Answer:

There are 98 blue tiles.

Step-by-step explanation:

-this question is solved by proportions, using a rule of three

-For every 18 red tiles used, 7 blue tiles are used, hence, adding 18 and 7 gives you the total tiles, 7 are blue. How many blue tiles are there out of 425?

The rule of three is:

7 blue- 25 total

x blue- 350 total

Applying cross multiplication:

[tex]25x= 7(350)[/tex]

[tex]x=\frac{7(350)}{25}[/tex]

[tex]x= 98[/tex]

Step-by-step explanation:

intercept on Y is when x=0, y = 16 so if no one goes to competition A, they'll have 16 six-member teams

intercept on x is when y=0, x=24 so if no one goes to competition B, they'll have 24 four-member teams

The small upper quartile is 81.

A random sample of 60 fourth graders are selected.

Since, there are 60 values.

The median of a set of data is the middlemost number or center value in the set. The median is also the number that is halfway into the set.

Sample median will be Average of [tex](\frac{60}{2} )^{th}[/tex] value and [tex](\frac{60}{2}+1)^{th}[/tex] value

The formula to calculate the median of the finite number of data set is given here. The median formula is different for even and odd numbers of observations. Therefore, it is necessary to identify first if we have odd number of values or even number of values in a given data set.

If the total number of observations given is odd, then the formula to calculate the median is:

If the total number of observation is even, then the median formula is:

Sample median = Average of 30th value and 31st value

From the stem and leaf plot :

30th value = 81

31st value = 81

Sample median = (81+81)/2 = 81

Therefore, the sample upper quartile is 81.

Answer: $22

Step-by-step explanation:

The mean of data set A is greater than the mean of data set B i.e. D.

What is mean?

The arithmetic mean, also known as the arithmetic average or simply the mean or average, is the sum of a set of numbers divided by the total number of numbers in the set. The collection frequently consists of a series of findings from a survey, experiment, or observational study.

z-score is a statistical measurement that describes a value's relationship to the mean of a group of values and the formula for the z-score is

z = (x - μ)/σ

x = data point

μ = mean

σ = standard deviation

Now,

Given Data sets

Data Set A: 1, 2, 3, 4, 5, 6, 7

Data Set B: 1, 1, 2, 2, 3, 3, 4

For Data Set A

Mean=(1+2+3+4+5+6+7)/7=28/7=4

For Data Set B

Mean=(1+1+2+2+3+3+4)/7=16/7=2.28

Hence,

          The mean of data set A is greater than the mean of data set B.

The correct option in the given situation is (C) there are twice as many terms in sequence y as there are in sequence x.

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important.

Similar to a set, it has members (also called elements, or terms).

The length of the series is the number of elements (potentially infinite).

In contrast to a set, the same items might appear more than once in a sequence at various points, and unlike a set, the order is important.

A sequence can be described formally as a function from natural numbers (the positions of the sequence's elements) to the items at each of those positions.

An indexed family, which is a function from any index set, can be thought of as a generalization of the idea of a sequence.

So, we have:

x: begin at 2, add 3 = 5

y: begin at 4, add 6 = 10

According to the given statements, the best statement going with the situation is (C) the terms in sequence y are two times the terms in sequence x.

Therefore, the correct option in the given situation is (C) there are twice as many terms in sequence y as there are in sequence x.

On solving the provided question we can say that equation of new line is y + 2 = -1/3(4x + 2)

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

The standardized score of each outcome is 3.85.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by;

z = (x - μ)/σ

Where x is raw score, μ is mean and σ is standard deviation.

Given that;

μ = 23, σ = 3.9, hence for a score x = 38:

Now, substituting the values;

z = (38 - 23) / 3.9 = 3.85

z= 15/3.9

z=3.85

Therefore, the answer will be z score of 3.85;

Answer:

To calculate the total amount Tyler will have paid to the bank, you can use the formula for simple interest:

I = Prt

Where:

I = Interest (the amount Tyler will pay to the bank)

P = Principal (the original amount borrowed)

r = Interest rate (expressed as a decimal)

t = Time (in years)

Plugging in the given values, we have:

I = 42,000 * 0.05 * 15

I = 42,000 * 0.75

I = 31,500

So, Tyler will have paid a total of $31,500 in interest to the bank once he paid the loan back in full after 15 years.

Ken's age can be calculated as follows: x x x = maximum target heart range − - − resting heart rate x = 139 − 73 = 66 x = 139 - 73 = 66 x=139−73=66.

Based on your age, you may calculate your maximum heart rate. Subtract your age from 220 to get a ballpark idea of your maximal age-related heart rate.

For instance, the predicted maximum age-related heart rate for a 50-year-old person would be computed as 220 - 50 years = 170 beats per minute (bpm).

15 seconds are needed to take your pulse. For beats per minute calculation, multiply this number by 4.

The highest rate is determined by deducting your age from 220. Therefore, the maximum heart rate for a 50-year-old is 220 minus 50, or 170 beats per minute.

Therefore, at a 50% level of effort, your goal would be 50% of that maximum, or 85 beats per minute.

The function is f(x)= e^x + 1/3x

To find the value of f(5), put the value of x = 5 in the function f(x)= e^x + 1/3x. Which is equal to f(5) = e^5 + 5/3.

Similarly, to find the value of f(11), put the value of x = 11 in the function f(x)= e^x + 1/3x.

Which is equal to f(11) = e^11 + 11/3

The set of values of k for which the curve y = (k + 1) x² - 3x + (k + 1) lies below the X axis is k > 1/2 and k < -5/2.  

Quadratic functions are polynomial functions of second degree.

The general form of a quadratic function is f(x) = ax² + b x + c.

Given function is y = (k + 1) x² - 3x + (k + 1).

If the curve lies below the X axis, then the curve will not touch the X axis.

This means that, there will be no zeroes for the quadratic function.

So the discriminant will be negative.

Discriminant = [tex]\sqrt{b^{2}-4ac }[/tex] , for f(x) = ax² + b x + c.

So, for the function given,

Discriminant = [tex](-3)^{2} -[4*(k+1)*(k+1)][/tex]

                     = [tex]9-4(k+1)^{2}[/tex]

                     = 9 - 4(k² + 2k + 1)

                     = 9 - 4k² - 8k - 4

                     = -4k² - 8k + 5

-4k² - 8k + 5 < 0

4k² + 8k -5 > 0

Find the zeroes of 4k² + 8k - 5.

Zeroes are, k = [ -8 ± [tex]\sqrt{8^2-(4*4*-5)}[/tex] ] / (2 × 4)

                      = [ -8 ± [tex]\sqrt{144}[/tex] ] / 8

                      = [-8 ± 12] / 8

Zeroes are k = 4/8 = 1/2 and k = -20/8 = -5/2

4k² + 8k -5 = 0 when k = 1/2 and k = -5/2

4k² + 8k -5 > 0, when k > 1/2 and k < -5/2

Hence the values of k are k > 1/2 and k < -5/2 for which the function lies below the X axis.

A progressive tax system includes tax brackets, which indicates that when an individual's income increases, the amount of the tax rates increases gradually. Tax rates for low-income taxpayers are generally low, whereas those for high-income taxpayers are often higher.
