Answer:

x = 19

y = 16

Step-by-step explanation:

10x - 9y = 46

-2x + 3y = 10

Time the second equation by 5

10x - 9y = 46

-10x + 15y = 50

6y = 96

y = 16

Now put in 16 for y and solve for x

10x - 9(16) = 46

10x - 144 = 46

10x = 190

x = 19

Step-by-step explanation:

If the terminal side of θ is in quadrant || and sin θ = 5/13, then the value of cos θ = -12/13.

Given that,

Terminal side of θ is in quadrant ||.

Sin θ = 5/13

We have the trigonometric identity,

sin² θ + cos² θ = 1

Substituting the value of Sin θ = 5/13, we get,

(5/13)² + cos² θ = 1

cos² θ = 1 - (5/13)²

          = 1 - 25/169

          = 144/169

cos θ = √ (144/169)

         = ± 12/13

We have the terminal side of θ is in second quadrant. In the second quadrant, all the trigonometric values except sin are negative.

So, cos θ = -12/13

The judge's certainty of the suspect's guilt should be around 37.9% based on the given probabilities and Bayes' theorem.

Based on the given information, we can calculate the probability of the suspect's guilt using Bayes' theorem.

Initially, the judge believed there was a 65% chance of the suspect's guilt. Let's represent this as P(G).

The new information is that there is an 85% chance that the criminal is left-handed. Let's denote this as P(L|G), where L represents left-handedness and G represents guilt.

We also know that 23% of the population is left-handed, which can be represented as P(L).

Now, we can use Bayes' theorem to calculate the new probability of guilt (P(G|L)) given the left-handedness information:

P(G|L) = (P(L|G) * P(G)) / P(L)

Plugging in the values, we have:

P(G|L) = (0.85 * 0.65) / 0.23

Calculating this, we find that P(G|L) is approximately 0.379 or 37.9%.

Therefore, with this new information, the judge should be approximately 37.9% certain of the guilt of the suspect.

Based on the study described, it is true that physical activities lead to lower stress and a sample size of 1508 is large enough to establish causal relationships (Option A).

In this study, the researchers analyzed the effect of physical activity on stress levels. To do this, they chose a representative sample, which included 1508 teenagers and compared the results not only by physical activity but also by gender.

Based on this, the sample is representative and due to the differences in the data the results showed that the more teenagers exercise the less stressed they are.

While linear regression can be a useful tool for prediction, it is important to consider the quality of the data, assess the linearity assumption, and be cautious when extrapolating beyond the observed data range.

This is an example of using linear regression to predict the weight of a kitten at a specific time (10 weeks in this case) based on the given linear model ŷ = 1.7 + 1.48t.

Using linear regression to make predictions is a common practice and can provide reasonable estimates in many cases. However, whether it is considered a best practice for prediction depends on various factors. Here are a few considerations:

Data quality: The accuracy and reliability of the predictions heavily depend on the quality of the data used to build the linear model. If the data used for training the model is representative and accurately reflects the underlying relationship, the predictions are likely to be more reliable.

Linearity assumption: Linear regression assumes a linear relationship between the predictor variable (in this case, time) and the response variable (kitten weight). If the relationship is not truly linear, the predictions may be less accurate. It is important to assess the linearity assumption and consider alternative models if needed.

Extrapolation: When making predictions outside the range of the observed data (such as predicting the weight at 10 weeks when the data only goes up to 8 weeks), caution should be exercised. Extrapolating beyond the observed range can introduce more uncertainty and may lead to less accurate predictions.

In summary, while linear regression can be a useful tool for prediction, it is important to consider the quality of the data, assess the linearity assumption, and be cautious when extrapolating beyond the observed data range.

The probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring, this statement is false.

The union of two or more sets refers to the set with all the elements belonging to each set. An element is said to be in the union if it lies to at least one of the sets.

The intersection of two or more sets refers to the set of elements universal to each set. An element is in the intersection if it occurs in all of the sets.

The event that both A and B occur is the intersection of the events A occurs and B occurs. As such, it is a subset of each and cannot, therefore, have a larger probability than either one individually.

How to subtract unlike fractions:

Heterogeneous fractions are fractions that have different denominators.

To subtract heterogeneous fractions we follow these steps:

It is possible to use a relational operator and math operators in the same expression.

In programming, you can use relational operators (e.g., <, >, ==, !=) and math operators (e.g., +, -, *, /) together in the same expression. This is often used in conditional statements or loops to compare calculated values.

For example, consider the following expression:

`if (2 * 3) > (4 + 1)`

In this expression, we have math operators (*) and (+) and a relational operator (>). The math operations are evaluated first, resulting in:

`if (6) > (5)`

Then, the relational operator (>) is evaluated, and the expression becomes:

`if True`

The expression is true because 6 is greater than 5.

It is possible to use both relational operators and math operators in the same expression, which can be useful in various programming situations such as conditional statements or loops.

To find loga² b, we can use the logarithmic properties, specifically the power rule of logarithms, which states that loga x² = 2 loga x.

Given that loga = 0.6 and logb = 0.7, we can rewrite loga² b as:

loga² b = 2 loga b

Substituting the given values, we have:

loga² b = 2 * loga b = 2 * 0.7 = 1.4

Step-by-step explanation:

A quadratic equation can be constructed from their roots,

\((x - p)(x - q)\)

where p and q are the roots.

Here the roots are

\(2 - \sqrt{3} \)

and

\(2 + \sqrt{3} \)

So we have

\((x - (2 - \sqrt{3} ))(x - (2 + \sqrt{3} ))\)

\( {x}^{2} - 2x - x \sqrt{3} - 2x + x \sqrt{3} + 4 - 3\)

\( {x}^{2} - 4x + 1 = 0\)
