A.4,000
B.5,000
C.5,4000
D.5,200
Answer:
5,000
Step-by-step explanation:
it cant be 400 because the 4 in 5,421 is going to turn into a zero and everything behind that zero is a 0 as well and the thousand place is before the 0 so it stays the same
There are 21 bags of pears on a market stall.
The mean number of pears in each bag is 8. The table shows the number of pears in 20 of the bags.
Calculate the number of pears in the 21st bag.
Numbers of
pears:
Frequency:
6 2
7 6
8 9
9 1
10 2
Answer:
13 pears in the 21st bag
Step-by-step explanation:
mean = total number of pears/total number of bags
8 = x/21
x = 168
number of pears in 20 bags = (6 x 2) + (7 x 6) + (8 x 9) + (9 x 1) + (10 x 2)
= 155
number of pears in the 21st bag = 168 - 155
= 13

For the function f(x) = 3x + 2, find x such that f(x) = 14.
Answer:
x = 4
Step-by-step explanation:
To find x, plug in 14 into the function
f(x) = 3x + 2
14 = 3x + 2
Solve for x
14 = 3x + 2
12 = 3x
4 = x
So, the answer is x = 4
Which diagrams show XY tangent to circle C? Check all that apply
Answer:
middle and right pictures are correct answer
Step-by-step explanation:
answer attached
The Figure 2 and 3 shows that XY tangent to circle C.
What is Tangent on circle?Tangent is a line that touches the circle and passes through at a touching point.
Need to prove that xy is a tangent line on the circle.
The circle of radius r and center z.
Sine the tangent of the circle and radius of the circle meet at 90 degrees.
Hence, a right-angle triangle is formed so we can apply the Pythagoras theorem.
Here,
xz = 7 cm
xy = 10 cm
Then
10² = 7² + b²
b² = 100 - 49
b² = 51
Hence, the first one doesn't show the XY tangent to circle C.
Similalry for the rest two figures,
When a segment is tangent to a circle, it is perpendicular to the radius.
Therefore, Figure 2 and 3 shows that XY tangent to circle C.

In a large company, the proportion of employees who were promoted during the last year was 0.10. If 100
employees were chosen from this company randomly, what is the probability that at least 15 of them were
promoted during the last year?
O 0.5
O 0.4525
O 0.0475
O 0.9525
Answer:
0.0475
Step-by-step explanation:
We use the binomial approximation to the normal to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Normal probability distribution
Problems of normally distributed distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].
In a large company, the proportion of employees who were promoted during the last year was 0.10.
This means that [tex]p = 0.1[/tex]
100 employees
This means that [tex]n = 100[/tex]
Mean and standard deviation:
[tex]\mu = E(X) = np = 100*0.1 = 10[/tex]
[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{100*0.1*0.9} = 3[/tex]
What is the probability that at least 15 of them were promoted during the last year?
This is [tex]P(X \geq 15)[/tex], which is 1 subtracted by the pvalue of Z when X = 15. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{15 - 10}{3}[/tex]
[tex]Z = 1.67[/tex]
[tex]Z = 1.67[/tex] has a pvalue of 0.9525
1 - 0.9525 = 0.0475.
0.0475 is the answer.
Find 8 1/3% of 72.
Answer:
6
Step-by-step explanation:
8⅓% of 72
Change 8⅓% to an improper fraction, to get.
25/3% × 72
= (25/3)÷(100)×72
= (25/3)×(1/100)× 72
= (25/300) × 72
= 1800/300
= 6
The value of [tex]8\frac{1}{3}[/tex]% of 72 is 600.
Given that, [tex]8\frac{1}{3}[/tex]% of 72.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Now, [tex]8\frac{1}{3}[/tex]% of 72
25/3 × 72
= 25 × 24
= 600
Therefore, the value of [tex]8\frac{1}{3}[/tex]% of 72 is 600.

The number of microscopic organisms in a petri dish grows exponentially with time. The function P below models the number of organisms after growing t days in the petri dish. Based on the function, which of the following statements is true?
P(t) = 60(3)^t/2
A. the predicted number of organisms in the dish triples every two days
B. The predicted number of organisms in the dish doubles every three days
C. The predicted number of organisms in the dish triples every day
D. The predicted number of organisms in the dish doubles every day
Answer:
A
Step-by-step explanation:
Given
P(t) = 60 [tex](3)^{\frac{t}{2} }[/tex]
Then
P(1) = 60 × [tex]3^{\frac{1}{2} }[/tex] = 60[tex]\sqrt{3}[/tex]
P(2) = 60 × 3 = 180
P(3) = 60 × [tex]3^{\frac{3}{2} }[/tex] = 60 ×[tex]\sqrt{3^{3} }[/tex] = 60 × 3[tex]\sqrt{3}[/tex] = 180[tex]\sqrt{3}[/tex]
P(4) = 60 × 3² = 60 × 9 = 540
P(5) = 60 × [tex]3^{\frac{5}{2} }[/tex] = 60 × [tex]\sqrt{3^{5} }[/tex] = 60 × 9[tex]\sqrt{3}[/tex] = 540[tex]\sqrt{3}[/tex]
P(6) = 60 × 3³ = 60 × 27 = 1620
From these 6 results we see that
P(3) = 3 × P(1)
P(4) = 3 × P(2)
P(5) = 3 × P(3)
P(6) = 3 × P(4)
The predicted number of organisms triples every 2 days → A
