Answer:

Step-by-step explanation:

16/56 + 49/56 = 65/56= 1 9/56

Hey there!

The Distributive Property states the following:

a(b+c)=ab+ac

Where

a, b, and c can be either variables or constants

Now that we know what the property states, let's simplify our expression:

4(5+x)

4 times 5 and 4 times x:

20+4x

Hence, the answer is

[tex]\boxed{\boxed{\bold{20+4x}}}[/tex]

Hope everything is clear,

Let me know if you have any other questions.

Answer:

She scored in the 90th percentile.

90th percentile is better than 90% of the students who took the test, so yes, she will be admitted.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The scores on this test are known to be normally distributed with a mean of 725 and a standard deviation of 115.

This means that [tex]\mu = 725, \sigma = 115[/tex]

She must score better than at least 75% of the students who took the test.

So her z-score should have a pvalue of at least 0.75.

Harriet takes the test and scores 874.5. 1. (2pts) What percentile did Harriet score in?

We have to find the pvalue of Z when X = 874.5.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{874.5 - 725}{115}[/tex]

[tex]Z = 1.3[/tex]

[tex]Z = 1.3[/tex] has a pvalue of 0.9032

She scored in the 90th percentile.

Will Harriet be admitted?

90th percentile is better than 90% of the students who took the test, so yes, she will be admitted.

Answer: a, b, and c

Step-by-step explanation:

Hence, the price of the routes is € 244. Graph A, Graph B, and Graph C are the graphs with negative coefficients.

At different x-intercepts, graphs exhibit varying behaviours. On occasion, the graph will intercept the x-axis and cross it. On occasion, the graph will contact the x-axis and then deviate from it.

Determine the polynomial functions' zeros' even and odd multiplicities.

Plot the graph of a polynomial function using end behaviour, turning points, intercepts, and the Intermediate Value Theorem.

For zeros with even multiplicities, the graphs intersect or are tangent to the x-axis at these x-values. These x-values for zeros with odd multiplicities are where the graphs overlap or meet the x-axis.

Given the data,

Let A, B, C, and D represent the graph.

Currently, the graphs' measurements are

A cubic function that is pointing in the direction of a negative value is used to illustrate the first graph.

Hence, it has a negative coefficient.

The second graph is a parabola as well. It opens downward, which indicates that the leading coefficient is adverse.

The third graph is a linear one that is now tilted downward.

Thus, it has a low efficiency.

Hence , the graphs are solved

Answer:

Tommie planted the most.

Tommie plants twice that amount, and Tommie plants more rows of pepper plants.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Alethea plants 3 rows of carrots for every 1 row of pepper plants.

And, Alethea plants 9 rows of carrots and Tommie plants twice that amount.

Here, Alethea plants 9 rows of carrots and Tommie plants twice that amount.

So, We get;

Tommie plants twice that amount, and Tommie plants more rows of pepper plants.

Answer:

Probability = 0.12025

Step-by-step explanation:

P (Am) = 1/50 = 0.02       {Magazine ad}

P (At) = 1/8 = 0.125         {Television ad}

P (Am ∩ At ) = 1/100 = 0.01      {Both ads}

P (Am U At) = P (Am) + P (At) - P (Am ∩ At )

= 0.02 + 0.125 - 0.01

P (Am U At)  = 0.135       {Person sees either ad}

P (Am' ∩ At') = 1 - P (Am U At)

P (Am' ∩ At')  = 1 - 0.135 = 0.865      {Person sees none ad}

Prob (Purchase) = Prob (Purchase with ad) + Prob (purchase without ad)

P (P/ A) = 1/4 = 0.25 , P (P / A') = 1/10 = 0.1

P (P) = (0.25) (0.135) + (0.1) (0.865)

= 0.03375 + 0.0865

0.12025

[tex]\lim_{x \to 2} \frac{x^{2} }{x^{2} +4} = \frac{1}{2} = f(C)[/tex]

The  function f(x) is continuous

Step-by-step explanation:

Explanation:-

Given that the function

                   [tex]f(x) = \frac{x^{2} }{x^{2} +4}[/tex]

    put  x = c =2

                 [tex]f(c) = f(2) = \frac{(2)^{2} }{(2)^{2} +4} = \frac{4}{8} = \frac{1}{2}[/tex]

              [tex]\lim_{x \to 2} \frac{x^{2} }{x^{2} +4} = \frac{2^{2} }{2^{2} +4} = \frac{4}{4+4} = \frac{4}{8}[/tex]

Answer:

80

Step-by-step explanation:

12 is 15% of 80.

80 movies does the streaming service offer.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

A movie-streaming service offers 12 children's movies.

This is 15% of the total number of movies offered.

let the total number of movies offered be x.

So, 15% of x= 12

15/100 x = 12

x= 1200/15

x= 80

Thus, there were total 80 movies.

d. False

e. Both

Step-by-step explanation:

a.  Explanation: each triangle is composed of three interior angles and three sides which can be of the same length or different lengths

b.  Explanation: isosceles triangles always have two equivalent interior angles, and all three interior angles of any triangle always have a sum of degrees

c. Explanation: The sum of the measures of the angles is always 180 degrees so that means it is not possible.

d. Explanation: exterior angles of a triangle is greater than either of the measures of the remote interior angles so This is a fundamental result in absolute false because its Interior does not depend upon the Angles

e. Explanation: Eh, There's really no explanation for this So, It's both.
