Answer:
a arithmetic; -23
Step-by-step explanation:
this is not geometric sequence as we don't see multiplication effect in the terms
let's see what is the difference in terms
-207- (-184)= -23
-230- (-207)= -23
-253- (-230)= -23
we can state it is an AP with common difference of -23
option a. is correct
how do i calculate the first quartile and the third quartile???
!!!please help!!!
Answer: The Median: 78, The First Quartile: 63, and The Third Quartile: 99
Step-by-step explanation: Ok, so let's put the data set from least to greatest....
(63, 63, 76,) (77, 79,) (84, 99, 99)
First Quartile Third Quartile
First, let's find the median, since you made a little mistake...
77 + 79 = 156
156 ÷ 2 = 78
The median is 78!
Now, let's determine the first quartile and the third quartile.
For the the first quartile/third quartile it'll be the middle number, if it's even we'll do the same extra step just like we'll do for the median. In this case it's not even therefore...
First Quartile: 63
Third Quartile: 99

Answer:
[tex]3\dfrac{5}{8}[/tex] pizzas.
Step-by-step explanation:
It is given that Aisha and her friends ate [tex]2\dfrac{1}{2}[/tex] pizzas.
After the party, the remaining pizza is [tex]1\dfrac{1}{8}[/tex] pizzas.
Now,
[tex]2\dfrac{1}{2}=\dfrac{4+1}{2}=\dfrac{5}{2}[/tex]
[tex]1\dfrac{1}{8}=\dfrac{8+1}{8}=\dfrac{9}{8}[/tex]
Pizzas at the starting = Pizza eaten by Aisha and her friends + Remaining pizza
[tex]=\dfrac{5}{2}+\dfrac{9}{8}[/tex]
[tex]=\dfrac{20+9}{8}[/tex]
[tex]=\dfrac{29}{8}[/tex]
[tex]=3\dfrac{5}{8}[/tex]
Therefore, [tex]3\dfrac{5}{8}[/tex] pizzas were there at the start of the party.

The last time Andy went bowling he had a mean score of 158
per game.
After three games Andy has a total score of 473. He thinks he
needs to score over 160 in game four to get a mean score
greater than 158.
(a) Is Andy correct?
Show why you think this.
Show a check of your working.
Your answer:
Answer:
no
Step-by-step explanation:
suppose he will get exactly the score of 160 in the game four, the mean score this time will be (473+160)/4=158.25
which has already reached the mean score 158 and even higher than it
therefore, his statement is wrong

The cost of renting a community center is $100, with and additional $10 per guest.
Which graph has the most appropriate scales and units for this situation? (pictures attached)
Answer:
I think it is A
Step-by-step explanation:
the reason i am saying A is that you don't really know how many guests are coming it could be 10 or 15 or even more.
Answer:
Ok so it is A, I'm almost positive because the first fee is 100 but if you add ten people it is two hundred. the price is DEPENDANT on the amount of people so people is the Independent variable or (x) and cost is the dependent variable or (y) graph A lines up perfectly because if you have ten additional people you have 10 x the cost per person wich = 10 and 10 x 10=100, if you start with 100 as the base cost and add 100 in additional people you will owe 200

Kayla has $45 and wants to buy three shirts that are originally priced at $18 each. They are on sale for 20% off. After applying 5% tax, does Kayla have enough money to purchase the three shirts
Answer: No, as the total cost of the 3 shirts w/ sales tax is $45.36 and she only has $45.
Step-by-step explanation:
Start by finding the price of one shirt on sale.
[tex]18*0.2[/tex]
This equals 3.6 which is how much will be deducted from the original price.
One shirt costs [tex]18-3.6\\[/tex] when its 20% off.
This is equal to $14.40.
Since she wants to buy 3 of them we just multiply the $14.40 by 3.
[tex]14.4*3=\\[/tex]
This equals $43.2 but this is without a 5% sales tax which is normally added to the total end price.
To add a sales tax you take the sales tax percent plus 1 and multiply it to the $43.2.
[tex]43.2*1.05=\\[/tex]
This means the total price of Kayla's purchase will be $45.36.
This is over her $45 she has so she can not buy it.
Answer: she does not and is over $45.36 (.36) cents over

Divided the two which is 80% so the increase is 20% I'm not good at explaining
Answer:
150-120=30
30/120=0.25
0.25=25%
25% is correct
120 x 0.25 = 30
120+ 30 = 150 so 25% is correct

What are the coordinates of the center of a circle whose equation is (x+1)^2+y^2=100?
Answer:
The center is (-1,0) and the radius is 10
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k)^2 = r^2
where the center is (h,k) and the radius is r
(x+1)^2+y^2=100
(x - -1)^2+(y-0)^2=10^2
The center is (-1,0) and the radius is 10
Answer:
radius = 10
center = (- 1, 0)
Step-by-step explanation:
eqn. of the circle = (x - h)^2 + (y - k)^2 = r^2
= (x + 1)^2 + y^2 = 100
(x - (-1))^2 + (y - 0)^2 =10^2
The center is (- 1, 0) and the radius is 10

Event A: lands on yellow.
Event B: lands on green.
Events A and B are a0 events.
Answer:
1/16
Events A+B are written (P) yellow : 1/4 * (P) green : 1/4
Ao event = (P) 1/4 * 1/4 = 1/16
Step-by-step explanation:
The probability of event A and event B is 1/16.
We have given that,
Event A: lands on yellow.
Event B: lands on green
Events A+B are written
yellow(P) = 1/4 * (P) green= 1/4
What is the meaning of probability?
Probability is defined as the likelihood of something occurring or the chance of something happening.
Ao event (P)=1/4 * 1/4
Event = 1/16
Therefore the probability of event A and event B is 1/16.

A piece of duct measures 48 inches. When pieces are fitted together, 1 12
inches is lost connecting each successive length of duct. On the job 7 and
12 pieces of ducting are used. What, in inches is the total length of the
finished duct?
Answer:
A piece of duct measures 48 inches.
In each connection, we lost 1 1/2 inches (i guess that it is what you wanted to write)
Then:
If we have 7 pieces of duct connected we have 5 connections (the ones in the extremes are not connected between them, so the number of connections is equal to the number of ducts minus two.)
So here we have 7 times 48 inches for the pieces, minus 5 times 1 1/2 in (i will write 1 1/2 = 1 + 0.5 = 1.5 in, so the math is easier) for the connections, the length is:
L = 7*48in - 5*1.5in = 328.5 inches.
for the 12 pieces duct, we have 12 pieces and 10 connections, so the length is:
L = 12*48in - 10*1.5in = 561 in
Now, if we want to make only one duct with those two, then we must add their lengths, but if we connect them, we also need to subtract the 1.5in of the new connection:
L = 561in + 328.5in - 1.5in = 888in

To find DC
c²=a²+b² (pythagorean theory)
c²=6²+8²
c²=36+64. c²=100. √100. c=10cm
thus D =10.
AD= 15-6=9
To find AC
c²=a²+b²
c²=15²+8²
c²=225+64. c²=289 √289. c=17
AC=17
perimeter is the distance around a figure thus ADC=9+10+17

(7x +6y)(49x^2 -42xy +36y^2)
Step-by-step explanation:
The factoring of the sum of cubes is a special form:
a³ +b³ = (a +b)(a² -ab +b²)
We recognize the given expression as a sum of cubes, so we can use this pattern to factor it.
Identifying the cubesFrom our memory of the cubes of small numbers (or from the cube root function of our calculator), we can identify the terms as ...
343x³ +216y³ = (7x)³ +(6y)³
ApplicationOur factoring pattern above can be used with ...
a = 7xb = 6ySubstituting these values, we have ...
343x³ +216y³ = (7x)³ +(6y)³ = (7x +6y)((7x)² -(7x)(6y) +(6y)²)
343x³ +216y³ = (7x +6y)(49x² -42xy +36y²)

Hitting the baseball over the lights
Meanwhile, at the ballpark, Juan was practicing his hitting while talking to the girls
standing around watching. He started telling them how he hit the ball over the 50 foot
light tower yesterday. The girls were unsure that he really did that.
The formula for this hit is: H(x)=-16x^2+60x+4 where h is the height of the ball and x is the number of seconds the ball is in the air.
How long did the ball actually hang in the air?
