Each t-shirt costs $15, and each pair of gym shorts costs $16.

Let's call the cost of each t-shirt "x". Then the cost of each pair of gym shorts is x + $1.

We know that the total cost of the t-shirts is 5 * x, and the total cost of the gym shorts is 2 * (x + $1).

We also know that the total cost of all items is $107, so we can write an equation to represent this information:

5x + 2(x + $1) = $107

5x + 2x + 2 = $107

7x + 2 = $107

7x = $105

x = $15

So, each t-shirt costs $15, and each pair of gym shorts costs $15 + $1 = $16.

The probability of the teacher selecting one green popsicle can be calculated by dividing the number of green popsicles in the box (4) by the total number of popsicles in the box (24). The probability of selecting one green popsicle is: P(green) = 4/24 = \(1/6 ≈ 0.1667\)

This means that there is a 16.67% chance of the teacher selecting a green popsicle from the box. To describe this simple event, we can say that the teacher will randomly select one popsicle from the box and the probability of that selected popsicle being green is 1/6.

If the teacher repeated this experiment many times (selecting one popsicle at a time), we would expect to see a green popsicle selected approximately once in every six trials.

It's important to note that this probability assumes that all the popsicles in the box are equally likely to be selected and that the teacher is selecting the popsicle at random without any bias or preference towards any specific color.

Answer:

-9a^2+14

Step-by-step explanation:

The $8.78 more interest is owed on $900 for 9 months than 6 months.

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.

(a)

The formula for simple interest:

I = Prt

I(for 9 months) = 900x(2.9/100)(9/12)

I(for 9 months) = $19.575 = $19.58

I(for 6 months) = 900x(2.4/100)(6/12)

I(for 6 months) = $10.8

Difference = $19.58 - $10.8 = $8.78

(b)

From the table: the interest rate from 6 months to 9 months increases by 0.5% after that it increases constantly.

Thus, the $8.78 more interest is owed on $900 for 9 months than 6 months.

Answer:

Step-by-step explanation:

Option A is the correct answer. Ellora wants to accumulate 150,000 in an RRSP by making annual contributions of 5,000 at the beginning of each year. If interest is 5.5% compounded quarterly, calculate how long she has to make contributions.

First, we have to find the interest rate per quarter, which will be
\(5.5% / 4\)= 1.375%.
The formula for the future value of an annuity is: 
\(FV = (C * [(1 + r)^n - 1] / r)\),

For Ellora, \(FV = $150,000, C = $5,000, and r = 1.375%.\)
Substituting these values into the formula gives:
\(150,000 = 5,000 * [(1 + 0.01375)^n - 1] / 0.01375\)
Simplifying this equation gives:
\(30 = [(1.01375)^n - 1]\)

We can solve this using logarithms:
\(ln 30 = ln [(1.01375)^n - 1]\)
\(ln 30 = n * ln 1.01375 - ln 1.01375e^(ln 30) / e^(-ln 1.01375) = n18.202125 = n\)

Therefore, it will take Ellora 18.202125 years to accumulate 150,000 in her RRSP through \($5,000\)annual contributions made at the beginning of each year with interest of \(5.5%\) compounded quarterly.

The negative sign indicates that the boat traveled in the opposite direction of its intended destination, and it traveled a distance of 2.55 miles.

The speed of the motorboat is given as -3.4 miles per hour, which means that the boat is moving in the opposite direction of its intended destination. If we assume that the boat is moving at a constant speed of -3.4 miles per hour for 0.75 hours, we can use the formula:

distance = speed x time

where distance is the distance traveled, speed is the speed of the boat, and time is the time for which the boat travels at that speed.

Plugging in the given values, we get:

distance = -3.4 miles/hour x 0.75 hour

When the water depth is 7 m, the water level in the cone is rising at a rate of 1365/(48π) m/min.

Height of the cone (h) = 7 m

Rate of water filling the cone (dh/dt) = 5 m/min

The rate at which the water level is rising (dh/dt) when the water depth is 7 m.

Let's denote the radius of the cone as r and the volume of the cone as V.

The volume of a cone can be expressed as V = (1/3)πr²h, where π is a constant.

Differentiating both sides of the equation with respect to time (t), we get:

dV/dt = (1/3)π(2r)(dr/dt)h + (1/3)πr²(dh/dt)

The term (1/3)π(2r)(dr/dt)h represents the rate of change of volume concerning the changing radius, and the term (1/3)πr²(dh/dt) represents the rate of change of volume with respect to the changing height.

Since the cone is being filled with water, the rate of change of volume is equal to the rate of water filling the cone. Therefore, dV/dt = 5 m³/min.

Substituting the given values and solving for (dh/dt):

5 = (1/3)π(2r)(dr/dt)(7) + (1/3)πr²(dh/dt)

To solve for (dh/dt), we need to find the value of (dr/dt). Since the cone is assumed to be a right circular cone, the radius (r) and height (h) are related by the equation r = (2/7)h.

Differentiating the equation r = (2/7)h with respect to time (t), we get:

dr/dt = (2/7)(dh/dt)

Substituting this value into the previous equation, we have:

5 = (1/3)π(2r)((2/7)(dh/dt))(7) + (1/3)πr²(dh/dt)

Simplifying and solving for (dh/dt):

5 = (4/7)πr(dh/dt) + (1/3)πr²(dh/dt)

Multiplying through by 21/(4πr):

105/(4πr) = (dh/dt) + (7/(3r))(dh/dt)

Combining like terms:

105/(4πr) = (1 + 7/(3r))(dh/dt)

Finally, solving for (dh/dt):

dh/dt = 105/(4πr)(1 + 7/(3r))

Since the height of the water in the cone is 7 m, we can substitute r = (2/7)(7) = 2 into the equation:

dh/dt = 105/(4π(2))(1 + 7/(3(2)))

Simplifying the equation:

dh/dt = 105/(8π)(1 + 7/6)

dh/dt = 105/(8π)(13/6)

dh/dt = 1365/(48π) m/min

Therefore, when the water depth is 7 m, the water level in the cone is rising at a rate of 1365/(48π) m/min.

The value for X  in the equation is 200.14.

To solve for the value of X in the given equation, let's simplify and solve step by step.

We have:

-0.12 = (x - 238) / 238 + 9.3 / 238

Let's start by simplifying the right-hand side of the equation by finding a common denominator:

-0.12 = (x - 238 + 9.3) / 238

Combining the terms on the numerator of the right-hand side:

-0.12 = (x - 228.7) / 238

Next, let's multiply both sides of the equation by 238 to eliminate the denominator:

-0.12 * 238 = x - 228.7

-28.56 = x - 228.7

To isolate x, we'll add 228.7 to both sides of the equation:

-28.56 + 228.7 = x - 228.7 + 228.7

200.14 = x

Therefore, the value of X is 200.14.

The probability that Ali misses 4 shots out of 25, given that he has a 3-point shooting percentage of 9/10 or 0.9, is approximately 0.1394, or about 13.94%.

The probability of an event occurring is defined by probability. There are numerous real-life scenarios in which we must forecast the outcome of an occurrence.

We can use the binomial distribution to find the probability that Ali misses 4 shots out of 25, given that he has a 3-point shooting percentage of 9/10 or 0.9.

Let X be the number of missed shots out of 25 attempts. Since each shot is either a miss or a make, this is a binomial distribution with n = 25 and p = 1 - 9/10 = 1/10. We want to find P(X = 4), which is:

P(X = 4) = (25 choose 4) * (1/10)⁴ * (9/10)²¹

where "25 choose 4" is the number of ways to choose 4 shots out of 25.

Using a calculator, we can evaluate this expression to find:

P(X = 4) ≈ 0.1394

Therefore, the probability that Ali misses 4 shots out of 25, given that he has a 3-point shooting percentage of 9/10 or 0.9, is approximately 0.1394, or about 13.94%.

p -value = 0.007

Step-by-step explanation:

Step(i):-

Given random sample size 'n' = 45

Mean of the Population = 18.0 c.m

Standard deviation of the Population(S.D) = 0.25 c.m

Mean of the sample = 17.9 c.m

Null hypothesis :-

               H₀ : μ = 18.0 c.m

Alternative Hypothesis:

             H₁ :  μ ≠ 18.0 c.m

Test statistic

  \(Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }\)

 \(Z = \frac{17.9-18 }{\frac{0.25}{\sqrt{45} } } = -2.688\)

|Z| = |-2.688|

|Z| = 2.688≅ 2.7

Step(ii):-

P -value :-

The z-test statistic value = 2.7

P( Z>2.7) = 1- P(Z< 2.7)

                  = 1- ( 0.5+ A(2.7))

                  = 0.5 - A(2.7)

                  = 0.5 - 0.4965

                 = 0.0035

P( Z>2.688)= 0.0035

Given data is two tailed test

2 X P( Z>2.688) = 2 X 0.035 = 0.007

P-value = 0.007

we will choose level of significance ∝=0.05

Since r = √(x² + y²) in Cartesian coordinates, we can substitute it into the equation: x + y = √(x² + y²).

To convert the polar equation rcosθ + rsinθ = 1 into a Cartesian equation, we can use the trigonometric identities cosθ = x/r and sinθ = y/r.

Substituting these identities, we get x + y = r. Since r = √(x² + y²) in Cartesian coordinates, we can substitute it into the equation: x + y = √(x² + y²).

To identify the graph, we can rearrange the equation to form x² + y² = (x + y)², which simplifies to x² + y² = x² + 2xy + y². Canceling out the x² and y² terms, we obtain 2xy = 0.

This equation represents two perpendicular lines, one along the x-axis and the other along the y-axis, intersecting at the origin.
