4.) Dylan scored a 95, 78 and 89 on his first three science tests. Write and solve an inequality to determine what is the lowest possible score he can get on his fourth test to average at least a 90 in the class.
Answer:
98
Step-by-step explanation:
Dylan must get at least a 98% to reach an average of 90. (95+78+89+98)÷4=90.

The circle with center C was used as a model for a hot tub. The length of is 2 m. What is the circumference of the hot tub?
Answer:
6.283 m
Step-by-step explanation:
2m is the length so half is the radius
the radius is 1
so if c=2[tex]\pi[/tex]1
and [tex]\pi[/tex] 3.14159
u get 6.283

Water flows back and forth between a small and large tank. When water is moving into a tank the flow rate is positive, and when water is moving from a tank the flow rate is negative. The large tank begins with 300 gallons of water, and the small tank begins with 200 gallons of water. After a period of 5 minutes, the large tank has the same amount of water as the small tank. Which statement describes the flow rate?

When Grayson moved into a new house, he planted two trees in his backyard. At the time of planting, Tree A was 29 inches tall and Tree B was 14 inches tall. Each year thereafter, Tree A grew by 2 inches per year and Tree B grew by 5 inches per year. Let A A represent the height of Tree A t t years after being planted and let B B represent the height of Tree B t t years after being planted. Write an equation for each situation, in terms of t , t, and determine the height of both trees at the time when they have an equal height.

Answer:
9.) I 5/14 * 4/13 10.) H 45
Step-by-step explanation:
For 9.) the probability the first time to get a red marble is 5/14 because there are 5 red marbles and 14 total marbles. The probability the second time she picks, if a green one was chosen, one is 4/13 because one green marble needs to be missing and because one marble is missing 14-1=13 so there are 13 total marbles. You would multiply the two probability (5/14 and 4/13) to find the probability of drawing two green marbles in a row
For 10.) I found that 2/5= .4 and 5/8= .625 so I multiplied both fractions by 200
.4 * 200= 80
.625 * 200= 125
These are the numbers of games both people won
Subtract the two and you get 125-80= 45 which is how many more games Tyrell would win.
What is the measure of each angle in a hexagon if the lengths of all six sides are equal?
solve for x 2x+5=17 plzhelp
x = 6
you have to work out the problem and what ever you do to one side, you do to the other
Answer:
x=6
Step-by-step explanation:
2x+5=17
Subtract 5 from both sides;
2x+5-5=17-5
Simplify
2x=12
Divide both sides by 2;
2x/2=12/2
Simplify;
x=6

Slope=5, goes through the point (2,7)..
Answer:
the y-intercept is 7
Step-by-step explanation:
hope it helps. i just looked at the ordered pair and took the number that's on the y axis
Answer:
y=5x-3
Step-by-step explanation:
Slope intercept form is y=mx+b and you know the slope so you can get y=5x+b
Then you are given a point, (2, 7), so you can plug that into the equation to find the y-intercept
7=5(2)+b
Then you just solve for b
7=10+b
-10
-3=b
So the final equation is y=5x-3
The American Civil War (also known by other names) was a civil war in the United States from 1861 to 1865, fought between northern states loyal to the Union and southern states that had seceded to form the Confederate States of America. The principal cause of the war was the status of slavery in the United States, especially in the territories. After Abraham Lincoln won the November 1860 presidential election on an anti-slavery platform, an initial seven slave states declared their secession from the country to form the Confederacy. War broke out in April 1861 when secessionist forces attacked Fort Sumter in South Carolina, just over a month after Lincoln's inauguration. An additional four slave states joined the Confederacy in the following two months. The Confederacy grew to control at least a majority of territory in those eleven states (out of the 34 U.S. states in February 1861), and it claimed the additional states of Kentucky and Missouri by assertions from native secessionists fleeing Union authority. These states were given full representation in the Confederate Congress throughout the Civil War. The two remaining slave states, Delaware and Maryland, were invited to join the Confederacy, but Delaware declined and nothing substantial developed in Maryland due to intervention by federal troops. The Confederate states were never diplomatically recognized as a joint entity by the government of the United States, nor by that of any foreign country. The states that remained loyal to the U.S. were known as the Union. The Union and the Confederacy quickly raised volunteer and conscription armies that fought mostly in the South for four years. Intense combat left between 620,000 and 750,000 soldiers dead, along with an undetermined number of civilians. The Civil War remains the deadliest military conflict in American history, and accounted for more American military deaths than all other wars combined until the Vietnam War. The war effectively ended on April 9, 1865, when Confederate General Robert E. Lee surrendered to Union Ge…

The top of the Washington Monument is a triangular pyramid with a triangular base. Each triangular face is 24 feet high with a base that is 16 feet wide. The lateral faces of the pyramid are covered with white marble. About how many square feet of marble cover the lateral faces of the pyramid
Answer:
3944ft^2
Step-by-step explanation:
o 4 triangular faces of the pyramid will have total area
= 4 ×12 × base × height = 4 × 12 × 34 × 58ft^2 = 3944ft^2
So 3944ft^2 of marble cover the faces of the pyramid.

Answer:
2600, 3400, 5000, 7000
Step-by-step explanation:
This equation can be simplified to 200n + 1000. Now we can just plug in the amount of customers. 200 * 8 + 1000 = 2600. 200 * 12 + 1000 = 3400. 200 * 20 + 1000 = 5000, and 200 * 30 + 1000 = 7000.

Answer: 6.
Step-by-step explanation:
A data set has a mean of 7, a median of 5, and a mode of 8. Which of the numbers (7, 5, or 8) must be in the data set?
If possible, please explain in words, thank you. :)
given that there is one possible outlier. if the outlier was removed from the data set, how would it effect the measures of central tendency? {8, 73, 74, 75, 79, 85, 85, 92, 94}
(not links)
O Mean increases median decreases
O Mean decreases median increases
O Both mean and median increase
O Both mean and median decrease
Answer:
Some measures I believe you are talking about are mean, median, mode, and range.
Mean is the average of all values. This is found by adding up all numbers and dividing by the amount of numbers. Outliers greatly affect and "throw off" the mean, making it inaccurate at calculating the average without an outlier.
Example:
1, 2, 4, 6, 10
(1 + 2 + 4 + 6 + 10)/5 = mean = 4.6
1, 2, 4, 6
(1 + 2 + 4 + 6)/4 = mean = 3.25
Because of this, mean does change when adding and removing outliers, and is therefor not the answer.
Median is the middle of the data. This is found by ordering the values in the data set from least to greatest (or greatest to least, either one works) and finding the number in the center of all the values. If there were an outlier, the median wouldn't be skewed as the mean is by outliers, but it would change.
Example:
1, 2, 4, 6, 10 Median = 4
1, 2, 4, 6 Median = 3
So median is not the answer, because it is affected by adding and removing outliers.
Mode is the value in a data set that appears the most. Outliers are numbers that are significantly lower or higher than most or all of the other numbers in a data set. Because of this, there can't be more outliers than other numbers, so it is impossible for the mode to be an outlier.
Example:
1, 1, 1, 2, 3, 4, 4, 86 Mode = 1
1, 1, 1, 2, 3, 4, 4 Mode = 1
This means the mode is not affected by adding and removing outliers.
Mode is a possible answer, but let's take a look at range before coming to a conclusion.
Range is the spread of values in a data set. In other words, the difference between the highest and lowest value. A high range can signal a possible outlier is present.
Example:
1, 2, 4, 6, 10
10 - 1 = highest value - lowest value = range = 9
1, 2, 4, 6
6 - 1 = highest value - lowest value = range = 5
The range is certainly affected by outliers, so it is not the answer.
Out of mean, median, mode, and range, the answer to this question is mode.
If an outlier is removed, mode will not change.
Hope this helps!
