Answer:b,e,f
Step-by-step explanation:
The correct equations are:
B) 0.4 = 2/5
D) 0.7 = 7/9
E) 0.83 = 5/6
To determine which of the following equations is correct, we need to compare each decimal value to its equivalent fraction. Here are the correct equations:
B) 0.4 = 2/5
D) 0.7 = 7/9
E) 0.83 = 5/6
B) 0.4 is equivalent to 2/5 because 0.4 means 4 tenths, and 2/5 also represents 4 tenths (2 parts out of 5).
D) 0.7 is equivalent to 7/9 because 0.7 means 7 tenths, and 7/9 also represents 7 tenths (7 parts out of 9).
E) 0.83 is equivalent to 5/6 because 0.83 means 83 hundredths, and 5/6 also represents 83 hundredths (5 parts out of 6).
The remaining options (A, C, and F) are not correct as their decimal values do not match their corresponding fractions.

best fit because it touches the most
points on a scatterplot when graphed.
Keene: The LSRL is the best line of best fit
because it has the smallest value for all the
squared residuals added together.

Answer:
2 2 /5 = 2.4 = 240 %
Step-by-step explanation:
The number 1 is the same as 1.00 and is the same as 100%.
The number 2, therefore, is the same as 2.00 and the same as 200%
2 /5 can be converted into a decimal by seeing that 2 /5 = 4 /10 . 4 /10 , spoken out loud, is "four tenths" and shows that the decimal is
0.4 . And 0.4 is the same as 40%. Which means that 2 2 /5 = 2.4= 240 %

A prime number is an integer greater than 1 with exactly two different positive factors, 1 and the number itself. There are three children in a family. Each of their ages is a prime number. The sum of their ages is 41 and at least two of the children have ages that differ by 16. Determine all possibilities for the ages of the children.
Answer:
Hence,
a=19,b=19,c=3
a=11,b=7,c=23
Step-by-step explanation:
[tex]Let\ their\ ages\ be\ a,b\ and\ c\ respectively, where\ a,b,c\ are\ primes\\Hence,\\a+b+c=41\\b-c=16\\Listing\ out\ all\ the\ primes\ from\ 0\ to\ 41\ we\ get:\\2,3,5,7,11,13,17,19,23,29,31,37,\\Hence,\\Lets\ seperate\ out\ the\ primes\ who\ differ\ by\ 16 :\\3\ and\ 19, 7\ and\ 23\ ,[/tex]
Hence,
[tex]Lets\ consider\ this\ set\ as\ b,c:\\Hence,\\To\ find\ a \\a=41-(b+c)\\Hence, By\ doing\ this\ indiviually\ we\ get:\\[/tex]
[tex]a=41-(19+3)\\a=41-22\\a=19\\Hence, a=19,b=19,c=3[/tex]
[tex]a=41-(23+7)\\a=41-30\\a=11\\Hence, a=11,b=7,c=23[/tex]
Find the slope and y-intercept of the line whose equation is given.
y= - 7x-9
Determine the slope. Select the correct choice below and fill in any answer boxe
A. m=
(Type an integer or a fraction.)
OB. The slope is undefined.
Answer:
Slope = -7
y-intercept = -9
Step-by-step explanation:
The slope formula is y = mx + b where m is the slope value and b is the y-intercept value. In this case, since both values have a negative sign in front of them, they are both negative.
y = mx + b
y = -7x - 9
m = -7 which is the slope
b = -9 which is the y -intercept

Simipified the exprestion -1.7+(-6.3).On the test when maureen simipified the exression she got -4.6. What mistake did maureen likley make when she simipified the question
Answer:
Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7
Step-by-step explanation:
-1.7 + (-6.3)
Correct simplification
-1.7 + (-6.3)
Open parenthesis
= - 1.7 - 6.3
= -8
NOTE:
- * + = -
- * - = +
+ * - = -
+ * + = +
Maureen's simplification
-1.7 + (-6.3)
= 1.7 - 6.3
= -4.6
Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7

How many hours did he take to drive one mile?
Answer: 1.89 minutes
Step-by-step explanation: If we take 1 and 1/3 hours and turn that into minutes we get 80 minutes we then divide it by the number of miles 42 1/3. We would get about 1.89, so it took about 1.89 minutes

Find the value of x if C is the midpoint of line segment AB, AC=4x+5, and
AB=78?
Answer:
x = 8.5
Step-by-step explanation:
AC + CB = AB
As C is the midpoint AC = CB = 4X + 5
AC + CB = AB
4x + 5 + 4x + 5 = 78
4x + 4x + 5 + 5 = 78 {Combine like terms}
8x + 10 = 78 {Subtract 10 from both sides}
8x = 78 - 10
8x = 68
x = 68/8
x = 8.5

Find the error in the calculations shown, and then evaluate the expression correctly.
-3.8 - (7.2 - 10 3/8
3.8+(-7.2 - 10 3/8
(-3.8+(-7.2)) – 10 3/8
- 11 - 10 3/8
11+ 10 3/8
21 3/8
Answer:
-3.8 - (7.2-10 3/8)
-3.8+(-7.2+10 3/8) this is the error, it's positive 10 3/8, not negative, then you should solve what's in the parentheses first
I simplified 10 3/8 into 83/8 and then 10.375
-3.8+(-7.2 + 10.375)
-3.8+ 3.175 = -0.625
NEED HELP PLEASE!!! Lionel created a scatter plot and drew a line of best fit, as shown.
What is the equation of the line of best fit that Lionel drew?
Answer: A.
Y=-2x+16
Step-by-step explanation:
You gotta find the pretty points on the line of the linear function. Then you have to find the slope (rise over run) with those pretty points. Then you have to use a coordinate (I used 6,4) to find the y intercept. Then you solve the equation, by plugging in all the numbers :) hope this helps.
