Hannah has a chicken coop with six hens. Let X represent the total number of eggs the hens lay on a random day. The distribution for X is given in the table.
A 2-column table with 7 rows. Column 1 is labeled number of eggs with entries 0, 1, 2, 3, 4, 5, 6. Column 2 is labeled probability with entries 0.02, 0.03, 0.07, 0.12, 0.30, 0.28, 0.18.
What is the probability that the hens lay more than two eggs?
0.07
0.12
0.88
0.95
The probability that the hens lay more than two eggs is 0.80
How to determine the probability?The probability that the hens lay more than two eggs is calculated using:
P(x > 2) = P(3) + P(4) + P(5) + P(6)
Using the data on the table, we have:
P(x > 2) = 0.12 + 0.30 + 0.2 +, 0.18.
Evaluate the sum
P(x > 2) = 0.80
Hence, the probability that the hens lay more than two eggs is 0.80

Find the value of x in the parallelogram below
Answer:
102° is the value of x
Step-by-step explanation:
A = 78°
B = x
C = 78°
D = x
All angles of parallelogram = 360°
→ A + B + C + D = 360°
→ 78° + x + 78° + x = 360°
→ 156 °+ 2x = 360°
→ 2x = 360° - 156°
→ x = 204/2
→ [ x = 102° ]
Hence, the value of x is 102°.
2/3 of a class are girls.
A) what is the ratio girls to boys in the class?
B) what is the ratio boys to girls in the class
Ratio of girls to boys is 2:1
Ratio of boys to girls is 1:2
==========================================================
Explanation:
2/3 of the class are girls. If the class had 3 people, then 2 of them are girls. The remaining 3-2 = 1 person is a boy.
The ratio of girls to boys has us list the number of girls (2) followed by the number of boys (1). Separate the values with a colon. That's how we end up with 2:1
The ratio of boys to girls will have us flip that previous ratio to get 1:2
The order is important when it comes to forming ratios.

The patterns shown by the erosion data measurements is that Western Beach is losing sand while Dunes beach is gaining sand.
What is erosion?It should be noted that erosion simply means the washing away of the top soil.
In this case, the patterns shown by the erosion data measurements is that Western Beach is losing sand while Dunes beach is gaining sand.
The years when the beaches have approximately the same width will be between 11 and 12 years.
Assuming these rates remain constant, to get a better approximation of when the two beaches will have the same width, one can plot the data against time and draw a curve that goes through the data.

Consider the quadratic inequality, x^2 - 3x < 10. When you solve the inequality the solution is -2
Answer:
−2<x<5
Step-by-step explanation:
x2−3x=10
x2−3x−10=10−10(Subtract 10 from both sides)
x2−3x−10=0
(x+2)(x−5)=0(Factor left side of equation)
x+2=0 or x−5=0(Set factors equal to 0)
x=−2 or x=5
Check values in the intervals to see if they work.
x<−2(Doesn't work in original inequality)
−2<x<5(Works in original inequality)
x>5(Doesn't work in original inequality)
So, the proper answer for me is −2<x<5.

The annual commissions per salesperson employed by a retailer of mobile communication devices are normally distributed, and averaged $40,000, with a standard deviation of $5,000. what percent of the salespersons earn between $32,000 and $42,000?
Using the normal distribution, it is found that 60.06% of the salespersons earn between $32,000 and $42,000.
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 = 40000, \sigma = 5000[/tex]
The proportion of salespersons that earn between $32,000 and $42,000 is the p-value of Z when X = 42000 subtracted by the p-value of Z when X = 32000, hence:
X = 42000:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{42000 - 40000}{5000}[/tex]
Z = 0.4
Z = 0.4 has a p-value of 0.6554.
X = 32000:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{32000 - 40000}{5000}[/tex]
Z = -1.6
Z = -1.6 has a p-value of 0.0548.
0.6554 - 0.0548 = 0.6006 = 60.06%.
60.06% of the salespersons earn between $32,000 and $42,000.

The region r is enclosed by the curves y=4-4x2 and y=0
The region r is enclosed by the curves y₁ = 4 - 4x² and y₂ = 0 is 16/3 or 5.333 square units.
What is an area bounded by the curve?When the two curves intersect then they bound the region is known as the area bounded by the curve.
The region r is enclosed by the curves y₁ = 4 - 4x² and y₂ = 0
The intersection points will be
y₁ = y₂
4 - 4x² = 0
x = ±1
Then the area bounded by the curves will be
[tex]\rm Area = \int _{-1}^1 (y_1- y_2) dx\\\\Area = \int _{-1}^1 (4 - 4x^2) dx\\\\Area = \left [ 4x - \dfrac{4x^3}{3} \right ]_{-1}^1\\\\Area = 4 \left ( 1 + 1 \right ) - \dfrac{4}{3} \left ( 1^3 - (-1)^3 \right )\\\\Area = 8 - \dfrac{8}{3}\\\\Area = \dfrac{16}{3} = 5.333 \[/tex]

What inequality does the number line show
x>3
Inequalities with one variable are plotted on a number line, with the output representing the solution to the inequality. A number line is used to graph a linear inequality with only one variable. Two-dimensional graphs plot linear inequalities with two variables because the output gives the solution to both variables.
Answer:
x>3
Step-by-step explanation:
on a number line, an open circle indicates that the given value (3) isnt included and you would use < or >. a closed (filled in) means that the given value is included and u would use ≤ or ≥. the direction of the arrow (left of right) indicates if the values will be greater than or less than the value indicated by the circle (3). Here, the arrow is pointing right meaning that the values are getting larger until infinity starting at 3 (3 isnt included because of the open circle)

Step-by-step explanation:
a pie chart is a circle with differently sized pizza slices designating how many or how much in every category in relation to the whole (the full circle).
a full circle = 360°.
the listed teachers together have obviously 200 students.
that means 200 is the whole, and correlates to 360° (everything takes the whole circle).
20 students for Michelle means then 20 of 200 :
20/200 = 1/10 = 360/10 = 36°
38 students for Rose Grace.
38/200 = 19/100 = 19×360/100 = 0.19 × 360 = 68.4°
28 students for Melanie.
28/200 = 7/50 = 7×360/50 = 7×36/5 = 50.4°
36 students for Joy.
36/200 = 9/50 = 9×360/50 = 9×36/5 = 64.8°
42 students for Josephine.
42/200 = 21/100 = 21×360/100 = 21×36/10 = 75.6°
36 students for Daisy.
36/200 = 9/50 = 9×360/50 = 9×36/5 = 64.8°
you need to draw a circle with the sectors having the listed degrees. of course, you round to the nearest full degree.
if done right, these sectors fill the whole circle.
Suppose you leave your house and travel 13 mi due west. then you travel 3 mi due south. how far are you from your house?
13.34 mi
from question,
perpendicular (p) = 3mi
base(b) = 13 mi
hypotenuse (h) = ?
from Pythagoras theorem,
h^2 = p^2 + b^2
h = √(3^2 + 13^2)
h = √(9+169)
h= √(178)
h= 13.34 mi
Answer:
≈ 13.3 miles
Step-by-step explanation:
a line due west and a line due south form a right triangle with the hypotenuse being the direct distance x from the house.
using Pythagoras' identity in the right triangle , then
x² = 13² + 3² = 169 + 9 = 178 ( take square root of both sides )
x = [tex]\sqrt{178}[/tex] ≈ 13.3
distance from house ≈ 13.3 miles ( to the nearest tenth )

Answer:
3/4 shall be our slope.
Step-by-step explanation:
You can solve the slope by doing this formula y₂ - y₁ / x₂ - x₁ = slope.
Your coordinates:
(-4,0) and (0,3)
You have to set up your formula:
3 is the y2 and 0 is the y1
3-0 for y so far.
Now, set up the x's
0 is our x2 more known as our second x
Then our x1 is -4
0 - (-4).
Our Formula:
3-0 / 0+4
**Notice the negatives canceled to a positive due to the rule.**
3/4 shall be our slope.
You could've also risen and run starting from (-4,0) to (0,3) to get a slope of 3/4.
