Solve the equation. 9x−(3x+9)=2x−25 Select the correct choice below and fill in any answer boxes in your choice. A. The solution set is (Simplify your answer.) B. There is no solution.
Answer: Choice A, x=-4
Step-by-step explanation:
1. 9x−(3x+9)=2x−25
2. 9x-3x-9=2x-25
3. 6x-9=2x-25
4. 6x-9=2x-25
-2x -2x
5. 4x-9=-25
+9 +9
6. 4x=-16 (divide both sides by 4)
7. x=-4
The amounts of vitamin C (in milligrams) for 100g (3.57 ounces) of various randomly selected fruits and vegetables are listed. Is there sufficient evidence to conclude that the standard deviation differs from 12 mg? Use alpha = 0.10. Use a graphing calculator with the program SDHYP and the P-value method. Source: Time Almanac 2012. State the hypotheses and identify the claim with the correct hypothesis. H_0: sigma H_1: sigma This hypothesis test is a (select) test.
Answer:
H0: sigma=12
H1:sigma≠12
This hypothesis test is a two tailed test.
Step-by-step explanation:
The null value described in the statement is 12 mg. So, the null hypothesis would be sigma=12. As the statement states that whether there is sufficient evidence to conclude that standard deviation differs from 12 mg, so the alternative hypothesis would be sigma ≠12. The alternative hypothesis contains inequality sign so, the hypothesis test is a two tailed test.

What number should be added to 78to get a sum of 97
THE ANSWER TO THAT PROBLEM IS SIMPLY 175
Answer:
19
Step-by-step explanation:
All you need to do is subtract 78 from 97 to find the "remainder." Or you can also add until you get to 97.
97 - 78 = 19
78 + 19 = 97.

The Jurassic period began approximately 200 million years ago. Approximate how many minutes have passed since the beginning of this period to the present day?
Answer:
Step-by-step explanation:
The exact result is 1.0518984 x 1011 Minutes
(sorry if this doesn't make much sense)
The required number of minutes have passed from the beginning of this period to the present day is 1.0512 * [tex]10^{14}[/tex] minutes
Given that,
The Jurassic period began approximately 200 million years ago. Approximate how many minutes have passed from the beginning of this period to the present day is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
200 million = 200 * [tex]10^6[/tex]
Now,
200 * [tex]10^6[/tex] year = 200 * [tex]10^6[/tex] * 365 days
200 * [tex]10^6[/tex] * 365 days = 200 * [tex]10^6[/tex] * 365 * 24 hours
200 * [tex]10^6[/tex] * 365 * 24 hours = 200 * [tex]10^6[/tex] * 365 * 24 * 60 minutes
= 1.0512 * [tex]10^{14}[/tex] minutes
Thus, the required minutes that have passed from the beginning of this period to the present day is 1.0512 * [tex]10^{14}[/tex] minutes.

Find the area of a circle with a radius of 11 inches. Use a 3.14. The area of the circle is approximately
inches. Enter only the number.
Answer:
A = 379.94 square inches
Step-by-step explanation:
The area of a circle equation is:
A = pi * r^2
Fill in what you know and solve:
A = 3.14 * 11^2
A = 3.14 * 121
A = 379.94
The area of the circle is 379.94 square inches.
What is area of a circle?The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.
Given that, the area of a circle with a radius of 11 inches.
Here, area of a circle is
A=3.14×11²
= 3.14×121
= 379.94 square inches
Therefore, the area of the circle is 379.94 square inches.

find the solution of 4t - 2 = 9
Answer:
t = 11/4
Step-by-step explanation:
Step 1: Write out equation
4t - 2 = 9
Step 2: Add 2 on both sides
4t = 11
Step 3: Divide both sides by 4
t = 11/4
Answer:
[tex]t = 2\frac{3}{4} \\\\t = 11/4[/tex]
Step-by-step explanation:
[tex]4t -2 =9[/tex]
Collect like terms and simplify
[tex]4t=9+2\\\\4t =11[/tex]
Divide both sides of the equation by 4
[tex]\frac{4t}{4} = \frac{11}{4} \\\\t = \frac{11}{4} \\\\11\div 4 =2 \:remainder\: 3\\\\= 2\frac{3}{4}[/tex]

Step-by-step explanation:
does rational numbers, irrational numbers, integers or whole numbers have the fewest numbers
Answer:
Whole Numbers
Step-by-step explanation:
whole numbers are just the counting numbers starting from zero: 0,1,2,3...
integers are whole numbers with negatives: ...-3,-2,-1,0,1,2,3...
rational numbers are any numbers that can be expressed as fractions:
2/3, 5, -3, -12/3,4,5,0....
irrational number are numbers that can't be expressed as fractions, which means that they are never-ending decimals.
Hope this helps!
