Answer:

Step-by-step explanation:

nCr = n! / r!(n-r)!

n=46

r=6

=46!/6!(46-6)!

=46!/[6!(40)!]

=(46*45*44*43*42*41*40!)/(6*5*4*3*2*1)(40!)

Cancel out 40!

=46*45*44*43*42*41/(6*5*4*3*2*1)

=6744109680/720

=9366819

The total number of students in Ms. Morales's class is either 20 or 30, depending on the value of x.

Let the ratio of boys to girls in Ms. Morales's class be 3x:7x, where 3x represents the number of boys and 7x represents the number of girls.

The total number of students in the class is equal to the sum of the number of boys and the number of girls, which is 3x + 7x = 10x.

We don't know the value of x, but we do know that the class size is between 22 and 34 students.

Therefore, we can set up an inequality based on the total number of students:

22 ≤ 10x ≤ 34

Dividing all parts of the inequality by 10, we get:

2.2 ≤ x ≤ 3.4

Since x represents a whole number of students, the possible values for x are 3 (if there are 30 students in the class) or 2 (if there are 20 students in the class).

If x = 3, then the total number of students is:

10x = 10(3) = 30

If x = 2, then the total number of students is:

10x = 10(2) = 20

Answer:

p = 121

Step-by-step explanation:

inveresly proportional

pq² = k

find k the constant of proportionality

p is 16 when q is 11,

16 * 11² = k

k = 1,936

----------------------------

pq² = 1,936

determine p when q is equal to 4.

p * 4² = 1,936

16p = 1,936

p = 1,936/16

p = 121

Answer:

p= 121

Step-by-step explanation:

p\(\alpha\) \(\frac{1}{q^{2} }\)

p=k/\(q^{2}\)

k=p\(q^{2}\)

Get the value of your constant k

k=(16)(\(11^{2}\))

k= 1936

p= \(\frac{1936}{q^{2} }\)

When q=4

p=  \(\frac{1936}{4^{2} }\)

p= 121

➟ 400,000

Step-by-step explanation:

it seems you solved the tricky part yourself already.

just to be sure, let's do the first derivative here again.

the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...

f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =

= 3t⁴ + 18t³ + 24t² + 18t + 21

f'(t) = 12t³ + 54t² + 48t + 18

and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).

we simply put the input number (2) at every place of the input variable (t).

so,

f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =

= 426

Answer: The missing number is 5.

Step-by-step explanation:

In the table we can only have numbers between 1 and 9,

The pattern that i see is:

We have sets of 3 numbers.

"the bottom number is equal to the difference between the two first numers, if the difference is negative, change the sign, if the difference is zero, there goes a 9 (the next number to zero)"

Goin from right to left we have:

9 - 6 = 3

6 - 2 = 4

4 - 9 = - 5 (is negative, so we actually use -(-5) = 5)

4 - 4 = 0 (we can not use zero, so we use the next number, 9)

3 - 3 = 0 (same as above)

? - 1 = 4

? = 4 + 1 =  5

The missing number is 5.

The probability of dealing with a straight from a deck of 52 cards = 0.00394

Step-by-step explanation:

An ace must occur to have a straight, the Ace can either be high or low which can appear at the beginning or near the end. The rank of straight for an ace to occur range from 2,3,4,5,6,7,8,9,10.

If a suit is already at hand, and we have the opportunity to select four suits.

The number of possible straight = 4⁵ × 10

= 10240

Thus, the probability to deal with a straight = \(\dfrac{10240}{^{52}C_5}\)

The probability to deal with a straight = \(\dfrac{10240}{\dfrac{52!}{5!(52-5)!} }\)

The probability to deal with a straight = \(\dfrac{10240}{\dfrac{52!}{5!(47)!} }\)

The probability to deal with a straight = \(\dfrac{10240}{2598960}\)

The probability to deal with a straight = 0.00394

Raising the minimum wage has the potential to reduce poverty, boost economic growth, reduce income inequality, and provide fair compensation for low-wage workers.

According to a report by the National Bureau of Economic Research, increasing the minimum wage has a significant effect on reducing poverty rates among low-wage workers. A higher minimum wage would allow low-wage workers to better meet their basic needs, such as housing, food, and healthcare.

A higher minimum wage can boost consumer spending, which in turn can drive economic growth. The Economic Policy Institute estimates that raising the minimum wage to $15 per hour would increase the pay of nearly 32 million workers and generate over $107 billion in additional wages.

The correct statement is that for each hour, the earnings go up by $7. Option A

If we have the equation of the line, we can substitute the value of 7 for the number of hours into the equation and solve for the earnings. The equation would typically be in the form of "earnings = slope * hours + y-intercept," where the slope represents the rate of earnings per hour and the y-intercept represents the earnings when no hours are worked.

We can find the slope of the graph to know as said above;

Answer:

a) 24

b) -21.

Step-by-step explanation:

For question a), we first solve whatever is in the parenthesis, because of PEMDAS.

Our original equation was:

4 (6 + (-3)) + 3 (4)

We get rid of the parenthesis first. 6 + (-3) = 6 - 3 = 3, so we have:

4 (3) + 3 (4)

We can multiply, and then add.

12 + 12 = 24.

For question b), we once again start off with getting rid of the parenthesis. However, within the parenthesis, we still have to follow PEMDAS, meaning that we have to do the multiplication first and the subtraction after.

Thus we have:

-2 (6) + 3(-3)

We can multiply things out and then add.

-12 + -9

= -1 (12 + 9)

= -1 (21)

= -21.

Answer:

cos2x=-17/145

Step-by-step explanation:

Recall cos2x=cos^2x-sin^2x

Or cos2x=cos^2x-(1-cos^2x)*

Or cos2x=2cos^2x-1**

*By a Pythagorean Identity

**Combined like terms

I'm going to use third identity from above because I only have to find cosx or cos^2x to get requested answer for cos2x.

Recall Pythagorean identity 1+tan^2x=sec^2x.

Plug in our tangent valuem...

1+(9/8)^2=sec^2x

1+81/64=sec^2x

145/64=sec^2x

Cosine and secant are reciprocals of each other.

64/145=cos^2x

Now we are ready to plug in and get final answer:

cos2x=2cos^2x-1

cos2x=2(64/145)-1

cos2x=128/145-1

cos2x=-17/145
