The sample space of the problem includes all the roses and hibiscus in a variety of colors. The sample space is equal to 315 flowers. There are 20 pink roses in the table so the probability of taking a pink rose out of the set is 20/315 or equal to 0.063

When it was 70 degrees outside, 50 members showed up at the beach club. for each degree temperature rose, another 10 members cam

stellarik [79]

Answer:

$f(t)=50+10(t-70)$

Step-by-step explanation:

Let the outside temperature be $t$ degree.

So, when $t=70$ degree, number of members, $f(t)=50$

Now, for every degree rise in temperature, 10 members gets added.

So, when the temperature is $t$ degrees, rise in temperature is $(t-70)$ degrees.

Therefore,

For $(t-70)$ degrees rise, number of members added = $10(t-70)$

Hence, total number of members added as a function of temperature is given as the sum of members at $t= 70$ degrees and for $(t-70)$ degrees rise. This gives,

$f(t)=50+10(t-70)$

Caroline needs to find 15% of $128, but she doesn't have a calculator. Thoroughly explain how she can do this mentally, detailin

IrinaK [193]

Answer:

The correct answer is $19.2.

Step-by-step explanation:

Caroline needs to find 15% of $128, but she doesn't have a calculator.

Caroline should start by finding the value of 10 % of any number as it is given by dividing the number by 10. Therefore 10% of $128 is given by $\frac{128}{10}$ = $12.8.

Now she can find the value of 5% of $128 which is given by dividing the 10% value of any number by 2. Thus 5% of $128 = $\frac{12.8}{2}$ = $6.4

Thus to calculate the value of 15% of $128 is given by adding 10% of 128 and 5% of 128 = $ (12.8 + 6.4) = $ 19.2.

Thus the value of 15% of $128 is $19.2.

Albert thought of a number, added 5, multiplied the result by 2, took away 6 and then divided by 2 to give an answer of 8

ValentinkaMS [17]

The answer is 6 ....you just have to do the steps backwards and it will result faster.
6+5=11
11*2=22
22-6=16
16/2=8

The graph of the step function g(x) = –⌊x⌋ + 3 is shown. On a coordinate plane, a step graph has horizontal segments that are ea

AleksAgata [21]

Answer:

{x| –2 ≤ x < 5}

Step-by-step explanation:

There is a box function plotted on the graph.

The function is g(x) = –⌊x⌋ + 3.

Now, we know that a box function represents a step graph having horizontal segments that are each 1 unit long. The left end of each segment is a closed circle. The right end of each segment is an open circle.

It is given that the left-most segment of the given graph goes from (-2,5) to (-1,5) and the rightmost segment goes from (4,-1) to (5,-1).

So, for the left most segment the domain is -2 ≤ x < -1

And for the right most segment the domain is 4 ≤ x < 5

Therefore, the total domain of g(x) will be {x| –2 ≤ x < 5} (Answer)
