r = 4s

r = 1/2s + 7

Step 2: Solve for s

Substitution

Step 3: Solve for r

Answer:

s = 2

r = 8

Step-by-step explanation:

subsitution is were you plug in a systerm into the other problem

since they give you R = 4s you take 4s and plug it in were r is in the other equation (subsitution)

so now you have 4s = 1/2s+7

now you want to solve for s so your going to subtract 1/2s from both sides to cancle out the 1/2s --> 4s - 1/2s = 7 --> 3 and 1/2s = 7

now divide both sides by 3 1/2 to get s alone s = 7/3 and 1/2

s = 2

now we have s we take that and plug it into r = 4s

subsitute S as 2  --> r = 4(2)

r = 8

The sampling distribution of a statistic is: c. the distribution of values taken by a statistic in all possible samples of the same sample size.

The sampling distribution of a statistic refers to the distribution of values that the statistic takes on when calculated from all possible samples of the same sample size taken from a population. It represents the variability or spread of the statistic's values across different samples. The sampling distribution is important because it allows us to make inferences about the population parameter based on the observed sample statistic. By understanding the distribution of the statistic, we can estimate the parameter and assess the uncertainty associated with our estimation.

It is possible that a hybrid battery may need to be replaced after driving 100,000 miles, but it is not necessarily a given. The lifespan of a hybrid battery can vary depending on several factors.

The lifespan of a hybrid battery depends on various factors such as the make and model of the car, the age of the battery, driving habits, and the frequency of use. Some manufacturers claim that their hybrid batteries can last up to 150,000 miles or more. However, if the battery is not properly maintained or if the car is driven aggressively, it may degrade more quickly. Furthermore, extreme temperatures can also affect the lifespan of the battery. For example, very cold temperatures can reduce the battery's capacity, while extremely hot temperatures can cause damage to the cells. Therefore, while it is possible that a hybrid battery may need to be replaced after driving 100,000 miles, it is not necessarily a reasonable claim without considering the specific circumstances of the car and battery. It is best to consult with a certified mechanic to evaluate the condition of the battery and determine if replacement is necessary.

Step-by-step explanation:

The domain of A is the set of all possible values of l that would result in a valid area for the rectangle. The width of the rectangle cannot be negative. Hence, we get; w = 6-l > 0⇒ 6 > l > 0∴ The domain of A is [0, 6].

Given that a rectangle has a perimeter of 12m and we need to express the area of the rectangle as a function of the length of one of its sides. The perimeter of a rectangle is given by the formula 2l + 2w where l and w are the length and width of the rectangle respectively.

We are given that the perimeter of the rectangle is 12m.∴ 2l + 2w = 12mOn simplifying, we get; l + w = 6mNow, the area of a rectangle is given by the formula; A = lw Thus, substituting l = 6-w, we get; A = w(6 - w)This is the formula for the area of the rectangle as a function of its length.

The domain of A is the set of all possible values of l that would result in a valid area for the rectangle. The width of the rectangle cannot be negative. Hence, we get; w = 6-l > 0⇒ 6 > l > 0∴ The domain of A is [0, 6]. Hence, this is the answer.

(b) t = 100 : 9999/140000 square units.

(c) Total area under this curve for x ≥ 1 : 1/14 square units.

Given the equation of the curve is,

y = 1/7x³

The area under the given curve from x = 1 to x = t using integration is given by,

A(t) = \(\int_1^t\) y . dx = \(\int_1^t\) (1/7x³) dx = \(-[\frac{1}{14x^2}]_1^t\) = - [(1/14t²) - (1/14)] = -1/14 [(1/t²) - 1]

So, the area when t = 10 is,

A(10) = - 1/14 [1/100 - 1] = -1/14*(-99/100) = 99/1400 square units.

When t = 100 then the area is,

A(100) = - 1/14 [1/10000 - 1] = -1/14*(-9999/10000) = 9999/140000 square units.

The probability that a test revealed that Jared is a carrier but Lucia is not is 1/4

Mendel discovered that genes are inherited as separate, paired units, one from each parent. Its application of mathematics to illuminate observations of natural phenomena.

Given that lucia and jared each have a sibling with cystic fibrosis, but neither lucia nor jared nor their parents have the disease

Mendel theory is a technique used to estimate the probability of getting specific characteristics.

Lucia and Jared have a probability of both carrier and non carrier

If both of them are non carrier then the children born to their family have no chances of getting disease.

If any one of them is carier, then there is a chance of getting one child as a carrier. That is ¼ or the ratio is 1:4

If both of them are carriers then the ratio will be 1:2:1

If Jared is carrier then the probability will be ¼

a. The probability that a randomly selected bottle will have less than 354 ml of beer is approximately 0.3085.

To calculate this probability, we convert the value of 354 ml to a z-score using the formula z = (x - μ) / σ, where x is the value we want to find the probability for (354 ml), μ is the mean (355 ml), and σ is the standard deviation (8 ml). By calculating the z-score, we can then look up the corresponding area under the normal distribution curve using a z-table. The z-score for 354 ml is approximately -0.125, and the corresponding area (probability) is 0.4508. Therefore, the probability of having less than 354 ml is 0.5 - 0.4508 = 0.0492 (or approximately 0.3085 when rounded to four decimal places).

b. The probability that a randomly selected 6-pack of beer will have a mean amount less than 354 ml is approximately 0.0194.

To calculate this probability, we need to consider the distribution of the sample mean. Since we are selecting a sample of size 6, the mean of the sample will have a standard deviation of σ / √n, where σ is the standard deviation of the population (8 ml) and n is the sample size (6). The standard deviation of the sample mean is therefore 8 ml / √6 ≈ 3.27 ml. We can then convert the value of 354 ml to a z-score using the same formula as in part a. The z-score for 354 ml is approximately -0.3061. By looking up this z-score in the z-table, we find the corresponding area (probability) of 0.3808. Therefore, the probability of the mean amount being less than 354 ml is 0.5 - 0.3808 = 0.1192 (or approximately 0.0194 when rounded to four decimal places).

c. The probability that a randomly selected 12-pack of beer will have a mean amount less than 354 ml is approximately 0.0022.

Similar to part b, we calculate the standard deviation of the sample mean for a sample size of 12, which is σ / √n = 8 ml / √12 ≈ 2.31 ml. By converting 354 ml to a z-score, we find a value of approximately -1.08. Looking up this z-score in the z-table, we find the corresponding area (probability) of 0.1401. Therefore, the probability of the mean amount being less than 354 ml is 0.5 - 0.1401 = 0.3599 (or approximately 0.0022 when rounded to four decimal places).

Solution given:

Cos\(\theta_{1}=\frac{10}{17}\)

\(\frac{adjacent}{hypotenuse}=\frac{10}{17}\)

equating corresponding value

we get

adjacent=10

hypotenuse=17

perpendicular=x

now

by using Pythagoras law

Hypotenuse ²=perpendicular²+adjacent ²

substituting value

17²=x²+10²

17²-10²=x²

x²=17²-10²

x²=189

doing square root

\(\sqrt{x²}=\sqrt{189}\)

x=\(3\sqrt{21}\)

now

In I Quadrant sin angle is positive

Sin\(\theta_{1}=\frac{perpendicular}{hypotenuse}\)

Answer:

sin theta = 3 sqrt(21)/17

Step-by-step explanation:

cos theta = adj / hyp

We can find the opp by using the Pythagorean theorem

adj^2 + opp ^2 = hyp^2

10^2 +opp^2 = 17^2

100 + opp^2 = 289

opp^2 = 289-100

opp^2 = 189

Taking the square root

opp = sqrt(189)

opp = 3 sqrt(21)

Since we are in the first quad, opp is positive

sin theta = opp /hyp

sin theta = 3 sqrt(21)/17

Answer:

\(G(17) \approx 1.782\)

Step-by-step explanation:

Let \(\frac{dG}{dt} = t^{-1/2}\) and \(G(3) = -3\), we proceed to find \(G(t)\) by integrating \(\frac{dG}{dt}\) in time:

\(G(t) = \int {t^{-1/2}} \, dt\)

\(G(t) = \frac{t^{1/2}}{\frac{1}{2} } + C\)

\(G(t) = 2\cdot t^{1/2} + C\) (1)

Where \(C\) is the constant of integration. If we know that \(t = 3\) and \(G(3) = -3\), then the constant of integration:

\(-3 = 2\cdot 3^{1/2} + C\)

\(C = -6.464\)  

The resultant function is \(G(t) = 2\cdot t^{1/2} -6.464\).

Lastly, we evaluate this function at \(t = 17\):

\(G(17) = 2\cdot 17^{1/2}-6.464\)

\(G(17) \approx 1.782\)

42+b+g

Step-by-step explanation:

42+b+g is the only specific answer because b (boys) and g (girls) are not specified as numbers.

The required simplified value of b + g is 21.

Given that,

At a classroom costume party, the average age of the b-boys is g, and the average age of the g girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42- year-old teacher) is b+g,

The average of the values is the ratio of the total sum of values to the number of values.

Here,

The average age of the b-boys is g.
The average age of the g-girls is b.
The average age of everyone at the party (all these boys and girls, plus their 42-year-old teacher) is b+g,

Now,
average of  n = 3 (b , g , b+g)
Average =  g + b + 42 / 3
b + g = (b + g + 42 ) / 3
3b + 3g = b + g +  42
3b - b + 3g - g = 42
2b + 2g = 42
2 (b + g) = 42
b + g = 21

Thus, the required simplified value of b + g is 21.
