Answer:

1/4

Step-by-step explanation:

The probability that a student has a brother given that they do not have a sister 9/7.

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given;

[tex]\rm P(E)=\dfrac{Number \ of \ favourable \ events}{Number \ of \ total \ events}\\\\[/tex]

In a class of 22 students, 13 have a brother and 15 have a sister.

There are 3 students who do not have any siblings.

3 students don't have a sibling.

The probability that a student has a brother given that they do not have a sister is;

[tex]\rm P(E)=\dfrac{Number \ of \ favourable \ events}{Number \ of \ total \ events}\\\\ \rm P(E)=\dfrac{13+15-22+3}{22-15}\\\\\rm P(E)=\dfrac{31-22}{7}\\\\ P(E)=\dfrac{9}{7}[/tex]

So, the probability that a student has a brother given that they do not have a sister 9/7.

Answer:

From greatest to least

1) 3.498 3.49 3.4 3.149

2) 333.56 333.5 33.356 3.987

3) 804.7 80.47 8.047 0.8047

4) 700.088 700.08 700.008

5) 0.457 0.127 0.123 0.0678

Step-by-step explanation:

Explaining just 1st and 4th

The number 3.498 is bigger than 3.49 because it's basically this number 3.490

The same thing happens in 2nd and 3rd number 3.49 > 3.40

And the last number I think I don't have to explain :-)

700.088 is bigger because 700.08 is smaller

700.080

Answer:

The rate of change in the table is 78 students per year

Step-by-step explanation:

Here, we want to get the rate of change of the function

Mathematically, we can get this by using the formula;

m = (y2-y1)/(x2-x1)

(x1,y1) and (x2,y2) are points we are to select from the table

Let us select the point (4,704) and (17,1718) from the table

The slope is thus;

m = (1718-704)/(17-4) = 78 students per year

Answer:

18

Step-by-step explanation:

1/4 is close to 0 so 18 rounded to the nearest ones place is just 18

Answer:

20

Step-by-step explanation:

When we round to the nearest ten, we will round up to a number that has a zero in the ones place but we have to look at the number in the ones place before we round to determine the number in the tens place. The rule is if the number in the place before the place we need to round (in this case the ones place would be what we look at to determine the rounded tens place) 1-4 is going to round down, keeping the tens place the same and the ones place goes to zero, and if the ones number place is 5-9 then we round up, bringing the ones to zero and the tens up by one tens place.

Step-by-step explanation:

Under a translation < 5, - 9 >

5 is added to the original x- coordinate and 9 is subtracted from the original y- coordinate, that is

A(1, 4 ) → A'(1 + 5, 4 - 9 ) → A'(6, - 5 )

B(2, - 2 ) → B'(2 + 5, - 2 - 9 ) → B'(7, - 11 )

C(- 3, 2 ) → C'(- 3 + 5, 2 - 9 ) → C'(2, - 7 )

Answer: (3x^7-5x^5+10x^3-4x^2+1)÷(x^2-18)= 5x^1÷-9

Answer:

Step-by-step explanation:

First box is: decreasing

Second box: 0< b< 1

Third box: Up

Fourth box: Right

The parent function y=0.5^x is decreasing across its domain because its base b is such that (0<b<1) and function shifts it 8 units up and 5 units right.

Translation of a function is shifting the function from its original place in the graph.

Types of translation -

The functions of the graph given in the problem as,

[tex]f(x) = (0.5)^{x-5}+8[/tex]

The parent function of the graph is,

[tex]y=0.5^x[/tex]

In the parent function, the 5 units subtracted, and 8 units added outside the function. Thus, the function shifts the parent function 8 units up and 5 units right.

Thus, the parent function y=0.5^x is decreasing across its domain because its base b is such that (0<b<1) and function shifts it 8 units up and 5 units right.
