Using the Central Limit Theorem, it is found that the distribution of the sample means of the weights of the 7 adult standard poodles is normal, with mean of 50 pounds and standard deviation of 5.67 pounds.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem, for the population, [tex]\mu = 50, \sigma = 15[/tex].

Answer: the answer - 2/15

Step-by-step explanation: i took the test

The value of the expression [2- |-2/3 -2(-1/5)|] ÷ (-13) is -2/15

Numbers, symbols and operators grouped together that show the value of something.

Given that an expression [2- |-2/3 -2(-1/5)|] ÷ (-13)

[2- |-2/3 -2(-1/5)|] ÷ (-13)

= [2 - 4/15]/ (-13)

= 26/15*1/(-13)

Answer:

0

Step-by-step explanation:

1. First, we should know the slope-intercept form of any equation: y = mx + b.

2. In the equation y = -2/3(x), it appears that the variables we can see are y, m, and x. However, the y-intercept, b, is still there with the value of 0.

Therefore, the y-intercept is 0.

(3)1. Find the coordinates of all points where the lines

x + y = 8, y = 5, and x = 1 intersect.

Step-by-step explanation:

this answer

The coordinates of all points where the lines x + y = 8, y = 5, and x = 1 intersect are (0, 5), (1, 0), (3, 5) and (1, 7).

Given that;

The equation of lines is,

x + y = 8

y = 5

x = 1

Now all the coordinates of all points where the lines x + y = 8, y = 5, and x = 1 intersect are find as,

x + y = 8

Put y = 5;

x + 5 = 8

x = 8 - 5

x = 3

Put x = 1;

1 + y = 8

y = 8 - 1

y = 7

Therefore, the points are (0, 5), (1, 0), (3, 5) and (1, 7).

Answer:

I don't understand clear ur question

Step-by-step explanation:

the rules of logarithm.

log(a×b) = log(a) + log(b)

log(a^b) = b×log(a)

2×log(x) = log(16) + log(4)

now, using the above knowledge :

log(x²) = log(16×4)

=>

x² = 16×4 = 64

x = ±8

and since a logarithm of a negative number is undefined the only plausible solution is

x = 8

Answer:

(x+1.5)^2 -10.25

Step-by-step explanation:

1)first, we half 3 to give us 1.5

(x+1.5)^2

2)square 1.5=2.25

so far we have (x+1.5)^2 - 2.25 --- the negative sign from 2.25 is part of the formula

3)we subtract 8 from -2.25. the 8 comes from here shown in bold ----- x^2+3x-8

4) (x+1.5)^2 -2.25 - 8

5)simplify the last part by doing -2.25 - 8= -10.25

6)answer is (x+1.5)^2 - 10.25

the answer is 4160$

     After 6 years of investment of $3200 compounded continuously, final amount in the account will be $4319.55.

Moneysaver's Bank offers a saving account with the features as,

Expression to calculate the final amount when compounded continuously,

Final amount = [tex]P.e^{rt}[/tex]

Here, P = Principal amount

r = Rate of interest

t = Duration of investment

By substituting the values in the expression,

Answer:

  -3, 13

Step-by-step explanation:

8 units to the left of 5 on the number line is 5-8 = -3.

8 units to the right of 5 on the number line is 5+8 = 13.

The possible locations of Y are -3 or 13.

x = -3 ==> 2(-3) + 1 = (-6) + 1 = -5

x = 9 ==> 2(9) + 1 = 18 + 1 = 19

x = 15 ==> 2(15) + 1 = 30 + 1 = 31

Step-by-step explanation:

Triangle KLN has 3 equal angles so all sides of it must be equal ( equilateral triangle)

y+3=10

y=7

Triangle LNM has 2 equal angles as in an isosceles triangle so LN= ML

So sides opposite to equal angles must be equal too

Answer:

C = 50°

Step-by-step explanation:

In the given figure, it tells us which angles are the same. ( You can look at the red marks. )

So, 68 + 62 = 130.

As we all know, the sum of all angles in any triangle is 180.

So, 180 - 130 = 50.

That is Angle C.

Answer:

12cm by 15cm

8cm by 10cm

4cm by 5cm

Step-by-step explanation:

it is made smaller so any values smaller than 15cm but in ratio of 4:5 can be answer

Answer:

15 cm is the new dimensions of new photograph

Step-by-step explanation:

initial dimension of shorter side = 8 cm

initial dimension of longer side = 10 cm

final dimension ofshorter side = 12 cm

finial dimension of longer side = x cm

The enlargement always ensure the aspect ratio

aspect ratio = lonter side/shorter side

equating, [tex]\frac{10}{8}[/tex] = [tex]\frac{x}{12}[/tex]

Solving for x,

10 × 12 = 8 × x

[tex]x = \frac{10 x 12 }{8} = \frac{120}{8 } = 15[/tex]

        /\

        that says 10 x 12

longer side is 15cm

Answer:

a. = 36km

b. Perimeter = 108km

c. Area = 486km^2

Step-by-step explanation:

Pythagoras theorem

a^2 + b^2 = c^2

27^2 + b^2 = 45^2

b^2 = 45^2 - 27^2

b^2 = 1296

b = [tex]\sqrt{1296}[/tex]

b = 36km

Perimeter

a + b + c

27 + 36 + 45 = 108

Perimeter = 108km

Area = [tex]\frac{ab}{2}[/tex]

Area = [tex]\frac{27 * 36}{2}[/tex]

Area = [tex]\frac{972}{2}[/tex]

Area = 486km^2

Step-by-step explanation:

Let's pick two points on the line: [tex]P_1(-4, 1)[/tex] and [tex]P_2(2, -2).[/tex] Let's calculate the slope of this line using these points:

[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-2 - 1}{2 - (-4)} = -\dfrac{1}{2}[/tex]

With this value of the slope, we can write the general slope-intercept form of the equation as

[tex]y = -\frac{1}{2}x + b[/tex]

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

[tex]-2 = -\frac{1}{2}(2) + b \Rightarrow b = -1[/tex]

Therefore, the slope-intercept form of the equation is

[tex]y = -\frac{1}{2}x - 1[/tex]

Answer:

B. y = 58

Step-by-step explanation:

b) y=58 you follow the instructions

...............................................................................................................................................

The given quadratic function is      

y= 2x^2 - 2x - 2

We have to find the value of the function y at x=6.

Substitute x=6 in the given function.      

y= 2(6)^2 - 2(6) - 2

y= 2(36) - 12 - 2

y= 72 - 14

y= 58

The value of the function is 58 at x=6 is 58.

Therefore the correct option is B.

For a matrix to be singular, the determinant of the matrix must be zero.

For the given 2 by 2 matrix, for the matrix to be a singular matrix then, its determinant must be zero as shown;

(5* 6) - (3 * x) = 0

30 - 3x = 0

3x = 30
