Solve the equation step by step
Let x be the amount of salt in the solution.
At day's end, the concentration of salt in the beaker is
x / (4 L) = 0.08 = 8%
Solve for x to get
x = 0.08 (4 L) = 0.32 L
So at the beginning, the concentration of salt in the beaker was
(0.32 L) / (5 L) = 0.064 = 6.4%
how many pounds are the squares to make them equal?
Answer:
hmm
try keeping 1.5
lhs = 1 + 1 + 1.5 + 1.5 + 1.5 = 6.5
rhs = 1+1+1+1+1 + 1.5 = 6.5
hence ans is 1.5

For a given sample size in hypothesis testing, a.Type II error will not be effected by Type I error. b.the smaller the Type I error, the larger the Type II error will be. c.the smaller the Type I error, the smaller the Type II error will be. d.the sum of Type I and Type II errors must equal to 1.
Answer:
B.the smaller the Type I error, the larger the Type II error will be
Step-by-step explanation:
In hypothesis, type I error is when we reject the null hypothesis even though it's true while type II error is when we accept the null hypothesis even though it is false.
Now, the type I error is based on the significance level alpha. While the type II error is based on the statistical power beta.
This means that the significance level will affect the statistical power and we know that the significance level is inversely related to the Type II error rate based on beta.
Therefore, we can conclude that;
Having a lower significance level will lead to a decrease in the risk of getting a Type I error, however, it will increase the possibility of having a Type II error.
Thus, option B is correct.
There were 642 students enrolled in a freshman-level chemistry class. By the end of the semester, the number of students who passed was 5 times the number of students who failed. Find the number of students who passed and the number who failed.
Answer:
535 students passed and 107 students failed
Step-by-step explanation:
Create a system of equations where p is the number of students who passed and f is the number of students who failed:
p + f = 642
p = 5f
Solve by substitution by plugging in 5f as p into the first equation, then solving for f:
p + f = 642
5f + f = 642
6f = 642
f = 107
So, 107 students failed.
Find how many students passed by multiplying this by 5:
107(5)
= 535
535 students passed and 107 students failed.
Square root of 64 + cube root of 64 is
Answer:
12
Step-by-step explanation:
[tex]\sqrt{64}[/tex] + [tex]\sqrt[3]{64}[/tex]
= 8 + 4
= 12
Square root of 64 = [tex] \sf \sqrt{64} = \sqrt{8 \times 8} = \boxed{\bf 8}[/tex]
Cube root of 64 = [tex] \sf \sqrt[3]{64} = \sqrt[3]{4 \times 4 \times 4} = \boxed{ \bf4}[/tex]
So,
Square root of 64 + Cube root of 64
[tex] = \sf \sqrt{64} + \sqrt[3]{64} \\ \sf = 8 + 4 \\ = \boxed{ \bf12}[/tex]
12 is the answer of the question asked.

"Find the area and the circumference of a circle with diameter of 8m"
Radius = diameter/2 = 8/2 = 4m
Area of a circle = pi x r^2 = pi x 4^2 = 16pi m^2 ( exact area) or 50.27 m^2
Circumference = pi x diameter = 8pi m ( exact) or 25.12 m
Answer:
C = 25.12 A = 50.24
Step-by-step explanation:
Circumference formula = dπ
Area formula = πr^2
Circumference:
Plug in:
8π
8 × 3.14 = 25.12
Area:
8/2 = 4
r = 4
Plug in:
πr^2
π4^2
16π
16 × 3.14 = 50.24
Hope this helped.

Solve according to BODMAS.
Answer:
Solution :To solve the above equation we will follow the BODMAS rule.
>> BODMAS is an order of mathematic operations.>> BODMAS rule is to be followed while solving expressions in mathematics.It stands for :

Solving the question by bodmas rule :
[tex] \tt{ = 2 \times 1 + 52 - 36 \div 2}[/tex]
[tex] \tt{ = 2 \times 1 + 52 - \dfrac{36}{2}}[/tex]
[tex] \tt{ = 2 \times 1 + 52 - \cancel{\dfrac{36}{2}}}[/tex]
[tex] \tt{ = 2 \times 1 + 52 - 18}[/tex]
[tex] \tt{ = 2 + 52 - 18}[/tex]
[tex] \tt{ = 54 - 18}[/tex]
[tex] \tt{ = {\underline{\underline{\red{ \: 36 \: }}}}}[/tex]

Find the area of the figure below. Use 3.14 for pi.
Step-by-step explanation:
As we can say that,
diameter=10 cm
to find radius ,
radius =diameter/2
5cm
now, we can say
Area of semi circule= 1/2 ×3.14 ×5^2
=3.14 ×25/2
= 39.25 cm^2
also,Length =14 cm now,
area of square= l^2
=14×14
196cm^2
now ,total area of figure =196+39.25=235.25cm^2
therefore, total area is 235.25cm^2
K is between J and M. L is
between K and M. M is
between K and N. If JN = 30, KM = 8, and JK = KL = LM, what is MJ?
(please do step-by-step fully)
Answer:
12
Step-by-step explanation:
for this you need to draw a straight line and plot the points J,K,L,M,N according to the question.
here,
given K lies between J and M, L is between K and M , M is between K and N.
JN= 30, KM=8
JK=KL=LM
MJ= ?
according to the question,
J--------K-------L--------M-------N
KM= 8
KL+LM= 8 (KL+LM=KM)
KL+KL=8 ( given, LM=KL)
2KL= 8
KL=4
so,
JK= KL=4 and LM= KL= 4
now,
MJ= ?
we know
MJ= JK+KM = 4+8= 12

Help school is so bad
Answer:
7.A (5,1)
B(5,7)
8. D (0,6)
Step-by-step explanation:
7. One vertex is at (5,4)
Move 3 units either direction in x
(5-3,4) = (2,4)
(5+3,4) = (8,4)
Or move 3 units in the y direction
(5,4+3) = (5,7)
(5,4-3) = (5,1)
If x is less than 2 or greater than 8 it is too far from the one vertex we are given
If y is less than 1 or greater than 7 it is too far away from the one vertex we are given
C cannot be a vertex since y =9
D is not a vertex since the point is (2,6) and not (2,4) which we know is 3 units away
E is not a vertex since the point is (2,1) and not (2,4) which we know is 3 units away
8. The center is (0,0)
The points have to add to a radius of 6
r^2 = 36
The sum of the x^2 and y^2 = 36
3^2 +0^2 = 9
4^2 +2^2 = 16+4 = 20
5^2 +3^2 = 25+9 = 34
0^2+6^2 =36 yes for D
4^2 +4^2 =16+16 = 32
1^2+5^2 = 26
jojo is twice as Old as esi who in turn is five years older than kweku . if their total age is 47,how is each of them
Answer:
jojo is 26
esi is 13
and kweku is 8 years old.
Step-by-step explanation:
Let esi's age be x then jojo's age is 2x.
Also kweku's age is x - 5. as esi is 5 years older than kweku.
So x + 2x + x - 5 = 47
4x = 47 + 5 = 52
x = 13.
So jojo's age is 2*13 = 26 and kweku's age is 13 - 5 = 8.
