17% of students in a class have brown hair. If 6 students are chosen at random, what is the probability that exactly 3 have brown hair? (Write your answer as a percentage rounded to the nearest tenth.)
Answer:
6.8%
Step-by-step explanation:
the question has no information about class size (no. of student in class)
assume no. of student is infinite
P(3brown out of 6) = 6C3 * P(brown)^3 * P(not brown)^3
= 20 * 0.004913 * 0.695789
= 0.06837
Chiletso just got a new cylindrical fish tank, which he plans to stock with a variety of african cichlids.
. the height of the cylindrical fish tank is 30 inshes.
. the length of the diameter of the base is 27.5 inches.
. one us gallon is equal to approximately 231 cubic inches.
. cichlids grow to approximately 6 inches.
. a good rule of thumb is to have about 3 inches of fish per 2 gallons of water.
calculate the maximum number of african cichlids chiletso can put in his tank.
The maximum number of African cichlids which can put by Chiletso in this cylindrical fish tank is 19.
What is of volume of cylinder?Volume of cylinder is the amount of quantity, which is obtained by it in the 3 dimensional space.
The volume of the cylinder can be given as,
V=(πd^2h)4
Here, (d) is the diameter of the base of the cylinder and (h) is the height of the cylinder.
The height of tank is 30 inches and the length of the diameter of the base is 27.5 inches. Thus, the volume of it is,
V=[π(27.5)²(30)] /4
V=17818.72 cubic inches.
One us gallon is equal to approximately 231 cubic inches. Thus, the volume in gallon is,
V=17818.72/231
V=77.12 gallons.
A good rule of thumb is to have about 3 inches of fish per 2 gallons of water. The number of 6 inches cichlids the can put in 77.12 gallons tank is,
V=(77.12 x 3)/(6 x 2)
V=19.28
Thus, the maximum number of African cichlids which can put by Chiletso in this cylindrical fish tank is 19.

1. i dentify if the following figure is an examle of a parallelogram. show your solution.
2. is this given figure on the side a parallelogram of Not?(prove using the properties of parallelogram)
The value of the x and y is 12 and -10 respectively, and the provided figure is a parallelogram because the diagonals bisect each other.
What is parallelogram?In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
As we know in the parallelogram, the diagonals bisect each other.
Then,
432 = 3x²
x² = 144
x = √144
x = 12
In the parallelogram, the adjacent opposite angles are the same.
∠C+∠B = 240°
= 360 - 240
∠A + ∠D = 120°
∠A = ∠D = 120°/2 = 60
∠D/2 = 60/2 = 3y + 60
3y + 60 = 30
3y = -30
y = -10
From the definition of the parallelogram, the provided figure is a parallelogram.
Thus, the value of the x and y is 12 and -10 respectively and the provided figure is a parallelogram because the diagonals bisect each other.

A particular tree falls over in a bonsai forest and is considered to be an average tree (in the middle 20%). If the mean height is 10cm and the standard deviation is 2 between what heights must the tree be?
Using the normal distribution, it is found that the tree must have heights between 9.49 cm and 10.51 cm.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 10, \sigma = 2[/tex]
Considering the symmetry of the normal distribution, the middle 20% is between the 40th percentile(Z = -0.253) and the 60th percentile(Z = 0.253), hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.253 = \frac{X - 10}{2}[/tex]
X - 10 = -0.253 x 2
X = 9.49.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.253 = \frac{X - 10}{2}[/tex]
X - 10 = 0.253 x 2
X = 10.51.

302.1 in a fraction form
Answer:
302 1/10 is our fraction form more known to be a mixed number.
Step-by-step explanation:
Fraction form from decimal is to keep our 302 and make .1 a fraction.
This is because we already have a base/whole number and just need a fraction to make this decimal an improper fraction. 0.1 is equivalent to 1/10 because in order to get to 0.1 you need to move the decimal point 1 digit to the right. You could also do 1 divided by 10.
302 1/10 is our fraction form more known to be a mixed number.
Question, if 1 = 10, 2 = 12, 3 = 14, and 4 = 16, what would 5 equal?
Answer:
5=18
Step-by-step explanation:
they are counting by 2s 10,12,14,16,18
Hope this helps!
Answer:
18
Step-by-step explanation:
It seems like for this pattern, as the x-value(base value) increases, the corresponding y-value(value changing with the base value) increases by 2 given that the function starts with a y-intercept of 8. So at the value 0, the corresponding number would be 8. So in this case, by creating a function regrading this information we can solve for the corresoponding value of 5: y = 2x + 8
y = 2 * 5 + 8
y = 10 + 8
y = 18
5 = 18
Another way to approach this is just by following the pattern given to us in the description. We see that the pattern starts at 10, and increases by 2 for each increasing base value. Therefore, if 4 = 16, then 16 + 2 = 5, so 5 = 18.

E

(not drawn to scale)
A 1
B 11

The length of the segment DF is 11 units
How to determine the length of DF?The given parameters are:
ED = 2y + 12
DF = 3y + 8
EF = 25
The length EF is:
EF =ED + DF
This gives
2y + 12 + 3y + 8 = 25
Evaluate the like terms
5y + 20 = 25
Subtract 20 from both sides
5y = 5
Divide by 5
y = 1
Substitute y = 1 in DF = 3y + 8
DF = 3(1) + 8

Answer:
D. It takes them more time to deliver packages because 157.3 x 1.25 = 196.625
Step-by-step explanation:
In the question, it states that this week it took the delivery drivers 1.25 times longer to deliver packages than last week, meaning that it took more time to deliver the packages this week than last week. With this, we can eliminate choices A and C.
Because it took them 1.25 times longer, then we can multiply 157.3 by 1.25 to find the correct sum.
157.3 × 1.25 = 196.625
The only answer choice that matches this information completely is choice D, so that is the answer.

B. (1, -6)
C. (3, 0)
D. (6, 1)
Answer:
(-2,15) (3,0)
Step-by-step explanation:
By substituting the x value in the coordinate (the first number in the bracket) and solving the equation, you must get the y value in the coordinate (second number in the bracket.
So that is to say:
A
y= -3x + 9
y = -3(-2) + 9
y = 6 + 9
y= 15
Also note that B is not one of them, because the y value you get when you substitute the x value in the equation is NOT NEGATIVE 6.
