fluids cool exponentially when left out in an open space.

A cup of coffee was poured at a temperature of 210°F and left on the dining room table to cool.

If you start drinking it at a temperature of 150°F, 10 minutes later.

The exponential function is given as

Then the initial temperature will be 210°F.

[tex]\begin{aligned} 150 &= \rm 210 (a)^{-10}\\\\0.7143 &= \rm a^{-10}\\\\-0.146 &= \rm -10 \log a\\\\0.0146 &= \rm \log a\\\\\rm a &= \rm 1.0342 \end{aligned}[/tex]

Then the equation will be

[tex]\rm T_f = 210 (1.0342)^{-t}[/tex]

Then the temperature will be when you take the last sip 18 minutes after you poured it.

Answer:

HCF=15    LCM=6,300

Step-by-step explanation:

Answer:

HCF = 15

LCM = 6300.

Step-by-step explanation:

Write them out as a product of their prime factors:

180 = 2*2*3*3*5

150 = 2*3*5*5

315 = 3*3*5*7

Picking out the factors common to all 3 list of prime factors:

The GCF = 3*5 = 15.

To find the LCM we pick out all the numbers except if there are repeated number we only use them once, So for example  we only take 2*2 for the calculation as there is a pair of 2's in 180 and 150 factors and there is an extra 2 in 180 - so we only take 2 of the 3 2's.

LCM = 2 * 2 * 3 * 3 * 5 * 5 * 7

= 6300.

Answer:

Step-by-step explanation:

In this context "solution" means a point whose x- and y-coordinates satisfy both equations.

If we're given the two linear equations x + y = 3 and 2x - y  = 7, we can solve them by addition and subtraction (among other methods):

3x = 3 + 7, or 3x = 10, or x = 10/3.  

Substitute this result into x + y = 3 to find the corresponding y value;  

10/3 + y = 3, or 10/3 + y = 9/3, or y = 1/3.  

Then the "solution" is the point (10/3, 1/3).
