Answer:

B.-7/25

Step-by-step explanation:

edge

The required value of cos(2x) is -7/25. Option B is correct.

sinx = 4/5
cosx < 0

Trigonometry is the study of angles in mathematics.

Here,
cos(2x) = 1-2sin²x
           = 1 - 2 x 4²/5²
           =  1 - 32/25
cos(2x) =  -7/25

Thus, the required value of cos(2x) is -7/25.

Question:

Which interest rate is missing from Renee’s table?

Answer:

Principal- $750

Interest Rate- $00.5

Time- 11 yrs. (Years)

Interest- $412.50

Explanation:

To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate. ...

I = Interest amount paid in a specific time period (month, year etc.)

P = Principle amount (the money before interest)

t = Time period involved.

r = Interest rate in decimal.

Therefore we get an answer of $00.5

Answer: 8m

Step-by-step explanation:

5+1+2=8

Answer:

7m + m

Step-by-step explanation:

If you combine like terms, your final answer would be 8m. However, you said you wanted an expression so 7m + m would be an equivalent one. 8m is a term, not an expression.

Answer:

m = 4/3

Step-by-step explanation:

Slope of line is given by

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

where

(x1,y1) and (x2,y2) are the two points on coordinate plane.

__________________________________________

Given points

(4,5) and (7,9)

using the above formula to find slope and plugging in the given points value

we have,

slope m = (9-5)/(7-4)

m = 4/3

Thus, slope between the points (4,5) and (7,9) is m = 4/3. The third option.

Answer:

-9 pounds / month

Step-by-step explanation:

A loss of 36 pounds is a negative number

-36

Divide by the number of months

-36 pounds / 4 months

-9 pounds / month

Divide total loss by number of months:

36 pounds / 4 months = 9 pounds per month.

Because it lost weight the integer would be negative 9 (-9)

Answer:

125

Step-by-step explanation:

The college administrators captured the 90 fraternity men and tagged them, then they returned them to the university campus.

Let there were x tagged fraternity men already on the university campus, so, the total number of tagged fraternity men on the campus become x+90.

Later a group of sorority women captured 215 tagged men, in which the 90 tagged men added by the college administration are included.

So, x+90=215

[tex]\Rightarrow x=215-90=125.[/tex]

Hence, the number of fraternity men on the campus was 125.

Answer:

0.121

Step-by-step explanation:

From the given information:

Let X be a hypergeometric random variable. i.e X [tex]\sim[/tex] h (x;:6,7,12)

To determine the mean and the standard deviation of X of a hypergeometric random variable; we have:

[tex]\mu_x = E(X)[/tex]

[tex]\mu_x = 6 \times \dfrac{7}{12}[/tex]

[tex]\mu_x =1 \times \dfrac{7}{2}[/tex]

[tex]\mu_x =3.5[/tex]

The standard deviation is :

[tex]\sigma _x = \sqrt{(\dfrac{12-6}{12-1}) \times 6 \times (\dfrac{7}{12})\times (1-\dfrac{7}{12})}[/tex]

[tex]\sigma _x = \sqrt{(\dfrac{6}{11}) \times 6 \times (\dfrac{7}{12})\times (\dfrac{5}{12})}[/tex]

[tex]\sigma _x = \sqrt{\dfrac{35}{44}}[/tex]

[tex]\sigma _x = 0.892[/tex]

However, the inequality for the event showcasing how X exceeds its mean value by more than 1 standard deviation is :

[tex]X \geq \mu_x +\sigma_x[/tex]

[tex]X \geq 3.5 +0.892[/tex]

[tex]X \geq 4.392[/tex]

[tex]X \geq 5[/tex]

∴

[tex]P(X \geq \mu_x + \sigma_x ) = P(X \geq 5)[/tex]

[tex]P(X \geq \mu_x + \sigma_x ) = 0.121[/tex]

Answer:

No.

Step-by-step explanation:

We will figure this out using subtraction.

96-24=72

112-28= 84

Simplified:

72/9= 8

84/9=9.33

So, no. They are not equivalent. Also is there any context?

Answer:

[tex]September = 2697[/tex]

Step-by-step explanation:

Given

[tex]June = 1,898[/tex]

[tex]July = 2,643[/tex]

[tex]August = 2,287[/tex]

[tex]Expected = 9,525[/tex]

Required

Number of cans in September

First, we need to determine the total collected can from July to August.

[tex]Total = 1898 + 2643 + 2287[/tex]

[tex]Total = 6828[/tex]

September is then calculated as follows:

[tex]September = 9525 - 6828[/tex]

[tex]September = 2697[/tex]

Hence:

2697 cans are still needed
