Answer: 14.90$ weekly deduction

Step-by-step explanation:

Answer:

$14.9 deduction

Step-by-step explanation:

Silvaro borrowed $89.40 from hsi brother

Silvaro decided that he will pay him back the money in six months of allowance.

Therefore the effect of the payment in his bank account can be calculated as follows.

= $89.40/6

= $14.9

Hence the payment will have a deduction of $14.9 from his monthly bank account

Answer: The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. It's a fundamental relation in Euclidean geometry among the three sides of a right triangle.

Step-by-step explanation:

Answer:

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs.

Answer:

0.873 = 87.3% probability that an athlete tests negative and is not a user of an illegal drug

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Not a user of an illegal drug.

Event B: Tests negative.

The test for this drug is 90% accurate for non-drug users (this means there is a 90% chance the test comes back negative if the person is a non-user)

This means that [tex]P(B|A) = 0.9[/tex]

It is estimated that 3% of the athletes competing in a large tournament are users of an illegal drug to enhance performance.

So 100 - 3 = 97% probability that the athlete does not use the drug, so [tex]P(A) = 0.97[/tex]

What is the probability that an athlete tests negative and is not a user of an illegal drug

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

[tex]P(A \cap B) = 0.9*0.97 = 0.873[/tex]

0.873 = 87.3% probability that an athlete tests negative and is not a user of an illegal drug

Answer:

nth term = 1000×1.2ⁿ⁻¹

Step-by-step explanation:

The explicit rule for the given geometric sequence is aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹

A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant.

Given that, in two years the deer population in a state forest was 1,200. In year 4, the population was 1,728,

Therefore,

a₄ = 1728 and a₂ = 1200

We have two terms of the GP, therefore, finding r,

r² = 1728 / 1200 = 1.44

r = 1.2

Therefore,

a₁ = a₂r¹⁻²

= 1200r⁻¹ = 1200/r

= 1200 / 1.2 = 1000

Therefore, the formula will be = aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹

Hence, the explicit rule for the given geometric sequence is aₙ = a₁rⁿ⁻¹ = 1000 x 1.2ⁿ⁻¹

The logarithmic expressions are log6 with base 3 and log5 with base 4.

What is logarithmic function?

It is the inverse of the exponential functions. It is equal to y=㏒x.

A) log 8 with base 3=log8/log3=0.903089987/0.4771212547=1.8927

B) log 6 with base 3=log6/log3= 0.77815125038/0.4771212547=1.6309

C) log 5 with base 4=log5/log4=0.69897000433/0.60205999132=1.1609

D) log 32 with base 2=log32/log2=1.50514997832/0.30102999566=5

IQR is 11.

The first quartile, second quartile and the interquartile range are used to measure the variation of data. Median is a measure of central tendency. Median is the number at the center of the dataset.

Q1 = 1/4 x (n + 1)

1/4 x 8 = 2nd number = 3

Q2 = 1/2 x (n + 1)

1/2 x 8 = 4th number = 12

Q3 = 3/4 x (n + 1)
