Evaluate the expression 43 ÷ (7 − 3) × 2.
Answer: 21.5
Step-by-step explanation:
The order of operations are:
1) Parenthesis and Brackets
2) Exponents
3) Multiplication and Division (from left to right)
4) Addition and Subtraction (from left to right)
Parenthesis are first so let's solve them first
43 ÷ (7 − 3) × 2
43 ÷ (4) × 2
Now we only have division and multiplication
So we must do this from left to right, starting by 43 ÷ 4
43 ÷ 4 × 2
10.75× 2
Finally, multiply
10.75× 2

Answer:
C. f(x) > g(x) for x > 2
Step-by-step explanation:
Using a graph is probably the easiest way to compare an exponential function with a polynomial function. There are no algebraic methods for finding points of intersection. ("Trial and error," or "table of values" will work.)
A graph of these two functions shows f(x) > g(x) except on the interval [1, 2]. That is, f(x) > g(x) for x > 2.
Which of the following statements are TRUE about the normal distribution? Check all that apply.
a. A z-score is the number of standard deviations a specific data value is from the mean of the distribution.
b. The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean.
c. A data value with z-score = -1.5 is located 1.5 standard deviations below the mean.
d. The mean corresponds to the z-score of 1.
e. The area to the left of a z-score plus the area to the right of that same z-score will always equal 1.
Using the normal distribution, it is found that statements a, b, c and e are correct.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.Hence, only statement D is false, as the mean corresponds to z-score of 0.

Solve the equation 25z2 − 140 = 29 by using square roots.

The probability that a meal at a restaurant is overcooked is 10%. Estimate the probability that exactly 1 of the next 2 meals is overcooked.
Answer:
The probability that exactly 1 of the next 2 meals is overcooked = 3.34%
Step-by-step explanation:
The probability that a meal at a restaurant is overcooked is 10%
The probability that exactly 1 of the next 2 meals is overcooked = out of 3 meals 1 meal is overcooked of 10%
= 1 × 3 × 10%
= 10 × 3 %
= 3.34 %
Answer: 18.1%

Annabelle uses models to compare two decimal numbers. She says 0.24 is greater than 0.4 because 24 > 4.
A square partitioned into one hundred equal parts with twenty four parts shaded. To the right is a square partitioned into ten equal parts with four parts shaded.
Which of these explains Annabelle's mistake?
A. Annabelle incorrectly shaded the models. She should shade six more tenths.
B. Annabelle incorrectly counted the number of shaded parts in the models. She should compare 3 shaded parts to 4 shaded parts.
C. Annabelle incorrectly compared hundredths to tenths. She should compare 24 hundredths to 40 hundredths.
D. Annabelle incorrectly compared tenths. She should compare 4 hundredths to 4 hundredths.
Answer:
C

The height of a projectile that is thrown upward from ground level with an initial velocity of 98 meters per second can be modeled by the equation h = −4.9t2 + 98t, where h is the height in meters and t is the elapsed time in seconds. Find the time it takes for the projectile to hit the ground
Answer:
20 seconds
Step-by-step explanation:
The time taken by projectile to hit the ground is 20 second.
What is Quadratic equation?The polynomial equations of degree 2 for a single variable of type f(x) = ax2 + bx + c = 0, where a, b, c, ∈ R, and a ≠ zero, are known as quadratic equations. The leading coefficient is referred to as "a," and the absolute term of the quadratic equation is referred to as "c." The roots of the quadratic equation (α, β). are the values of x that satisfy the equation.
Given initial velocity of a projectile = 98 m/s
equation h = -4.9t² + 98t
where t = time and h = height of projectile,
time taken by projectile to hit the ground,
where h = 0
equation will be
-4.9t² + 98t = 0
4.9t² = 98t
4.9t = 98
t = 98/4.9
t = 20 second
Hence time taken is 20 second.

The graph describes the number of students in each classroom during the first block at a high school.
Please no links.
What percentage of the class have at least 21 students first block.
Answer: 70%
Step-by-step explanation:
Not sure if this is correct but according to the red numbers there is a total of 20 classes. Looking at how many of these classes have 21 or more students we can see that the last three bars contain classes of 21 or more students. The last three bars contain a total of 14 of the 20 classes.
14/20 = 0.7 = 70%
meaning 70% of the classes contain at least 21 students.

Step-by-step explanation:
You volunteer to help drive children at a charity event to the zoo, but you can fit only 6 of the 15 children present in your van How many different groups of 6 children can you drive?
However if you are asking how many different combinations, there can be 5005 different combinations.
Answer:
2 different groups of 6 children.
Step-by-step explanation:
There are 15 children you need to bring. You can fit 6 children in each van.
One van : 6 children
Two vans : 12 children
Three vans : 18 children
If you take two vans, that will take 12 children. But you need to fit 15.
If you take three vans, that will take 18 children. This is more than enough.
15 children - 6 = 9 children
Thats one group with 9 children left to take
9 children - 6 = 3 children
Thats two groups with 3 children left to take
3 children - 6 = -3.
This doesn't work. In this case, there will be 3 more empty seats in the last group.
Since the question asks how many groups of 6 children you can drive. It would be two. Becuase there are 2 groups of 6 and one of 3.

The height of a triangle is 4 feet less than the length of its base, b. The area of the triangle is 30 square feet.
Find the base and the height of the triangle...
.
Answer:
base(b)=10 and height(h)=6
Step-by-step explanation:
From the question,
base(b)=x feet
height(h)=(x-4) feet
Area(A)=30 square feet
Now,
We know,
Area of triangle(A)=1/2*b*h
or, 30=1/2*x*(x - 4)
or, 30=1/2*x^2 -4x
or, 30*2=x^2 -4x
or, 60=x^2 -4x
or, 0 = x^2 -4x -60
or, 0 = x^2 +6x - 10x -60
or, 0 = x(x + 6) -10(x + 6)
or, 0 = (x+6) (x-10)
Either,
x+6=0. or, x-10=0
or,x= -6. or, x= 10
Since, the base of the triangle can not be negative number then, x≠ -6feet but x=10feet
Lastly,
Height(h)=X - 4
=10 - 4
=6 feet
