Answer:
Step-by-step explanation:
Mean 0.7 and standard deviation 0.018
p = 0.07
n = 200
q = 1 - 0.07 which = 0.93
u = 0.07
o = (p * q) / n = [tex]\sqrt{(0.07)(0.93)/200}[/tex] = 0.018

The cost of 7 scarves is $47.25. What is the unit price?
The unit price is
per scarf.
Answer:
$6.75
Step-by-step explanation:
To find the unit price, just divide the total price ($47.25) by the quantity (7).
[tex]\frac{47.25}{7} = 6.75[/tex]
Write and expression for the calculation add 9 to the product of 4 and 5
Answer:
5×4+9
Step-by-step explanation:
The product of something means to multiply, so you would multiply 5 and 4 together.
Then you would add 9 to that.
Jim please help with my homework
3x – 3y = -9
4x + 4y= 12
show me the steps for substitution?
Answer:
y=3 and x=0
Step-by-step explanation:
3x−3y=−9. i'm going to solve for x.
3x−3y+3y=−9+3y
3x=3y−9
3x/3=(3y-9)/3 to isolate x we have to divide everything by 3
x=y−3
so now that we have x we can substitute it in 4x+4y=12
4(y-3)+4y=12
4y-12+4y=12
8y-12=12
8y-12+12=12+12
8y=24
8y/8=24/8
y=3
we have y which equals 3, so now we can substitute it into any equation so solve for x again.
3x – 3y = -9
3x-3(3)=-9
3x-9=-9
3x-9+9=-9+9
3x=0
3x/3=0/3
x=0
so, final answers are y=3 and x=0
checking our work:
3(0)-3(3)=-9
0-9=-9
-9=-9 true
4(0)+4(3)=12
0+12=12
12=12 true
PLEASE HELP::::::: Triangle PQR has medians QM and PN that intersect at Z. If ZM= 4, find QZ and QM
HELP HELP
Answer:
value of QZ = 8 units and QM = 12 units.
Step-by-step explanation:
Given: In triangle PQR has medians QM and PN that intersect at Z.
If ZM = 4 units.
In the figure given below; second median divided the two triangles formed by the first median in the ratio 2:1.
We have to find the value of QZ and QM;
QZ:ZM = 2: 1
⇒
Substitute the value of ZM =4 units and solve for QZ;
Multiply both sides by 4 we get;
Now, calculate QM;
QM = QZ+ZM = 8 + 4 = 12 units.
Therefore, the value of QZ and QM are; 8 units and 12 units
Pls help!!! Pls help!!!
This is a summation notation also called the sigma notation.
In this case it means starting with k=0 what's the sum of (1+k!) for all integer k until 4
So we just need to find the sum 1+0!+1+1!+1+2!+1+3!+1+4!=5+1+2+6+24=8+30=38

Hey eveyone. Im 7th grade 13 years old. Whenever i am at school i always think people think i smell bad. I dont know if its true. I put deoderant on take a shower and EVERYTHING. I dont wanna smell bad. It might just be in my head. Plz respond.
Answer:Researchers say a psychiatric condition characterized by a person's mistaken belief that he or she smells bad is vastly under-recognized. Called olfactory reference syndrome, the condition is "probably very common," says Katharine Phillips, MD, of Rhode Island Hospital in Providence. so you might just be thinking thst in your head man. just shower, brush teeth etc... or this could be a possibility...What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process.
Step-by-step explanation:
What is the solution of the following system? Use the substitution method.
y – 2x = 8
16 + 4x = 2y
O The only solution is (24, 0).
O The only solution is (1, 10).
○There is no solution.
O There are an infinite number of solutions.
Answer:
y-2x=8 (label equation 1)
16+4x=2y (label equation 2)
divide equation 2 by 2 to find y
y=2x+8
sub this in equation 1
(2x+8)-2x=8
2x+8-2x=8
8=8
once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B

arrange the variables so that they are on the same sides: -5w - 9 = 3w + 7
Answer:
-8w=16
Step-by-step explanation:
-5w-9+9 = 3w+7+9
-5w=3w+16
-5w-3w=3w-3w+16
-8w=16
To solve:
-8w/-8=16/-8
w = -2

Work out the value of x when y=5
Answer:
0.0000000164
Step-by-step explanation:
x= 4y^-12
for,
y = 5
x = 4×5^-12
x = 4/5^12
x = 4/244,140,625
x = 0.0000000164

Answer: 3, 37
Step-by-step explanation:
Divide by 3, divide by 3 again. 37 is a prime number, so it can't be divided again after that.
A box is made of wood with its external dimensions of 154 cm x 100 cm x 84 cm and thickness of 2 cm.
How much wood was used to make it?
Answer:
Step-by-step explanation:
volume of 154×100×84 box = 1,293,600 cm³
dimensions of airspace = (154-4) by (100-4) by (84-4) = 150 by 96 by 80
volume of airspace = 150×96×80 = 1,152,000 cm³
volume of wood used = 1,293,600 - 1,152,000 = 141,600 cm³

step 1 is wrong . The 1st step should be 15² - 9² = c² .
Answer: step A
Step-by-step explanation:
The Pythagorean theorem is a^2+b^2=c^2, where c is always the hypotenuse (the longest side of the triangle). Step A is written as 9^2(thats the a value squared)+15^2(which is the hypotenuse value squared)=c^2. It should be: 9^2+b^2=15^2
