Number of Movies Watched per Month 10, 8, 4, 2, 6, 8, 9 What is the median of the data set
Answer:
8
Step-by-step explanation:
first you put the data in order :
2 , 4 , 6 , 8 , 8 , 9 , 10
then the middle number in the data is the median which in this case is 8 ( if you've got 2 middle numbers then you add both of them and divide by 2 )

which statement describes the effect on the parabola y= x^2 -1 when its is changed to y =x^2 +6?
The effect on the parabola y = x^2 - 1 when it is changed to y = x^2 + 6 is a translation of 7 units upwards.
What is the effect on the parabola?First let's do an introduction, for any function f(x), we can define a vertical translation of N units as:
g(x) =f(x) + N
Where if N > 0, the translation is upwards, and if N < 0, the translation is downwards.
In this case, we start with the parabola:
y = f(x) = x^2 - 1
Now we know that the transformed function is:
y = g(x) = x^2 + 6
Now, notice that if we apply a translation upwards of 7 units of the original function we will get:
y = f(x) = x^2 - 1 + 7 = x^2 + 6
We got the transformed function.
Then the effect on the parabola is a translation of 7 units upwards.

How long will it take you to double an amount of $500 if you invest it at a rate of 4% compounded monthly?
Answer:
Number of year = 17 year 4 month (Approx.)
Step-by-step explanation:
Given:
Current amount = $500
Future amount = 2 x 500 = $1,000
Rate of interest = 4%
Find:
Number of year
Computation:
Rate [Monthly] = 4% / 12 = 0.00333
Total time = 12 x n = 12n
A = P[1+r]¹²ⁿ
1000 = 500[1+0.003333]¹²ⁿ
2 = [1+0.003333]¹²ⁿ
2 = [1.003333]¹²ⁿ
Number of year = 17.358
Number of year = 17 year 4 month (Approx.)

Determine which of the two acute angles has a cosine of 4/5.
Answer:
CosA = 4/5
Step-by-step explanation:
The acute angle with cosine of 4/5
Recall from trigonometry ;
Cosine = Adjacent / hypotenus
From the right angled triangle Given:
For angle A :
Opposite = BC = 8
Hypotenus = AC = 10
Cos A = BC / AC = 8 /10 = 4 /5
CosA = 4/5
For C :
Opposite = AB = 6
Hypotenus = AC = 10
Cos C = 6 /10 = 3 /5
WHAT IS THE LENGTH OF AC? ROUND TO ONE DECIMAL PLACE. DONT HAVE TO SHOW WORK helpppp
Answer:
AC ≈ 5.5
Step-by-step explanation:
Angle bisector theorem states that "angle bisector of an angle divides the opposite side into two segments which are proportional to the other two sides of the triangle."
By applying this theorem in the given ΔABC,
AD is the angle bisector of ∠CAB which divides the opposite side of the angle into two segments BD and CD.
Therefore, [tex]\frac{AB}{BD}=\frac{AC}{CD}[/tex]
[tex]\frac{5.1}{4}=\frac{AC}{4.3}[/tex]
[tex]AC=\frac{5.1\times 4.3}{4}[/tex]
AC = 5.4825
AC ≈ 5.5 units

A. 0.09
B. 0.12

D. 0.35
Answer:

Step-by-step explanation:
The probability that a person consumes 2,000 to 2,500 calories in a day is 0.22.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Given that:
Weight/Calories 1000-1500 1500-2000 2000-2500 Total
per Day
120 lb. 90 80 10 180
145 lb. 35 143 25 203
165 lb. 15 27 75 117
Total 140 250 110 500
Hence, Total no. of person consumes 2000 to 2,500 calories in a day = 110
And, Total = 500
Now the probability that a person consumes 2,000 to 2,500 calories in a day :
⇒ 110 / 500
⇒ 0.22
Hence the probability that a person consumes 2,000 to 2,500 calories in a day is 0.22.

Which equation describes the circle
with center (5,-1) and radius 7?
A (x - 5)' + (y +1)* = 7

D(x + 5)' + (y - 1)' = 49
Answer:
B. (x-5)²+(y+1)² = 49
Step-by-step explanation:
An equation of a circle with center (h, k) and radius r is

Sixteen percent of videos are shorter than what
length?
The graph shows the distribution of the lengths (in
seconds) of videos on a popular video streaming site.
The distribution is approximately Normal, with a mean
of 264 seconds and a standard deviation of 75
seconds.
O 39 seconds
O 114 seconds
O 189 seconds
O 339 seconds
Streaming Videos
Answer:
189 seconds
Step-by-step explanation:
16% shorter,
Left side first and second group is 2.5% and 13.5% = 16%
189 is the max of that group
16% of videos on the streaming site are shorter than 189 seconds.
To determine the length at which 16% of videos are shorter, we can use the properties of a normal distribution.
Given that the mean length is 264 seconds and the standard deviation is 75 seconds, we can use a Z-score to find the corresponding percentile.
First, we need to find the Z-score associated with the 16th percentile. This can be done using a Z-table or a statistical calculator. The Z-score corresponding to the 16th percentile is approximately -0.9945.
Using the formula for Z-score:
Z = (X - μ) / σ,
where X is the length of the video, μ is the mean, and σ is the standard deviation, we can rearrange the formula to solve for X:
X = Z * σ + μ.
Substituting the values:
X = (-0.9945) * 75 + 264,
X ≈ 189 seconds.
Therefore, approximately 16% of videos on the streaming site are shorter than 189 seconds. So, the correct answer is 189 seconds.

Which choice correctly describes this event? Every time I flip a coin / will get tails.
A)Certain
B)Impossible
C)Likely
D)Unlikely
Please help ASAP ill give BRAINLIEST
Answer:
D
Step-by-step explanation:
With each flip of the coin, the chance of it landing on tails is multiplied by half. Hence the chance of landing a consecutive series of tails decreases the more times you flip the coin, but never reaches 0.
A is incorrect as it is possible to land heads on any flip.
B is incorrect as there is always a possibility of landing tails on every flip.
C is incorrect as the chance of getting tails on every flip is small (and gets smaller) and hence cannot be considered to be likely.
Hence D is the answer.
What two numbers equal 6 when multiplied but equal —7 when added?
Answer:
-1 , -6
Step-by-step explanation:
Let x be the first number and let y be the second number.
x * y = 6
x + y = -7
Let's first find the factor pairs of 6.
1, 6
2, 3
-1, -6
-2, -3
Now, we just need to take each factor pair and add them together and see which one equals -7.
1 + 6 = 7, so that is wrong.
2 + 3 - 5, so that is also wrong.
-1 - 6 = -7, so this is our answer (-2 and -3 added is -5, which is wrong).
Therefore, our answer is -6 and -1.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 12) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 12 = 36. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - thirty-two thirds plus one hundred nineteen twelfths = two hundred forty-seven twelfths.
