Answer:

11.5

Step-by-step explanation:

Divide: 159:6-15

Calculate: 26.5-15

\\11.5//

Answer:

24.8333 with 3 repeating.

Step-by-step explanation:

Lets make an equation for this.

159 - x = 15

X is what we are loooking for so lets isolate it.

Subtract 159 on both sides.

-x = -149

Since both are negative we need to simply cross it out.

x = 149

Now he bought six books, so divide 149 by 6.

You would get 24.8333 with the 3 repeating.

Answer:

([tex]x[/tex], [tex]y[/tex]) = (30, 16)

Step-by-step explanation:

First find the similarity

Since you know the legnth of the hypotenuse (the longest one) for both traingles, you can find the similarity by dividing the longer by the shorter:

50 ÷ 20 = 2.5

The similarity between the 2 triangles is 2.5.

Now find the length of [tex]x[/tex] on the longer one, use the shorter one's length and the similarity:

12 × 2.5 = 30

So the length of [tex]x[/tex] is equal to 30

Now lets find [tex]y[/tex], lets use the length of the larger triangle this time and divide the length of the longer leg (there are 2 legs in every triangle, if you don't know the hypotenus's length, use the pythagorean theorem) and divide it by the similarity:

40 ÷ 2.5 = 16

[tex]y[/tex] = 16

WooHoo! ([tex]x[/tex], [tex]y[/tex]) = (30, 16)

Answer:

c

Step-by-step explanation:

because like it would happen in real life yk and the others dong make sense at all

tell me if its right

Answer:

c)scene

according to me

Slope = - 3

y-int = - 1

Understanding slope intercept

y = mx + b

y = Slope(x) + y-intercept

y = -3x - 1

y = (-3)x + (-1)

Slope = - 3

y-int = - 1

Hope this helps,

Answer:

0.9962

Step-by-step explanation:

The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}\\ \\\mu=mean,\sigma=standard\ deviation, x=raw\ score[/tex]

μ = 20.66°C, σ = 2°C

For x < Singapore temperature, i.e. x < 26

[tex]z=\frac{x-\mu}{\sigma} =\frac{26-20.66}{2}=2.67[/tex]

From the normal distribution table P(x < 26) = P(z < 2.67) = 0.9962

Answer:

See belolw

Step-by-step explanation:

[tex]P=53\text{ft}[/tex]

[tex]P = a+b+c[/tex]

[tex]53=2x-15+x+1+3x-29[/tex]

[tex]53=6x-43[/tex]

[tex]96=6x[/tex]

[tex]x=16[/tex]

[tex]a=2x-15[/tex]

[tex]a=2(16)-15[/tex]

[tex]\boxed{a=17}[/tex]

[tex]b=x+1[/tex]

[tex]b=16+1[/tex]

[tex]\boxed{b=17}[/tex]

[tex]c=3x-29[/tex]

[tex]c=3(16)-29[/tex]

[tex]\boxed{c=19}[/tex]

Answer:

1. x=16, a=17, b=17, c=19

2. k=-2

Step-by-step explanation:

1.

We can set up an equation where all the labeled sides add up to 53, and then find x:

(2x-15)+(x+1)+(3x-29)=53

6x-43=53

6x=96

x=16

Now that we know x, we can plug it back in to the expressions of the triangles to find their side lengths:

a=2(16)-15=17

b=16+1=17

c=3(16)-29=19

2.

Reminder: the slope of a line is its change in y over its change in x. We can then set up an equation:

[tex]\frac{2-k}{k-(-3)}=4\\\frac{2-k}{k+3}=4\\2-k=4k+12\\5k=-10\\k=-2[/tex]

Find roots (zeroes) of :       F(x) = 5x3+x2-32

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  5  and the Trailing Constant is  -32.

The factor(s) are:

of the Leading Coefficient :  1,5

of the Trailing Constant :  1 ,2 ,4 ,8 ,16 ,32

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        -36.00      

     -1       5        -0.20        -32.00      

     -2       1        -2.00        -68.00      

     -2       5        -0.40        -32.16      

     -4       1        -4.00        -336.00

Answer:

B.) X less than or equal to 16.5

Step-by-step explanation:

If you take his limit, 40 and subtract the 7 dollars you will get 33. Then, divide that by two because he will need two tickets and you will get 16.5. It can't be greater than 16.5 because he will go over his budget.

Answer:

x ≤ 16.5

Step-by-step explanation:

40 ≤ 2t + 7 Subtract 7 from both sides.

40 - 7 ≤ 2t + 7 - 7

33 ≤ 2t Divide both sides by 2.

[tex]\frac{33}{2}[/tex] ≤ [tex]\frac{2t}{2}[/tex]

16.5 ≤ t or t ≥ 16.5

First, we convert to a fraction. Then, we simplify.

Answer:

if my math is correct it is $4.39

Step-by-step explanation: do not fully trust this

[tex]y + 7 = - \frac{2}{3}(x + 6) \\ [/tex]

[tex]y + 7 = - \frac{2}{3}x - 4 \\ [/tex]

Subtract sides -7

[tex]y = - \frac{2}{3}x - 4 - 7 \\ [/tex]

Thus ;

[tex]y = f(x)= - \frac{2}{3}x - 11 \\ [/tex]

So the correct answer is (( A )) .

Answer:

The correct answer:

The data are continuous because the data can take on any value in an interval. (A)

Step-by-step explanation:

There are two categories of data:

Discrete data: These are data that have specific values that they can take on. There are limits to what values can be assigned to such categories. for example, The number of countries in a continent, there can either be 15 countries, 50 countries 30 countries, etc. There is not a possibility of having 40.56 countries on this kind of list. hence it is a discrete dataset.

Continuous data are data that can take on any value within an interval or on a particular scale of measurement. In this example, the height of the elephant in meters can be 1.5m, 2m, 1.06m, etc. There is no limit to the possibility of the height of an elephant on a meter scale.
