A certain fish grows so that after t years of life its length is given by L(t) = 9 − 1/5t inches. Calculate the average rate of growth over the first year of life.

Answers

Answer:

Step-by-step explanation:

Given the length of a fish after t years modeled by the equation

L(t) = 9 − 1/5t

The average rate of growth is expressed as;

dL/dt = -1/5 (differential of a constant is zero)

Hence the average rate of growth  over the first year of life is -1/5 in/year

Given triangle MAT is an isosceles triangle and point H is the midpoint if MT. Prove triangle MHA is congruent to triangle THA

Answers

Answer:

There is everything in the image

The Side-Angle-Side postulate is satisfied. Then the triangle ΔMHA and ΔTHA are congruent with each other.

What is the triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In an isosceles triangle, the two legs of the triangle are congruent and their opposite angles too.

A triangle MAT is an isosceles triangle and point H is the midpoint of MT.

In triangle ΔMHA and ΔTHA, we have

AH = AH (Common sides)

MH = HT (H is the midpoint of MT)

∠AMH = ∠ATH (Isosceles angles)

The Side-Angle-Side postulate is satisfied. Then the triangle ΔMHA and ΔTHA are congruent with each other.

Liz is taking guitar lessons and practices every night. Yesterday, she played a total of 40 chords in 8 minutes. Today she will play chords for 5 minutes. If she plays at the same rate, how many chords will Liz play today?

Answers

Answer:the answer is 25

Step-by-step explanation:

40 divided by 8 = (chords played per minute)

5 times (chords played per minute and you get your answer

Liz will play a total of 25 chords in 5 minutes today which is determined by the ratio.

What is Ratio?

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that Liz played a total of 40 chords in 8 minutes.

Let's assume she plays a total of x chords in 5 minutes.

According to the given question, we can write the ratio as:

40 chords : 8 minutes =  x chords : 5 minutes

⇒ 40 / 8 = x / 5

Apply the cross-multiplication operation,

⇒ 8x = 40 × 5

Apply the multiplication operation,

⇒ 8x = 200

⇒ x = 200/8

Apply the division operation to get the answer

⇒ x = 25

Therefore, she will play a total of 25 chords in 5 minutes.

CallmeCarson lol

Answer:

860$

Step-by-step explanation:

In order to find the answer to this question you need to multiply the amount of hours Carson worked to the amount of days he worked and then you need to multiply that by the amount he gets paid per hour.

[tex]21.50 = ph[/tex]

[tex]hours=8[/tex]

[tex]days = 5[/tex]

[tex]8\times5=40[/tex]

So he worked 40 hours a week

[tex]40 \times21.50 = 860[/tex]

Therefore Mr.Carson has made 860$ that week.

Answers

Answer:

[tex]Earnings = 308.75[/tex] ---- (a)

[tex]Earnings = 300 + 0.05x[/tex] -- (b)

Step-by-step explanation:

Given

[tex]Base\ Salary = 300[/tex]

[tex]Commission = 5\%[/tex]

Solving (a): Sales of $2175 in a week.

His total earnings is calculated as thus:

[tex]Earnings = Base\ Salary + Commission * Sales[/tex]

[tex]Earnings = 300 + 5\% * 2175[/tex]

[tex]Earnings = 300 + 108.75[/tex]

[tex]Earnings = 308.75[/tex]

Solving (b): Sales of $x in a week.

His total earnings is calculated as thus:

[tex]Earnings = Base\ Salary + Commission * Sales[/tex]

[tex]Earnings = 300 + 5\% * x[/tex]

Convert percent to decimal

[tex]Earnings = 300 + 0.05 * x[/tex]

[tex]Earnings = 300 + 0.05x[/tex]

Suppose a population grows according to a logistic model with initial population 1000 and carrying capacity 10,000. If the population grows to 2500 after one year, what will the population be after another three years?

Answers

Answer:

7500

Step-by-step explanation:

1 year= 2500

3 years= x

So we got

2500 × 3 = 7500

The population after another three years will be 15,625.

What is an exponent?

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

y = a(b)ˣ

Assume a populace becomes as per a strategic model with starting populace of 1,000 and conveying limit of 10,000.

If the population grows to 2500 after one year. Then the increasing factor is given as,

b = 2,500 / 1,000

b = 2.5

Then the equation is given as,

y = 1,000 × (2.5)ˣ

Then the population after another three years will be given as,

y = 1,000 × (2.5)³

y = 1,000 × 15.625

y = 15,625

The population after another three years will be 15,625.

a. 0.860
b. 0.802
c. 0.057
d. 0.198

Answers

Answer:

The answer to this question would normally be, 85.96%, though that isnt an answer choice so the closest thing to it would most likely be answer choice A.

Using the binomial approximation to the normal, it is found that:

0.86 probability that at most 60 say yes, given by option a.

------------------------

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value is:

[tex]E(X) = np[/tex]

The standard deviation 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 z-score 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. Each z-score has a corresponding p-value.The p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.The probability that the measure is greater than X is 1 subtracted by the p-value.

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], if [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex].

----------------------------

64% use services, thus, [tex]p = 0.64[/tex]87 people are sampled, thus, [tex]n = 87[/tex]

The mean and standard deviation are given by:

[tex]\mu = E(X) = np = 87(0.64) = 55.68[/tex]

[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{87(0.64)(0.36)} = 4.4771[/tex]

Using continuity correction, the probability that at most 60 use is [tex]P(X \leq 60 + 0.5) = P(X \leq 60.5)[/tex], which is the p-value of Z when X = 60.5, thus:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{60.5 - 55.68}{4.4771}[/tex]

[tex]Z = 1.08[/tex]

[tex]Z = 1.08[/tex] has a p-value of 0.86.

Thus, 0.86 probability that at most 60 say yes, given by option a.

Work out the price of the dessert after the increase.

Answers

Answer:

Step-by-step explanation:

The question requires the price of the desert after the increase

price of the dessert after the increase is £4.59

Price before increase = £4.25

Percentage increase = 8%

Amount of increase = 8% of 4.25

= 8/100 × 4.25

= 0.08 × 4.25

= £0.34

Price after increase = Price before increase + Amount of increase

= £4.25 + £0.34
