Answer:
6 and 10
Step-by-step explanation:
4+5+10= 19
19/3 is around 6.3333 and since our mean is 7 we will need a number higher than 6 so either 7,8,or 9
Also if our median is 6, six needs to be added
Let’s try using 6&7
4+5+6+7+10= 32/5- 6.4 NOT 7
4+5+6+8+10=33/5- 6.6- maybe 8
4+5+6+9+10= 34/5-6.8- maybe 9
4+5+6+10+10=35/5- perfect match!!!!

A map has a scale of 1:200000 How far is it from Belfast to Larne in Km if the distance on the map is 7.8cm
Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km

Which type of graph would be best for showing the average yearly bonus amounts for employees in different departments of an IT company?
A. a bar graph
B. a circle graph
C. a histogram
D. a line graph
Answer:
I believe that a bar graph will help with that, because you can narrow the answers down to a bar graph and a line graph but a line graph will only show an increase and a decrease not an average, and a bar graph shows all three.

Find the interquartile range of the data.
84,75,90,87,99,91,85,88,76,92,94
IQR is shorthand for interquartile range
=========================================================
Explanation:
The original list is {84,75,90,87,99,91,85,88,76,92,94}
It sorts to {75,76,84,85,87,88,90,91,92,94,99}
Pick out the middle most value, which is 88 in slot 6. A quick way to get here is to see that there are n = 11 values in this set. So n/2 = 11/2 = 5.5 which rounds to 6, and that tells us the slot number where the median is held. If n is an even number, then you'll need to use the midpoint formula for the two middle-most items.
After we determine the median is 88, we split the sorted data set as follows:
L = {75,76,84,85,87}
U = {90,91,92,94,99}
Everything in set L is below the median. L for lower.
Everything in set U is above the median. U for upper.
Sets L and U have 5 items each. Note that 5+1+5 = 11 = n.
-------------
The median of set L is 84, so Q1 = 84
The median of set U is 92, so Q3 = 92
Q1 and Q3 are the first and third quartiles respectively. Subtracting them gets us the IQR (interquartile range)
IQR = Q3 - Q1
IQR = 92 - 84
IQR = 8
The IQR helps give us a sense how spread out the data set is. It's similar to the range, which is found by range = max - min. The larger the (interquartile)range, the more spread out the data set will be.
Anne made a recipe for miniature bread loaves that called for StartFraction 7 Over 8 EndFraction of a cup of whole-wheat flour. If the recipe made 7 equal-sized loaves of bread, how many cups of whole-wheat flour did each loaf contain?
StartFraction 1 Over 8 EndFraction of a cup
Answer:
8 loaves
Step-by-step explanation:
so each loaf contains 7/8 cups flour
there are 7 loaves
7 ÷ 7/8 = 8
Answer:
1/8
Step-by-step explanation:
So if the entire recipe makes 7 loaves and calls for 7/8 of a cup, you would need to split the 7/8 cups flour into 7. 7/8 ÷ 7=1/8.

Camilla's employer pays 90% of the total cost of her family's health insurance
plan, while Camilla pays the rest. If the total cost of the plan increases from
$850 per month to $950 per month, how much more will Camilla have to pay
each month?
A. $90
O B. $10
O C. $100
D. $9
Answer:
B. $10
Step-by-step explanation:
Camila's employer pays 90% of the total cost of her family's health insurance
plan
Therefore, Camilla pays only 10%
If the total cost of the plan increases from $850 per month to $950 per month, how much more will Camilla have to pay
each month?
Amount of health insurance Camilla pays at $850 per month = 10% of $850
= 0.1 * $850
= $85
Amount of health insurance Camilla pays at $950 per month = 10% of $950
= 0.1 * $950
= $95
Amount Camilla pays more = $95 - $85
= $10
B. $10
Cooks are needed to prepare for a large party. Each cook can bake either 5 large cakes or 14 small cakes per hour. The kitchen is available for 2 hours and 24 large cakes and 130 small cakes can be cake. How many cooks are required to bake the required number of cakes during the time the kitchen is available
Answer:
8
Step-by-step explanation:
In 2 hours
1 cook makes 10 large cakes
24/10 = 2.4
You need 3 cooks to make the large cakes.
In 2 hours
1 cook makes 28 small cakes
130/28 = 4.64
You need 5 cooks to make the small cakes.
3 + 5 = 8

What’s the distance between the points that’s given on the graph?
The distance between two points:
[tex] \large \boxed{ \sqrt{(x_2 - x_1)^{2} + {(y_2 - y_1)}^{2} } }[/tex]
From the graph, the given points are (-3,1) and (5,-4). Substitute the points in as we get:
[tex] \large{d = \sqrt{ {( - 3 - 5)}^{2} + {(1 + 4)}^{2} } } \\ \large{d = \sqrt{ { (- 8)}^{2} + {5}^{2} } } \\ \large{d = \sqrt{64 + 25} \longrightarrow \sqrt{89} } [/tex]
Hence the distance between two points is √89.
Answer
√89What is the slope and y-intercept of y=-5/4x+4 and the slope and y-intercept of y=3/2x-7

pls answer asap 7 - 3 r = r - 4 ( 2 + r)
Answer:
no real answer
Step-by-step explanation:
distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r
then we have 7-3r=-8-3r
from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.
since 7 doesn't equal -8, there is no answer.
if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers
A wildlife refuge has 200 birds when it is first established. It is so
successful that the number of birds increases by 25% every year.
Write a function to model the situation.
Find the number of birds present after 7 years.
Answer:
550 birds
Step-by-step explanation:
25% × 7 = 175%
100% + 175% = 275%
[tex]\frac{y}{200} :\frac{275}{100}[/tex]
y × 100 = 275 × 200
100y = 55000
100y ÷ 100 = 55000 ÷ 100
y = 550
Answer:
200*1.25ˣ
954
Step-by-step explanation:
let x= years
200*1.25ˣ = birds
plug in 7 for x
200*1.25⁷=953.6743164
round to 954

Answer:
A
Step-by-step explanation:
64 ^1/4
What number multiply by itself 4 times =64
m*m*m*m = 64
Rewriting 64 as 16*4
(16*4) ^1/4
We can rewrite this as
16 ^ 1/4 * 4^1/4
We know 16 ^ 1/4 = 2
2 * 4 ^ 1/4
Answer:
4
Step-by-step explanation:
64 ¼
Any number multiply by itself 4 times = 64
Let no. be x.
x × x × x × x = 64
x ⁴ = 64
Taking square root of each side
√ x⁴ = √64
x² = 8
Now, again Taking square root
√x² = √8
x = 4

Answer:
416 ft
Step-by-step explanation:
We will start with the easiest shape.
10 x 4 x 4 = 160
We will put that to the side and continue.
we see that 20 feet is the whole height of the object but since there is the height of 4 feet on the bottom shape, we will take 4 from 20 to give us 16 feet for the top shape.
16 x 4 x 4 = 256
Now, we add the totals.
256 + 160 = 416
Answer:
