Answer: 1/2
Step-by-step explanation:
55 is close to 50
99 is close to 100
55/99 is close to 50/100 = 1/2
Using a calculator, 55/99 = 0.556 approximately which rounds to 0.5 = 1/2
Answer:
1/2
Step-by-step explanation:
55/99 = 0.555
0 = 0
1/2 = 0.5
1 = 1
1 1/2 = 1.5

Answer:
First box is 7x + 21, because when you distribute, you are multiplying the term on the outside of the paranthesis with the term(s) on the inside of the paranthesis.
Second box is 21 + 7x, because the communitive property is basically the same except the terms may be flipped. (Nothing else is different, all terms and signs stay the same, and has the same product/answer.)

When you multiply or divide a positive and a negative number you get a _________
Answer:
You also have to pay attention to the signs when you multiply and divide. There are two simple rules to remember: When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive.

The amount of cleaning solution a company fills its bottles with has a mean of 33fl oz and a standard deviation of 1.5fl oz The company advertises that these bottles have 32fl oz, of cleaning solution.
Answer:
Mean: 30 mL
Standard Deviation: 45mL
Step-by-step explanation:
The area beneath the normal density curve is separated into three regions by the values
and
. Set the mean of the normal density curve to 6.4, the standard deviation to 0.7, and the -value
of
to 6.7. First, determine the value of the area to the right of .
Place
so that it equally divides the area to the left of
. What is the -value
of ?
The value of the area to the right of X > 6.7 calculated from the normal distribution principle is 0.334
Given the Parameters :
Mean, μ = 6.4Standard deviation, σ = 0.7X = 6.7Using the Zscore formula for a normal distribution :
Zscore = (X - mean) / standard deviationThe Zscore, when X = 6.7
Zscore = (6.7 - 6.4) / 0.7 = 0.4286The area to the right of the distribution :
P(Z > 0.4286) = 1 - P(Z < 0.4286)Using a normal distribution table or calculator :
P(Z > 0.4286) = 1 - 0.66589 = 0.334Therefore, the probability value of P(X < 6.7) is
P(Z > 0.4286) = 0.334Learn more :https://brainly.com/question/8165716

In which number is the value of the 5 ten times greater than the value of the 5 in 654,321? 658,321 536,401 65,892 58
Answer:
536,401
Step-by-step explanation:
the 5 is in the ten thousands column in 654,321. you have to times the number by ten to see what column it would be in, 6,543,210. The 5 is now in the hundred thousands column. The only number there with the 5 in in the hundred thousands column is 536,401.
find the difference -156-(-45)
Answer:
-201
Step-by-step explanation:
a negative minus a negative is like adding, but keeping the same sign.
so we can do 156+45, and we get 201.
now we put the negative sign back.

(x, y) → (x + 3, y + 6)one of the root of the quadratic equation x²-(4+p)x+12=0 is three time the other find the root of the equation
Answer:
it should be p=14,x=16,12
The roots of the equations are 2 and 6.
What is a quadratic equation?The equation of the form ax² + bx +c is known as a quadratic equation.
Given that, the quadratic equation is x² - (4 + p)x + 12= 0.
Let the roots of the quadratic equation be a and b.
If the coefficient of x² is 1 in a quadratic equation, then the coefficient of x is equal to the sum of the roots and the constant term is equal to the product of the roots.
Therefore,
a + b = -(4 + p) (1)
ab = 12 (2)
Given that, one root is three times the other, so, let a = 3b and substitute it into equation (2)
3b(b) = 12
3b² = 12
b² = 4
b = 2
Therefore, the value of a is:
a= 3(2)
a = 6
Hence, the roots of the equations are 2 and 6.
