The normal distribution can well approximate the binomial distribution as long as.
The normal approximation to the binomial is when you use a continuous distribution (the normal distribution) to approximate a discrete distribution (the binomial distribution).
consider the distance equation d=rt, where d is the distance (in feet), r is the rate (in feet per second), and t is the time (in seconds). you run fir 50 seconds. Are the distance you run and the rate you run at proportional? Use a graph to justify your answer.
Answer:
yes, they are proportional
Step-by-step explanation:
A proportion is a relation that can be modeled by a straight line through the origin. The equation will have the form ...
y = kx
where x is the independent variable, y is the dependent variable, and k is a constant of proportionality.
__
If you start with the equation relating distance, rate, and time:
d = rt
and you fix the time at 50 seconds, then the equation becomes ...
d = 50t
This is the equation of a proportion with a constant of proportionality of 50. It tells you the distance run is proportional to the rate you run. When this equation is graphed, it is a straight line through the origin.
What is the slope of the line that passes through the points (0,-10) and (-4,-11)? Write your answer in simplest form.
The slope of the line that passes through the points (0,-10) and (-4,-11) will be 1/4.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other. The more the slope is, the more the line is vertical. When slope is zero, the line is horizontal.
Its slope would be:
[tex]m = \dfrac{y-q}{x-p}[/tex]
Given that the line passes through the points (0,-10) and (-4,-11).
From the formula to find the slope of a line which passes through points
m= y2-y1 / x2-x1
Substitue the points (0,-10) and (-4,-11).
The slope = m = -11-(-10) /. -4-0
m = -1/-4
m = 1/4
Therefore, the slope of the line that passes through the points (0,-10) and (-4,-11) will be 1/4.

The following hemisphere has a radius of 8cm.
Find the volume of the hemisphere correct to 1 decimal place.
Volume of a sphere= 4/3 π r3
Pls help! I'm Stuck
Answer:
1072.3 cm³ (1 dp)
Step-by-step explanation:
A hemisphere is half a sphere.
Therefore, calculate the volume of a sphere with radius 8 cm, then half it.
Volume of a sphere = 4/3 π 8³
= 4/3 × π × 512
= 2048/3 π cm³
Volume of hemisphere = (2048/3 π) ÷ 2
= 1024/3 π
= 1072.3 cm³ (1 dp)
Sipho and Litha are brothers. The sum of their ages is 29. In 6 years' time Sipho will be the same age as Litha was 3 years ago. Determine the current age of the two brothers. Let x be the age of Sipho. 0 Copy and complete the table below: Current 3 Years Ago In 6 Years Sipho Litha Write down an appropriate equation in order to determine x. Solve for x and write down the age of Sipho and Litha
Answer: See below
Step-by-step explanation:
Let s represent Sipho's age and let l represent Litha's age
The sum of their ages is 29 years
s + l = 29...(1)
In 6 years time, Sipho (s+6), will be the same age Litha was 3 years ago (l-3)
(s+6) = (l-3)...(2)
Age:
s + l = 29
s = 29 - d (express c in d)
(29-s+6) = s - 3 (substitute c)
s+(29-s+6) = s+(d-3)
29+6 = 2s -3
29+6+3 = 2s
38 = 2s
19 = s
Back to (1):
l = 29 - 19
l = 10
Therefore, Sipho is currently 19 years old and Litha is 10 years old
The current age for the two brothers, Sipho and Litha is 10 years old and 19 years old respectively.
What is linear equation?A linear equation is the equation in which the highest power of the unknown variable is one.
To solve this problem, let's make the linear equations by the given statement.
Let x be the age of Sipho and y is the age of Litha. The sum of their ages is 29. Therefore,
[tex]x+y=29\\y=29-x[/tex]
Thus, the age of Litha is (29-x)
In 6 years' time, Sipho will be the same age as Litha was 3 years ago. Therefore,
[tex]x+6=(29-x)-3\\x+6=29-x-3\\x+x=29-3-6\\2x=20\\x=\dfrac{20}{2}\\x=10[/tex]
Thus, the age of Sipho is 10 years. The age of Litha is,
[tex]y=29-10\\y=19[/tex]
Hence, the current age for the two brothers, Sipho and Litha is 10 years old and 19 years old respectively.

In Cincinnati, fireworks are launched from a large barge on the Ohio River for a Labor Day celebration.
Their flight can be modeled by the function h(t) = -4.9(t - 4)2 + 80, where h is the height in meters and t is the time in seconds.
Suppose that buildings obstruct the fireworks. So, the barge is relocated 30 meters to the east.
Write a function to model the path of the fireworks in the new location.
The function to model the path of the fireworks in the new location is -4.9(t - 4)^2 + 50
Equations and expressionGiven the height reached by the flight expressed as:
h(t) = -4.9(t - 4)^2 + 80
If the barge is relocated 30 meters to the east, the new function will be derived by subtracting 30 from the initial function
New function = -4.9(t - 4)^2 + 80 - 30
New function = -4.9(t - 4)^2 + 50
Hence the function to model the path of the fireworks in the new location is -4.9(t - 4)^2 + 50

the zoo has 400 employess 72 percent of them are part time employess how many employess work full-time
Answer:
112
Step-by-step explanation:
There are 400 employees. If 72 of them work part-time, then 72% of 400 = 400*72%. This equals 288. Then you subtract that from 400 because the rest of them should be full-time workers. 400-288=112.
Answer:
112
Step-by-step explanation:
400 x 0.72 = 288, so that's the number of part-time employees.
400 - 288 = 112

x + 270 = 360
Subtract 270 from both sides of the equation
x + 270 - 270 = 360 - 270
Simplify
x = 90
Missing angle = 90

if your doing a stem and leaf plot with decimals and whole numbers, would the decimals be greater than or less than the whole numbers?
(will mark brainliest if you answer)
Let's say we had this data set
1212.71313.113.51414.9This is a collection of whole numbers and decimal values. We need to standardize everything so every value is the same length exactly. Something like "12" involves 2 digits while "12.7" involves 3 digits. We can rewrite 12 into 12.0 to standardize everything to 3 digits. Same goes for 13 into 13.0 and 14 into 14.0
This is the new updated list
12.012.713.013.113.514.014.9Everything now has a decimal point and involves exactly 3 digits.
From here, we'll form the stems: 12, 13, 14
The leaf values are the last digit. Each separate leaf digit refers to one exact number from the original data set.
Refer to the stem-and-leaf plot below.
As you can see, something like 13.0 is smaller than 13.1; therefore, the whole numbers are smaller than the decimal values for a given stem only.

Here's a question :-
1) The radii of the ends of a frustum of a cone 45cm high are 28cm and 7cm ( see figure ) . Find it's volume , the curved surface area ( Take π = 22/7 ) .
________________________________
♦ Note :-

✓ Quality answer needed ...
Answer:
volume: 49280 cm³ and curved S.A = 5826.64 cm²
Explanation:
height of smaller cone: h₂radius of smaller cone: 7height of bigger cone: 45 + h₂radius of bigger cone: 28using similarities:
[tex]\sf \frac{45 + h2}{28} = \frac{h2}{7}[/tex]
[tex]\sf 315 + 7h2 = 28h2[/tex]
[tex]\sf 315 = 28h2-7h2[/tex]
[tex]\sf 315 = 21h2[/tex]
[tex]\sf 15 = h2[/tex]
total height of the cone: 45 + 15 = 60 cm
solve for volume:
[tex]\sf volume \ of \ cone \ = \frac{1}{3} \pi r^2 h[/tex]
[tex]\sf volume \ of \ cone \ = \frac{1}{3} \pi (28)^2 (60)[/tex]
[tex]\sf volume \ of \ cone \ = 15680\ *\frac{22}{7}[/tex]
[tex]\sf volume \ of \ cone \ = 49280 \ cm^3[/tex]
First find the slant height using Pythagoras theorem -
[tex]\sf l^2 = r^2 + h^2[/tex]
[tex]\sf l =\sqrt{ r^2 + h^2}[/tex]
[tex]\sf l =\sqrt{ (28)^2 + (60)^2}[/tex]
[tex]\sf l =66.212 \ cm[/tex]
solve for curved surface area:
[tex]\sf curved \ surface \ area = \pi rl[/tex]
[tex]\sf curved \ surface \ area = \pi (28)(66.2)[/tex]
[tex]\sf curved \ surface \ area =5826.64 \ cm^2[/tex]
