HELP PLEASE, I WILL MARK YOU AS BRAINLIEST​

Answer:

B) 378 students could be expected to attend the game.

Step-by-step explanation:

Out of 40 students, 45% agreed,

45% of 40

= 45/100 * 40

= 18 students,

18 students out of 40 agreed.

So, Out of 840 students 18/40 * 840 students would be expected to agree. We get :- 378

there are different ways of solving this:

one way is the follwing:

cos^2(x) -sin^2(x) =cos (2x)

then, equation becomes:

cos (2x) -sin (x)=0

but sin(x) is also equivalent to : cos ((pi/2)-x),

so, the equation now is:

cos (2x) - cos ((pi/2)-x)=0 -------> cos (2x) = cos ((pi/2)-x) ---------> 2x=(pi/2) -x

but since it is an angle, the answer would be repeating so:

2x= 2k(pi) +((pi/2)-x)

3x= pi( 2k+1/2)

x= (pi/3) (2k+1/2)

for k=0, x= pi/6

for k=1, x= 5pi/6

for k=2, x= 3pi/2

Whats the length and the width so I know what to multiply?
Because Area = L x W

Oh wait I think I just multiply them

19 x 20 = 380 x 25 = 9500

I think this is correct

If not im very sorry

Answer:

2

Step-by-step explanation:

(10 - 0)/(6 - 1) = 2

Answer:

All of them have intersections with each other, so we can't really say anything from that. But only -3x + 10 has a y-intercept higher than y=0.

So let's just say -3x+10 is different.

The positive values of M and N are; 3.6 and 5.6 respectively.

When S is minimum, s can be equated to 0.

On this note, it follows that the resulting equations are;

From Substitution of M = 2 +N in the second equation; it follows that;

Hence, upon solving the quadratic equation;

Therefore, the positive value of N is; 5.6 and hence,

Step-by-step explanation:

Your basic future value formula is:

FV = PV (1+i) ^ n

Where:

FV = Future Value

PV = Present value = $1000

i = interest rate per period = 8/2 = 4% = 0.04

n = number of periods = 6 semi annual periods

Answer:

Step-by-step explanation:

It would be more obvious if it says z is a standard Normal variable and that the question is related to statistics.

From "Computing Probabilities Using the Cumulative Table" , the probability of z is less than 1.16, P(z<1.16) = 0.8770.

[tex]A=18unit^{2}[/tex]

Answer:

x = 10 cm

Step-by-step explanation:

The volume of a pyramid is [tex]V = \frac{Bh}{3}[/tex], where V = volume, B = area of base, and h = height.

Step 1: Multiply both sides by 3.

Step 2: Divide both sides by 84.

Step 3: Check if solution is correct.

Therefore, x = 10 cm.

Answer:

2/5

Answer:

2/5

Step-by-step explanation:

The original answer was 4/10, but as a reduced fraction, it is 2/5.

Version of how I got it:

5 and 2 have 10 in common, so that is the denominator

1 and 1 have 1 in common. Keep change and flip, to turn this into a 4. this rule applies because 1 + 1 = 2, and 2 x 2 = 4.

finally...

4/10 -- 2/5

Reflect Over X-Axis Formula

The following formula is used to reflect a coordinate point about the x-axis.

(X2,Y2) = (X1,Y1) * (1,-1)

Where X2 and Y2 are the new reflected coordinates

X1 and Y1 are the original coordinate points

Reflect Over X-Axis Definition

Reflection over the x-axis is the process of producing a coordinate point that is mirrored across the x-axis of the coordinate plane. That is it has the same X coordinate and opposite y4 coordinate.

Reflect over X-Axis Example

How to reflect over the x-axis?

First, determine the original coordinate points.

For this example, we will say the coordinate points are (4,5).

Next, calculate the new coordinate points.

Using the formula above we calculate the new reflected points as (4,5)*(1,-1) = (4,-5).

Answer:

1.74 million (1,740,000)

Step-by-step explanation:

First we have to find 16% of 1.5 million

0.16 x 1,500,000 = 240,000

Now we add this to the original 1.5m

1,500,000 + 240,000 = 1,740,000

There is roughly 1.74 million in the population of Nairobi

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

Add 7 to both sides.

[tex]2x < 5+7[/tex]

Add 5 and 7 to get 12.

[tex]2x < 12[/tex]

Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.

[tex]x < \frac{12}{2}[/tex]

Divide 12 by 2 to get 6.

[tex]x < 6[/tex]
