84, 67, 74, 87, 67, 73
What is the mean of their scores?
20
67
73.5
75.3
Answer:75.3
Step-by-step explanation:
Add all the numbers then divide by how many numbers their are
Answer:
75.3
Step-by-step explanation:
You add all the numbers together and you get 452. Then you you divide 452 by how many numbers are in the set which is 6 and you get 75.2 but since there is 75.3 but no 75.2, 75.3 is your anwser.
Hope this explains a lot!!!!!!!!!!!!!!
For the equation 3(7+x)=3x+k, what value of k will create an equation with infinitely many solutions?
Answer: k = 21
Step-by-step explanation:
3(7 + x) = 3x + k
21 + 3x = 3x + k
21 + 3x - 3x = 3x + k - 3x
k = 21
Is 14,48,50 a Pythagorean triplet
Step by step explanation please
Answer:
yes
Step-by-step explanation:
If the values are a Pythagorean triplet then the square of the largest value should equal the sum of the squares of the other 2
largest value = 50 ⇒ 50² = 2500
14² + 48² = 196 + 2304 = 2500
Since 50² = 14² + 48² then 14, 48, 50 are a Pythagorean triplet
Factor f(x) = 4x2 + 11x? - 104x + 105 into linear factors given that – 7 is a zero of f(x).
f(x) = 4x + 11x2 - 104x + 105 = |
(Factor completely.)
Answer:
f(x) = 4x + 11x2 - 104x + 105 = (x - 3)(x + 7)(4x - 5)
Step-by-step explanation:
f(x) = 4x^3 + 11x2 - 104x + 105
has the coefficients {4, 11 -104, 105}. We perform synthetic division using the given -7 as divisor:
-7 / 4 11 -104 105
-28 119 -105
-----------------------------------
4 -17 15 0
Since the remainder is zero (0), we have shown that -7 is a zero of f(x). The coefficients of the quotient (above) are {4, -17, 15}. Let's try factoring the corresponding polynomial again using synthetic division. Start out by using 5 as divisor and determining whether or not the remaindeer is zero:
5 / 4 -17 15
20 15
-------------------------
4 3 30 No, the remainder is 30 and so 5 is not a
root of this quadratic. Try the divisor 3 instead:
3 / 4 -17 15
12 -15
---------------------------
4 -5 0 Yes, the remainder is 0 and so 3 is a root.
Thus, the given f(x) = 4x + 11x2 - 104x + 105 factors as follows:
f(x) = 4x + 11x2 - 104x + 105 = (x - 3)(x + 7)(4x - 5). Notice that the coefficients of the last factor come from those we found above when using 3 as a divisor in synthetic division.

D Each landscaper works 12 hours a day
An orchand has 8 times more apple trees than pear trees. There are 981 trees in all. How many more apple trees are there
Answer:
763
Step-by-step explanation:
there are 763 more apple trees than pear trees
Step-by-step explanation:
so, first we write the words into equations.
8P = A because there are 8x apples per x pear, so to make it equal we must multiply pears by 8. P+A = 981. replacing "A" in the second equation with "8P" to get P+8P=981=9P divide both sides by 9 to get 109 pear trees. knowing this we can get 981-109=A=872 apple trees. the problem asks for A-P which we can replace the numbers to get (872)-(109)=763 more trees
Answer:122.625
Step-by-step explanation:981 divided by 8 equals 122.625
It is solving equations, Please tell me the answers and if you can show the work then that would be nice too.

Jimarcus plans to build a free fence 5 1/3 yards long at the back of his garden. How many 2/3- yard sections of fence will he need
Answer:
8
Step-by-step explanation:
Jimarcus plans to build a fence of 5 1/3 yards longs
He want to divide it into 2/3 yard sections
Therefore the number that will be produced can be calculated as follows
= 5 1/3 ÷ 2/3
= 16/3 ÷ 2/3
= 16/3 × 3/2
= 16/2
= 8

School A has graduated 1,700 students and graduates
50 students every year. School B has graduated 600
students, but graduates 150 every year. How many years (Y)
will it be before School B has as many graduates as School A?
Answer:
the answer is 11 years
Step-by-step explanation:
if school A is graduated 50/years,
the graduated in 11 years is 550
added of graduated 1,700 in 550 is 2,250
if school B is graduated 150/years,
the graduated in 11 years is 1650
added of graduated 600 in 1650 is 2,250
so School A and B is to be equal in 11 years
The height of 5 boys is 5.4 ft, 6.12 ft., 7.02 ft. 4.9 ft, and 6.25 ft. What is the average
height of these 5 boys?
What are the operation to solve the problem?
pls answer
Wll not just this question, but whenever you need to find average, you have to:
Wait, for example let's take ur question:
1st step we will add up all the values aka heights:
5.4+6.12+7.02+4.9+6.25=29.69
And then how many values did you take???
Its, 5 values
1st value= 5.4
2nd value=6.12
aaand so on....
However, then we will have to divide the sum by no.of values
29.69÷5=5.938
Aaand this is your FINAL ANSWER
Done!!!!
Hope I helped you!!!
Step-by-step explanation:
For the average height of fhe boys:
[tex] \frac{5.4ft + 6.12ft + 7.02ft + 4.9ft + 6.25ft}{5} \\ = 5.938 \: ft[/tex]
In solving for the average height, we used addition and division operations.

Step-by-step explanation:
Solve this literal simultaneous equation for x and y.
[tex]ax+by=c[/tex]
[tex]bx+ay=c[/tex]
Answer:
The answer is below
Step-by-step explanation:
Firstly, let us find the value of x. Multiply the first equation by a and the second equation by b to get:
a²x + aby = ca (3)
b²x + aby = cb (4)
Subtract equation 4 from equation 3 to get:
x(a² - b²) = c(a - b)
but a² - b² = (a + b)(a - b)
x(a + b)(a - b) = c(a - b)
x(a + b) = c
[tex]x=\frac{c}{a+b}[/tex]
Secondly, let us find the value of y. Multiply the first equation by b and the second equation by a to get:
abx + b²y = cb (5)
abx + a²y = ca (6)
Subtract equation 5 from equation 6 to get:
y(a² - b²) = c(a - b)
but a² - b² = (a + b)(a - b)
y(a + b)(a - b) = c(a - b)
y(a + b) = c
[tex]y=\frac{c}{a+b}[/tex]
