Answer: 7410 watches
Step-by-step explanation:
From the random sample of 250 watches, 3 are defective. The percentage that's defective will be:
= 3/250 × 100
= 1.2%
Percentage that's not defective = 100 - 1.2 = 98.8%
Therefore, from the sample of 7500 watches, the number that's not defective will be:
= 98.8% of 7500
= 98.8/100 × 7500
= 7410
Therefore, 7410 watches aren't defective
Solve the equation
2.9=7.1 + y
Answer:
y=-4.2
Step-by-step explanation:
2.9=7.1+y
2.9-7.1=7.1-7.1 +y
-4.2=y or y= -4.2
y = -4.2
If you substitute that value for y into the equation, you'll get 2.9 = 7.1 + (-4.2)... and that is a correct, valid equation. HOPE THAT HELPS!

Simplify; (³√729)³ + 24
Answer:
[tex](\sqrt[3]{729} )^{3}[/tex] + 24 can be simplified to 753.
Step-by-step explanation:
If you take the root of a number to a specific number, then square that by the same number you took the root by, then you will have the same number you started with. In this case, [tex]\sqrt[3]{729}[/tex] equals 9, and [tex]9^{3}[/tex] equals 729, so [tex](\sqrt[3]{729} )^{3}[/tex] equals 729. 729 + 24 = 753, so that is the simplified answer.

y = 1x
Step-by-step explanation:
(0,0) (-5,-5)
y2 - y1 / x2 - x1
-5 - 0 / -5 - 0

y = 1x + b
-5 = 1(-5) + b

John is placing cement tiles for a patio in a rectangle surrounding a
rectangular fire pit. The fire pit has a width of x ft and a length that is 4
times the width. The entire patio is 9 ft wider and 13 ft longer than the fire
pit. What is the area that he will need to buy tiles for?
Answer:
31x + 55 sq. ft.
Step-by-step explanation:
Width of Fire Pit = x ft. Length of Fire Pit = 4x ft.
Width of Patio = x + 5 ft. Length of Patio = 4x + 11 ft. Area of Fire pit = 4x * x = 4x² sq, ft.
Total Area of Rectangular Patio (including Fire pit) = (4x + 11)(x+5)
= 4x² + 31x + 55 sq. ft.
Area for which tiling is done = Area of Rectangular patio - Area of fire pit
= 4x² + 31x + 55 - 4x²
= 31x + 55 sq. ft.

Step-by-step explanation:
What is the question?
The line plot below shows the lengths of bolts Mr. Slivka found in his drawer.
He needs 16 bolts that are longer than 1 inch for a project he is working on.
Does he have enough bolts for his project?
A line plot named
A.
Yes. There are 16 bolts that have lengths greater than 1 inch, which is just enough.
B.
Yes. There are 18 bolts that have lengths greater than 1 inch, which is more than enough.
C.
No. There are only 3 bolts with lengths greater than 1 inch, which is not enough.
D.
No. There are only 12 bolts that have lengths greater than 1 inch, which is not enough.
Answer:
D.)
No. There are only 12 bolts that have lengths greater than 1 inch, which is not enough.
Step-by-step explanation:
Based on information provided by the dot plot above, we can deduce that the number of bta longer Than 1 inch are those with length ; 1 1/8, 1 3/8, 1 4/8
Counting the number of these bolts :
1 1/8 = 5 bolts
1 3/8 = 3 bolts
1 4/8 = 4 bolts
Hence, total number of bolts longer Than 1 inch :
(5 + 3 + 4). = 12 bolts
The number of bolts longer than 1 inch is 16. Therefore, he does not have enough bolt for the project.

You spin the spinner shown. The spinner lands on blue or green.
Answer:
[tex]$\frac{1}{3}$[/tex] , 0.33 , 33%
Step-by-step explanation:
The spinner has 4 green, 4 blue and 4 yellow.
So total = 12
Therefore, the probability of the spinner landing on blue or green as a fraction is = [tex]$\frac{4}{12}$[/tex]
[tex]$=\frac{1}{3}$[/tex]
The probability of the spinner landing on blue or green as a decimal is = 0.33
The probability of the spinner landing on blue or green as a percent is
= 0.33 x 100
= 33 %
A company used 7.4 x 105 sheets of paper a month, the accounting department used 8.9 x 103 sheets. How many were used by other departments during the month
Answer:
731,100
7.311 × 10^5
Step-by-step explanation:
The computation of the number of sheet used by other department is given below:
Given that
The company used 7.4 × 10^5 sheets of paper So it would be 740,000
And, The accounting department used 8.9 × 10^3 sheets so it would be 8,900
Now the number of sheet used by other department is
= 740,000 - 8,900
= 731,100
= 7.311 × 10^5
Help!! Solve 1 1/4 + 5 5/6
Answer:
7 2/24
Step-by-step explanation:
We can start by making the denominators the same (the bottom number)
1 1/4+5 5/6
1 6/24+ 5 20/24=7 2/24
Answer:
so what you would want to do is get your fraction into improper fractions and to do that you multiply the whole number by the denominator and add it to your numerator, once you do that you get 5/4, and 35/6, now we want to get common denominators, so we multiply 5/4, by 6/6, and 35/6 by 4/4 which would get us 30/24 and 140/24 then we add them and get 170/24 and then simplify, which gets you 85/12 and then put it into a mixed number which is 7 1/12

Fantasy 5 lottery game is picking 5 numbers from 1-41. If you match them all you win the jackpot. What is the probability you win the jackpot?
Answer:
1 / 89927760
Step-by-step explanation:
Recall :
Probability = required outcome / Total possible outcomes
To pick five number for a lottery from the range (1 - 41) ;
For this scenario, selection will be done without replacement
To win lottery , all 5 selections must be matched
P(1st pick) = 1 / 41
P(2nd pick) = 1 /40
P(3rd pick) = 1/39
P(4th pick) = 1/38
P(5th pick) = 1/37
(1/41 * 1/40 * 1/39 * 1/38 * 1/37) = 1 / 89927760
Hence, Probability of winning lottery = 1 / 89927760
Find two numbers that have a sum of -2 and a product of -48 (please show work if possible)
Answer: -8 and 6
Step-by-step explanation:
factors of 48: 1,2,4,6,8,12,24,48
1 x 48
2 x 24
4 x 12
6 x 8
for a negative product, one of the factors must be negative and the other positive.
for two number to have a sum of -2, the greater number must be the negative number, and both numbers should have be two values apart (ex. 6 and 8, 3 and 5, 12 and 14, etc.). In this case, 8 would have to be negative whereas 6 will be left positive.
and then we check:
-8 x 6 = 48
-8 + 6 = -2

PLZZZZZ HELPPPP!!!! i'm very confused on what to do !!!! what is the length of the apothem of a regular hexagon with 16cm side lengths round to the nearest tenth
Answer:
A = 4.6 cm
Step-by-step explanation:
Here, we want to find the length of the apothem, given the side lengths
Mathematically, we have this as;
A = s/2 tan (180/n)
where in this case;
s is the length of the sides which is 16 cm
n is the number of sides (since it is hexagon, we have this as 6)
Substituting these values;
A = 16/2 * tan (180/6)
A = 8 * tan 30
A = 4.62
To the nearest tenth, A is 4.6 cm
Find sin D, sin E, cos D, and cos E. Write each answer as a fraction in simplest form.
Answer:
1- 35/37
2- 12/37
3- 35/37
4- 12/37
Step-by-step explanation:
The sine of an angle is the ratio of the opposite to the hypotenuse while the cos of an angle refers to the ratio of the adjacent to the hypotenuse. Therefore, the following is true:
Sin D = opposite/hypotenuse = 35/37 -has no simplest form Sin E = opposite/hypotenuse = 12/37 -has no simplest form Cos D = adjacent/hypotenuse = 12/37 -has no simplest form Cos E = adjacent/hypotenuse = 35/37 -has no simplest form
These are fractions that can't be simplified, so they remain the same.
Hope this helps!!

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be represented as ΔDEF
Now , the measure of sides of triangle are
The measure of side DE = 37
The measure of side EF = 35
The measure of side DF = 12
Now , from the trigonometric relations
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
On simplifying , we get
sin D = 35/37
sin E = 12/37
cos D = 12/37
cos E = 35/37
Hence , the measures of trigonometric relations are solved
