The expense of 1.5 lbs of bananas and 1 gallon of apple juice, according to the provided statement, is $7.45.

Multiplication is one of the four basic operations in mathematics, along with adding, subtracting, and division. Multiply in mathematics refers to the continual adding of sets of identical size.

The cost of 1.5 lb of bananas can be found by multiplying the price per pound by the number of pounds:

Cost of 1.5 lb of bananas = 1.5 x $1.97 = $2.96 (rounded to the nearest cent)

The cost of 1 gallon of apple juice is $4.49.

So, the total cost of 1.5 lb of bananas and 1 gallon of apple juice is:

Total cost = Cost of bananas + Cost of apple juice

Total cost = $2.96 + $4.49

Total cost = $7.45

Therefore, the cost of 1.5 lb of bananas and 1 gallon of apple juice is $7.45.

Answer:

Step-by-step explanation:

First, find out how many half-lives have passed. Divide the number of minutes by the length of a half-life. 34÷17=22 half-lives have passed. Now figure out how much praseodymium will be left after 2 half-lives have passed. Multiply the starting amount of praseodymium by 12 a total of 2 times. 56 x 1/2 x 1/2 = 14 That calculation could also be written with exponents:56x (1/2)^2=14 After 2 half-lives, the amount of praseodymium left will be 14 grams.

Assuming the half-life of a radioactive kind of praseodymium is 17 minutes.The amount that will be left after 34 minutes is 14g.

Since 34 minutes is exactly 2 half-lives of 17 minutes.

Hence, remaining amount will then be:
Remaining amount= (1/2)×(1/2) = (1/2)² of the initial amount

Final amount:

Final amount = (1/2)² (56g)

Final amount=0.25 (56g)

Final amount = 14 g

Inconclusion  the half-life of a radioactive kind of praseodymium is 17 minutes.The amount that will be left after 34 minutes is 14g.

Step-by-step explanation:

confidence interval: This tells us the degree of certainty or uncertainty that is existent in a sampling method.

To construct a 95% confidence interval for the population mean cholesterol level, we can use the following formula:

CI = x ± t*(s/√n)

where x is the sample mean, s is the sample standard deviation, n is the sample size, and t is the t-value from the t-distribution with n-1 degrees of freedom and a confidence level of 95%.

Substituting the given values, we have:

CI = 224 ± t*(12/√21)

Using a t-table with 20 degrees of freedom (since n-1=20), we find that the t-value for a 95% confidence interval is approximately 2.086.

Thus, the confidence interval is:

CI = 224 ± 2.086*(12/√21)

CI = (219.60, 228.40)

Therefore, the answer is option (c) (219.60, 228.40).

The function will have a period of π and an amplitude of 3.

To graph the function y = 3cos(2x + π/2) - 2 for 0 ≤ x ≤ 2π, we can analyze its key components and then plot the points accordingly.

The period of the function can be determined by considering the coefficient of x in the argument of the cosine function. In this case, the coefficient is 2, which means the period is given by 2π/2 = π.

The amplitude of the function is the coefficient in front of the cosine function, which is 3 in this case.

To plot the graph, we can start by selecting some x-values within the range 0 ≤ x ≤ 2π and evaluate the corresponding y-values using the given function.

When x = 0:

y = 3cos(2(0) + π/2) - 2 = 3cos(π/2) - 2 = 3(0) - 2 = -2

When x = π/4:

y = 3cos(2(π/4) + π/2) - 2 = 3cos(π/2 + π/2) - 2 = 3cos(π) - 2 = -5

When x = π/2:

y = 3cos(2(π/2) + π/2) - 2 = 3cos(π + π/2) - 2 = 3cos(3π/2) - 2 = -2

When x = 3π/4:

y = 3cos(2(3π/4) + π/2) - 2 = 3cos(3π/2 + π/2) - 2 = 3cos(2π) - 2 = 1

When x = π:

y = 3cos(2π + π/2) - 2 = 3cos(5π/2) - 2 = 3(0) - 2 = -2

When x = 5π/4:

y = 3cos(2(5π/4) + π/2) - 2 = 3cos(5π/2 + π/2) - 2 = 3cos(3π) - 2 = -5

When x = 3π/2:

y = 3cos(2(3π/2) + π/2) - 2 = 3cos(3π + π/2) - 2 = 3cos(5π/2) - 2 = -2

When x = 7π/4:

y = 3cos(2(7π/4) + π/2) - 2 = 3cos(7π/2 + π/2) - 2 = 3cos(4π) - 2 = 1

When x = 2π:

y = 3cos(2(2π) + π/2) - 2 = 3cos(4π + π/2) - 2 = 3cos(9π/2) - 2 = -2

Based on these points, we can plot the graph of the function over the given range 0 ≤ x ≤ 2π. The graph will have a period of π and an amplitude of 3. It will oscillate between the values -2 and 1.

a. Statement and Proof of Fermat's Little Theorem:

Fermat's Little Theorem concerns primes and integers in number theory.

Fermat's Little Theorem asserts that when a positive integer a, which is not divisible by a prime number p, is raised to the power of (p-1), the resultant remainder upon division by p will be 1.

So it will be: \(\\ a ^(^p^-^1) = 1 (mod p)\)

The Evidence has been gathered to substantiate this claim is:

If a is divisible by p, then a can be written as the product of p and a positive integer k. Expressing the value of a to the power of p minus one in relation to k and p can be achieved through utilization of the equation (k multiplied by p) raised to the power of p minus one.

By performing a simplification of the given expression, we can obtain the outcome where "a" to the power of "p" minus one is equivalent to "k" to the power of "p" minus one times "p" to the power of "p" minus one.

The unknown measure are m∠C = 64°, a ≈ 19.16 and c ≈ 18.11.

As the triangle is not a right angled triangles, then neither Law of Cosines, or the Pythagorean Theorem and trigonometric ratios will be used, as all the theory are only possible when triangle is right angled and for law of cosines 2 sides are to be known is must.

Here, we can only use Law of Sines  that is:

\($ \rm \frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}\)

A = angle A

a = length of side a

B = angle B

b = length of side b

C = angle C

c = length side c

Then leys find measure of angle first using angle sum property:

m∠C = 180° - (72° + 44°)

m∠C = 180° - 116°

m∠C = 64°

As per the Law of Sines, tο find the length οf sides οf triangle say △ABC, we can write as;

\($ \rm \frac{\sin (72^{\circ})}{a}=\frac{\sin (44^{\circ})}{14}=\frac{\sin (64^{\circ})}{c}\)

Lets solve each one by one:

\($ \rm \frac{\sin (72^{\circ})}{a}=\frac{\sin (44^{\circ})}{14}\)

a × sin(44°) = 14 × sin(72°)

\($ \rm a=\frac{14 \times \sin (72^{\circ})}{\sin (44^{\circ})}\)

\($ \rm a=\frac{14 \times 0.9511}{0.6947}\)

\($ \rm a=\frac{13.3154}{0.6947}\)

a ≈ 19.16

Then for c:

\($ \rm \frac{\sin (64^{\circ})}{c} = \frac{\sin (44^{\circ})}{14}\)

c × sin(44°) = 14 × sin(64°)

\($ \rm c=\frac{14 \times \sin (64^{\circ})}{\sin (44^{\circ})}\)

\($ \rm c=\frac{14 \times 0.898794}{0.6947}\)

Poisson distribution is used to describe the arrival rate and exponential distribution is used to describe the service time. The probability that the inspector will be idle is 0.1246. Given information: λ = 2 vehicles/hour

μ = 15 minutes per vehicle

= 0.25 hours per vehicle

To find out the probability that the inspector will be idle, we need to use the formula for the probability that a server is idle in a queuing system. Using the formula for probability that a server is idle in a queuing system: where

λ = arrival rate

μ = service rate

n = the number of servers in the system Given, there is only one lane and one inspector. Hence, the probability that the inspector will be idle is 0.2424. In queuing theory, Poisson distribution is used to describe the arrival rate and exponential distribution is used to describe the service time.

In this problem, vehicles arrive at the rate of 2 per hour and the inspector can inspect the vehicle in an average of 15 minutes which can be written in hours as 0.25 hours. To find out the probability that the inspector will be idle, we need to use the formula for the probability that a server is idle in a queuing system. In this formula, we use the arrival rate and service rate to find out the probability that the server is idle. In this case, as there is only one inspector and one lane, n = 1. Using the formula, we get the probability that the inspector will be idle as 0.2424.
