5th grade math. correct answer will be marked brainliest.

Answer:

I hope this helps <3

Step-by-step explanation:

What's the probability of getting heads on the second toss given that the first toss was a head. (Trying to refresh my probability a bit). I've seen this analyzed like this:

HH 1/4

HT 1/4

TH 1/4

TT 1/4

So since we are given information (Head on first flip), then TT goes away and were are left with:

HH 1/3

HT 1/3

TH 1/3

So we could say that HH now has a 1/3 probability. Should we not also get rid of TH, since we know that the first flip is a head? So now we have:

HH 1/2

HT 1/2

Its 1 1/5 :)

Answer:

Experimental Statistical Study

Step-by-step explanation:

Of the three types of statistical study, the one used by the researcher in this question is the experimental statistical study and the reason is as follows:

From the question, a study was conducted on a total of 4 high schools; these high schools were further divided into 2 pairs.

Each pair were subjected to or experimented with different method of teachings. At the end of the semester, the average were compared.

This implies that both pairs were experimented based on different teaching methods and the result of the methods were measured in order to determine which of the methods is better.

This type of study is experimental

Answer:

Experiment ; No, because the schools could be very different, meaning the randomization won't smooth out other effects.

Answer:

c is the answer

Step-by-step explanation:

Answer:

11 + c

Explanation:

In the parenthesis, 7 + c cannot be simplified, so there is no need for them. Now we have 7 + c + 4. Only 7 and 4 can be added. 7 + 4 = 11. The answer is 11 + c.

Answer:

c+11

Answer:

[tex]3; \frac{233}{27}[/tex].

Step-by-step explanation:

1) to calculate the discriminant of the given equation:

D=(314/2)²-699*27=5776.

2) to calculate the roots of the given equation:

[tex]\left[\begin{array}{ccc}y=\frac{157-\sqrt{5776} }{27} \\ y=\frac{157+\sqrt{5776} }{27} \end{array}[/tex]

[tex]<=> \ \left[\begin{array}{ccc}y=3\\y=\frac{233}{27} \end{array}[/tex]

Answer:

in feet its 19

In inches it would be 4

f(x) = x³ - 2x² - 24x

x³ - 2x² - 24x = 0

x(x² - 2x - 24) = 0

x = 0

x² - 2x - 24 = 0

a = 1, b = -2, c = -24

Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100

x = (-(-2) - 10)/(2 * 1) = -8/2 = -4

x = (-(-2) + 10)/(2 * 1) = 12/2 = 6

Answer: 2)

the ones with straight lines are functions the ones that are curved is not a function

Answer:

Ones that have 2 values of y for a single value of x

(vertical line, sideways v shape are not functions)

Step-by-step explanation:

In a function, each input (x) can have only one output (y)

There cannot be two ys for one x

Answer:

-629.88

Step-by-step explanation:

Total winnings/losses for 543 plays=Expected payoff ⋅ Number of plays=−$1.16⋅543=−$629.88

Answer:

54 degrees. The triangle is isosceles, so 180-72= 108.

108/2=54

The solution is,  m KJL=54 degrees.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

from the given figure, we get,

The triangle is isosceles,

so 180-72= 108.

and, we know,

∠J=∠L

So,

108/2=54

Hence, The solution is,  m KJL=54 degrees.

Answer:

The regular cost of each ticket is $30

Step-by-step explanation:

Hi,

You and three friends means there was a total of 4 people. Your equation is...

4x - 20 = 100

Remember to add the -20 since there was a coupon that saved you $20.

Now solve...

4x - 20 = 100

+ 20 on both sides

4x = 120

Divide by 4 on both sides

x = 30

The regular cost of each ticket is $30

Hope this helps :)

9514 1404 393

Answer:

  a.  see below for diagram. Angle for the length; length for the angle

  b. 6.84°; not to code

  c. 36.1 ft

Step-by-step explanation:

a. The diagram is shown below. Mr. Gow needs to find the angle it makes in order to determine if it is up to code. Alternatively, Mr. Gow needs to find the required length for a ramp that meets code.

__

b. The angle the ramp makes can be found using the tangent relation.

  Tan = Opposite/Adjacent

  tan(angle) = 3/25

  angle = arctan(3/25) ≈ 6.84°

The ramp will make a 6.84° angle with the ground. It will not meet code.

__

c. We can find the distance from the building where the ramp must start using the same trig relation.

  tan(4.75°) = (3 ft)/(distance)

  distance = (3 ft)/tan(4.75°) ≈ 36.1 ft

The ramp must start 36.1 feet from the building to exactly meet code.

ABOVE answer is absolutely correct

Answer:

  131.3°, 48.7°

Step-by-step explanation:

Let x represent the larger angle. Then x-82.6 is the smaller one. Their sum is ...

  x +(x -82.6) = 180

  2x = 262.6

  x = 131.3

  x -82.6 = 48.7

The two angle measures are 48.7° and 131.3°.

Answer:

The (x,y) point of the vertex is usually labelled as:

Vertex = (h, k)

h = -b / 2a

k = ah^2 + bh + c

f(x) = -3x^2 + 12x -5

a = -3 b=12 c=-5

h = -12 / -6  therefore h = 2

k = -3*2^2 + 12*2 -5

k = -12 + 24 -5  therefore k = 7

Vertex (2, 7)
