Well 1/2 of 4/5 would be about 2.5/5. So summing it up. . .

Answer:

100

Step-by-step explanation:

360 is the total degree for every quadrilateral. 80+75+105=260. 360-260=100.

The set of numbers that have 11 as a common factor is {154, 231}.

The number that divides two or more numbers is called a common factor.

Given are the pair of numbers as -

{154, 231}

{143, 221}

{33, 39}

{77, 91}

The pair of numbers with the common factor 11 is {154, 231}.

Therefore, the set of numbers that have 11 as a common factor is {154, 231}.

Option A is correct, a parent function  best describes the quadratic function.

The quadratic function with a vertex at the origin and opening upward is best described as a parent function.

A parent function is the most basic form of a particular type of function.

In the case of quadratic functions, the parent function is f(x) = x².

It has a vertex at the origin (0, 0) and opens upward.

Therefore, a parent function  best describes the quadratic function.

Step-by-step explanation:

    Remember the SAS rule is that you know the measure of 2 sides and their angle in between. (Note that SSA side side angle DOESN'T work.)  For the first question we know that sides JH and LM are congruent, and sides GJ and MK are as well. Secondly, we know that angles M and J are congruent. The question is; does this problem follow the SAS (side angle side) rule? Yes, their are two proven congruent sides on the two triangles, and the angle between them is proven congruent as well.

Second one is congruent because it follows the SSS rule (side side side) ie: all sides are congruent, so therefore the triangles are congruent.

Think about the third one. Is it congruent or not. (To be congruent it has to follow SSS, or SAS) Comment below so I can correct you.

Answer:

49×7=x

x=343 miles

Step-by-step explanation:

49hours×7mph=343miles

Answer:

The answer is below

Step-by-step explanation:

1) The length of the south side of the field = (5x + 2) + (x² - 9) + (x² - 7x +12) = x² + x² + 5x - 7x + 2 - 9 + 12 = 2x² - 2x + 5

2) The perimeter of pumpkin field = 2(length + breadth) = 2[(5x - 2) + (5x + 2)] = 2[5x + 5x - 2 + 2] = 2(10x)

The perimeter of pumpkin field = 20x

3) The perimeter of pumpkin field is useful in case Bob wants to fence the pumpkin field.

4) The perimeter of potato field = 2(length + breadth) = 2[(x + 6) + (x² - 7x + 12)] = 2[x² - 7x + x + 6 + 12] = 2(x² - 6x + 18)

The perimeter of potato field = 2x² - 12x + 36

5) Area of squash field = length * breadth = (4x) * (x)

Area of squash field = 4x²

6) The area of the squash field would be important if Bob want to determine the number of squash seeds that would be enough for the field.

7) Area of pumpkin field = length * breadth = (5x - 2) * (5x + 2) = 25x² + 10x - 10x - 4

Area of pumpkin field = 25x² - 4

Area of pumpkin field and squash field = 4x² + (25x² - 4) = 29x² - 4

Answer:

a) 0.7734

Step-by-step explanation:

Problems of normal distributions can be solved using 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.

In this question, we have that:

[tex]\mu = 101, \sigma = 24[/tex]

(a) what proportion of children aged 13 to 15 years old have scores on this test above 83 ?

This is 1 subtracted by the pvalue of Z when X = 83. So

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

[tex]Z = \frac{83 - 101}{24}[/tex]

[tex]Z = -0.75[/tex]

[tex]Z = -0.75[/tex] has a pvalue of 0.2266

1 - 0.2266 = 0.7734

The answer is 0.7734

Answer:

D. (8, –10)

Step-by-step explanation:

(8, -10) passes through this line.

The correct option is D

By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.

As per the given data:

We are given a line KL in the diagram, and we have to find out which point out of the given options will satisfy the equation of the line which is parallel to KL and passes through M.

Using the intercept form equation of line KL:

x/a + y/b = 1 [a and b are x and y intercepts respectively]

x/6 + y/4 = 1

4x + 6y = 24

Slope of this line = -a/b = -4/6 = -2/3

The line parallel to this will have the same slope and should pass through (-4, -2)

y - (-4) = (-2)/3 [x - (-2)]

y + 4 = (-2/3)[x + 2]

3y + 12 = -2x - 4

2x + 3y + 14 = 0

Clearly (8, -10) passes through this line.

2(8) + 3(-10) + 14 = 0

Hence, (8, -10) passes through this line.

Answer:

Step-by-step explanation:

Answer:

[tex]g(x) = 12 {e}^{ - x - 7} [/tex]

Step-by-step explanation:

The parent function is

[tex]g(x) = e {}^{x} [/tex]

First it is asked to reflect over the y axis so using the rule

[tex]g(x) = g( - x)[/tex]

Our function looks like

[tex]g(x) = e {}^{ - x} [/tex]

Then we are asked to shift the equation to the right 7. When shifting to the right or move the x axis, instead of adding 7 we would want to subtract 7 since the x axis is the independent variable and we must respect the y axis which is the dependent so using the rule

[tex]g(x) = g(x - h)[/tex]

When subtracting a 7 it looks like now

where h is the number we move . Now we are asked to apply a vertical stretch of 12. Since vertical stretch refers to the y axis, we are just going to multiply the function by 12 using the rule

[tex]g(x) = a \times g(x)[/tex]

where a is the vertical stretch. So now it would look like

[tex]g(x) = 12 {e}^{ - x - 7} [/tex]
