a number increased by 9 is 13
Answer:
4
Step-by-step explanation:
To find the number you have to reverse the equation
Let us call the number "x"
x + 9 = 13
So to find x we flip the equation
13 - 9 = x
Solve it
4 = x
So the missing number is 4

Answer: 5/12
Step-by-step explanation:
Answer:
5/12
Step-by-step explanation:
We are going to change both number so they have the same denominators.
1/4x3/3= 3/12
2/3x4/4=8/12
Once we changed the number we are going to subtract the numbers.
8/12-3/12=5/12
We can't simplify 5/12 so the answer is 5/12.

Step-by-step explanation:
[tex] \frac{9}{x} = \frac{x}{4} \\ \\ x \times x = 9 \times 4 \\ \\ {x}^{2} = 36 \\ \\ x = \pm\sqrt{36} \\ \\ x = \pm 6 \\ \\ x = - 6, \: \: x = 6[/tex]
Nutritionists measured the sugar content (in grams) for 32 drinks at Jake's Java
coffee shop. The drinks had a mean sugar content of 18g and a standard
deviation of 5g, and the distribution was roughly symmetric.
Question 1: Grande Mocha Cappuccino at Jake's Java contains 14 g of sugar.
Calculate the standardized score (z-score) for the Grande Mocha Cappuccino.
Answer:
[tex]z = -0.8[/tex]
Step-by-step explanation:
Given
[tex]n = 32[/tex] --- samples
[tex]\mu = 18g[/tex] --- mean
[tex]\sigma =5g[/tex] --- standard deviation
[tex]x = 14g[/tex] --- observed value
Required
Find the standardized score
This is calculated as:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
So:
[tex]z = \frac{14g -18g}{5g}[/tex]
[tex]z = \frac{-4g}{5g}[/tex]
[tex]z = \frac{-4}{5}[/tex]
[tex]z = -0.8[/tex]
The standardized score is -0.8

8 + 12n – 4n – 7 Another problem pls dont troll or i will report you :)
Answer:
Step-by-step explanation:
Do u see any similarities between the numbers? Both 12 and -4 have a variable(N). 8 and -7 dont have a variable, so u have to calculate them individually.
One thing to remember is just because there is a minus sign(-) or a plus sign(+) does not mean its addition or subtraction. its the value of the number. the sign to the left of the number is its value. so left of 12 is plus(+), so its a positive. left of 4 is a minus sign(-) so its a negative 4. lastly, left of 7 is minus sign(-), which means its negative 7. now u add.
lets add the variables first:
12n + (-4n) = 8n
add the regular numbers:
8 + (-7) = 1
so its 8n + 1

Does it lie inside, outside, or on the circle?
Answer:

Lets find the distance from (7, 2) to the center of the circle:
[tex]d = \sqrt{(7 - 4)^2 + (2 - 0)^2} = \sqrt{9+4} = \sqrt{13} < 5[/tex]Since d < 5, the point (7, 2) lies inside the circle

Pythagorean theorem and Converse; find the value of x.
Answer:
x = 12.206555
Step-by-step explanation:
10^2 + 7^2 = 149
Sqrt(149) = 12.206555 = x
x ≈ 12.2, 12
Therefore, the value of the hypotenuse [tex]x[/tex] is [tex]12[/tex].
What is the pythagorean theorem?
The Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.
Here given that,
[tex]B=7,P=10[/tex]
As we know,
[tex]H^2=B^2+P^2[/tex]
Substitute the given values in the formula is
[tex]x^2=(7)^2+(10)^2\\\\x^2=49+100\\\\x^2=149\\\\x=\sqrt{149}\\\\x=12[/tex]
Hence, the value of the [tex]x[/tex] is [tex]12[/tex].
