Answer:  Choice D  [tex](1-0.74)^4[/tex]

Reason:

74% = 0.74 represents the probability of him making any given free throw.

This means 1 - 0.74 is the probability of him missing.

Getting four misses in a row has a probability of (1-0.74)^4 which is the same as writing [tex](1-0.74)^4[/tex]

In other words, we multiply exactly four copies of (1-0.74) to get our answer.

Answer: x=23.25

Step-by-step explanation:

12-1/2(x-3)=1/4(2x+1)-10

4 ×12 -4×1/2(x-3)=4×1/4(2x+1)-10×4

48-2(x-3)=(2x+1)-40

48-2x+6=2x+1-40

48+6+40-1=2x+2x

93=4x

x=23.25

Answer:

Step-by-step explanation:

Using function concepts, it is found that the correct option is given by:

a.Yes, this graph represents a polynomial. There are two turning points and the least degree possible is three.

Supposing a polynomial with n turning points, the least possible degree is of n + 1.

In this problem, the polynomial has 2 turning points, hence the least possible degree is of 3 and option a is correct.

The pie chart is the most useful diagram on that will present the proportion of each observation in relation to the total data set and a line graph that displays the trend or the behaviour of the data set, called a line graph.

A line graph is a graph made up of segments of straight lines that connect the depicted data points.

As we know, that pie chart is the most useful diagram on that will present the proportion of each observation in relation to the total data set.

From the definition of the line graph, the graph that displays the trend or the behaviour of the data set, called a line graph.

Thus, the pie chart is the most useful diagram on that will present the proportion of each observation in relation to the total data set and a line graph that displays the trend or the behaviour of the data set, called a line graph.

Answer:

Just B and C

Step-by-step explanation:

Not A as cost is always increasing with x.

Yes B as is x squared relationship

Yes C as 15*9 = 135

No D as it is a squared relationship so much more than double

Not E as the the cost increases by a different amount for each increase in x.

To solve this problem, we have to apply mole-concept to this and we would need the molar mass of AlCl3.  2g of AlCl3 contains 9.034*10^21 molecules.

The molar mass of AlCl3 is given as 133.34g/mol

Data;

Using the mole concept, we can equate the molar mass to the number of molecules present in the entity.

[tex]133.34g = 6.023*10^2^3[/tex]

If we equate this

[tex]133.34g = 6.023*10^2^3\\2g = x molecules\\x = \frac{2*6.023*10^2^3}{133.34} \\x = 9.034*10^2^1 molecules[/tex]

From the calculations above, 2g of AlCl3 contains 9.034*10^21 molecules.

Harry would earn total money equal to $32.50 babysitting.

Since Harry charges 50% more for each additional hour as he did for the previous hour, then

he charges 1.5 or 3/2 times as much as he did for the previous hour.

Term Definition Money charge refers to a special expense entry and allows an administrator to track changes in a project's billing.

Harry charges $4 for the first hour.

Harry then charges

3/2 × $4 = $6 for the second hour.

Harry then charges 3

3/2 × $6 = $9 for the third hour.

Harry then charges 3

3/2 × $9 = $ 27/2 = $13.50 for the fourth hour.

Therefore, for 4 hours of babysitting

Harry would earn $4 + $6 + $9 + $13.50 = $32.50.

The [tex]275th[/tex] digit after the decimal point in the repeating decimal [tex]0.6295[/tex] will be [tex]9.[/tex]

Decimal is one of the types of numbers, which has a whole number and the fractional part is separated by a decimal point.

It is given that [tex]0.6295[/tex] is a repeating decimal.

i.e. [tex]0.6295[/tex] repeats after [tex]4th[/tex] digit,

So, divide [tex]275[/tex] by [tex]4[/tex],

We get,

   [tex]=\frac{275}{4}[/tex]

We get, [tex]68[/tex] and [tex]3[/tex] as remainder.

So, the [tex]275th[/tex] number after the decimal point will be [tex]3rd[/tex] digit in [tex]0.6295[/tex] after decimal.

i.e. [tex]275th[/tex] number will be [tex]9[/tex].

Step-by-step explanation:

The system of equations for eq 1 which is 3x + y = 118 represents the Green High School which filled three buses(with a specific number of students identified as x) and a van(with a specific number of students identified as y) with a total of 118 students.

for eq 2; 4x + 2y = 164; represents Belle High School which filled four buses(with a specific number of students identified as x) and two vans(with a specific number of students identified as y) with a total of 164 students.

The solution represents the specific number of students in the buses and vans in eq1 and eq 2 with x being 36 students and y being 10 students.

substituting 36 for x and 10 for y in eq 1;

3(36) + 10 = 108 + 10 = 118 total students for Green High School

substituting 36 for x and 10 for y in eq2;

4(36) + 2(10) = 144 + 20 = 164 total students for Belle High school

This are used to determine the maximum or minimum of a function. The vertex form of the function is given as y = 3(x+2)² - 5

This are used to determine the maximum or minimum of a function. Give the quadratic equation expressed as:
y = 3x² + 12x + 7

The vertex form of the function will be in the form y = a(x-h)² + k

Complete the square

y = 3(x² + 4x) + 7

y = 3(x² + 4x + 2² - 2²) + 7
y = 3(x+2)² - 3(4) + 7

y = 3(x+2)² - 5

Hence the vertex form of the function is given as y = 3(x+2)² - 5
