Answer:

(x + 1 s 1) n (x + 12 1)

(x +1<1) n (x + 1 > 1)

Step-by-step explanation:

Just simplify each the statements.

Then compare and and see if the statements are contradictory and therefore FALSE, if so, then there is no solution.

(x + 1<-1) n (x + 1< 1)

(x <-2) n (x < 0) which is true, so there is a solution.

(x + 1 s 1) n (x + 12 1)

this doesn't make sense so there is no solution.

(x +1<1) n (x + 1 > 1)

(x < 0) n (x > 0)

This is not possible, the statements are contradictory and therefore FALSE, so there is no solution.

Answer:

Step-by-step explanation:

To find the five-number summary for the commute times (in minutes) of the two samples, we would determine the lowest, highest, first quartile, median and third quartile for each set of values.

1) Considering the data for faculty, arranging in ascending order, it becomes

5 12 12 12 15 22 25 30 35 45

Minimum = 5

Maximum = 45

Median = (15 + 22)/2 = 18.5

Placing the median in the data, it becomes

5 12 12 12 15 18.5 22 25 30 35 45

The median divides the data into the lower and upper halves

First quartile is the 25% mark. It is also the middle of the lower halve. Therefore,

First quartile = 12

Third quartile is the 75% mark. It is also the middle of the upper halve. Therefore,

Third quartile = 30

2) Considering the data for students, arranging in ascending order, it becomes

10 12 14 15 15 20 22 24 25 30

Minimum = 10

Maximum = 30

Median = (15 + 20)/2 = 17.5

Placing the median in the data, it becomes

10 12 14 15 15 17.5 20 22 24 25 30

The median divides the data into the lower and upper halves

First quartile is the 25% mark. It is also the middle of the lower halve. Therefore,

First quartile = 14

Third quartile is the 75% mark. It is also the middle of the upper halve. Therefore,

Third quartile = 24

Answer:

2(b + 3c)²(b + 3c)² is equivalent to

2b^4 + 8b³c + 12b²c² + 8b²c³ + 2c^4

Step-by-step explanation:

The expression

2(b + 3c)²(b + 3c)²

Is equivalent to the expression

2(b + 3c)^4

This can be further expanded using the Pascals triangle as

2(b^4 + 4b³c + 6b²c² + 4b²c³ + c^4)

= 2b^4 + 8b³c + 12b²c² + 8b²c³ + 2c^4

Answer:

[tex]y = 4(x^{2} + 8x + 15) = 4x^{2} + 32x + 60[/tex]

Step-by-step explanation:

A parabola has the following format:

[tex]y = f(x) = ax^{2} + bx + c[/tex]

If a is positive, it's minium value is:

[tex]y_{M} = -\frac{\bigtriangleup}{4a}[/tex]

In which

[tex]\bigtriangleup = b^{2} - 4ac[/tex]

Factoring:

[tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], in which [tex]x_{1} and x_{2}[/tex] are the intercepts.

In this question:

[tex]x_{1} = -5, x_{2} = -3[/tex]

So

[tex]a(x - x_{1})*(x - x_{2}) = a*(x - (-5))*(x - (-3)) = a*(x+5)*(x+3) = a*(x^{2} + 8x + 15)[/tex]

Suppose a = 1, we have:

[tex]x^{2} + 8x + 15[/tex]

[tex]\bigtriangleup = 8^{2} - 4*1*15 = 4[/tex]

The minimum value will be:

[tex]y_{M} = -\frac{4}{4} = -1[/tex]

We want this minimum value to be -4, which is 4 times the current minimum value, so we need to multiply a by 4. Then

[tex]a = 4[/tex]

And the parabola is:

[tex]y = 4(x^{2} + 8x + 15) = 4x^{2} + 32x + 60[/tex]

Cost of necklace is $939 and cost of bracelet is 645

Given that;

Number of necklace = 1

Number of bracelets = 4

Cost of necklace = Cost of bracelets + 294

Find:

Cost of necklace

Computation:

Assume;

Cost of bracelets = a

Cost of necklace = a + 294

So,

4a + a + 294 = 3519

5a + 294 = 3519

5a = 3225

a = 645

Cost of necklace = 645 + 294

Cost of necklace = $939

Answer:

Step-by-step explanation:

Let the number of days be x because x is the independent variable

Any y is the number of calories consumed the dependent variable.

Now slope = y2 - y2/ x2 - x2

= 10600-4100/8-3

= 6500/5 = 1300

From our analysis we know it consumes 1300 per day so ideally on day 3 we expect him to consume 1300x3= 3900

But the given value is 4100

This means it's inherent energy is 4100-3900= 200

This is the y- intercept and it occurs when x= 0

from the above explanation we know that

C = 200. and it's the y- intercept.

Look at the general equation of a line

y = mx + C; when x= 0, y = C; note we define C as the value of y when x = 0

And we got:

[tex] 280 x10^4[/tex]

And if we move the decimal point two units to the left we got:

[tex] 2.8 x10^6[/tex]

Step-by-step explanation:

We know that each elefeant weight about [tex]1.4 x10^4[/tex]

And we have a total of 200 elephants so then we can find the total weights for the elephants with this formula:

[tex] 200 *1.4*10^4[/tex]

Using the properties of multiplication we can do this:

[tex] (200*1.4) *10^4[/tex]

And we got:

[tex] 280 x10^4[/tex]

And if we move the decimal point two units to the left we got:

[tex] 2.8 x10^6[/tex]

Step-by-step explanation:

When the problem says 3f(x), it means that you are multiplying f(x) by 3. The same goes for 2g(x).

[tex]3(2x^2+8x-4)= 6x^2+24x-12[/tex]

[tex]2(5x+6) = 10x+12[/tex]

Now, we subtract f(x) from g(x) after being multiplied.

Answer:

Yes, they differ across the two delivery styles of the previous course.

Step-by-step explanation:

So, we are given the following data or information or parameters from the question above;

Flipped(group) => 166(n) 2.45(l) 1.09(s).

Traditional(group) => 129(n) 1.59(l) 1.20(s).

Therefore, the hypothesis is given below as; Jo : b1 = b2, Jx : b1 ≠ b2.

Recall that we are given; 166 = (n1), 2.45 = (l1), 1.09 = (s1) and 129 = (n2) , 1.59 = (l2), 1.20 = (s2).

Therefore, we will be using the following mathematical representation or formula to solve this question;

s = √(s1^2/ n1 + s2^2/n2).

When we slot it the values accordingly and solve for s, we will have a value of;

s = 0.1354.

Thus , for our t*, we can calculate that by using the formula below:

t*= l1 - l2/ s.= (2.45 - 1.59)/ 0.1354= 6.35.

Thus: p value = 2P(V> 6.35) = 2.1 × 10^-10.

Since we are given that a=0.01, thus, p value is less than 0.01 we can reject Jo.

Answer:

  B.  129.7°

Step-by-step explanation:

The law of sines tells you ...

  sin(C)/c = sin(A)/a

  sin(C) = (c/a)sin(A)

  C = arcsin((c/a)sin(A)) = arcsin(117/57·sin(22°)) = 50.3°

The value shown is the result of using the arcsin function, but we know that the supplement of this angle has the same sine value. Then, we could have ...

  C = 180° -50.3° = 129.7°

The figure shows C as an obtuse angle, so we choose this latter value as the appropriate answer to this question.

  C = 129.7° . . . . . matches choice B

_____

Comment on the answer

We note that choice C (50.3°) matches the result of straightforward use of the law of sines. This triangle actually has two solutions for angle C, as we have noted above. Often, figures are "not to scale," so the appearance of angle C as an obtuse angle cannot always be taken at face value. Here, because both choices for angle C are offered, we use the appearance of the figure to help decide the right one.
