Answer:

6.23*10^6

Step-by-step explanation:

in standard form, it should be written as x*10^n, and x is only allowed from 1-9, so

1) write the first number and add a decimal point(.) and copy down the numbers behind the first number (DO NOT WRITE 0):

6.23

2) check how many numbers are they behind the first number

6230000

~~~~~~

in here, it's 6numbers, so 10^6

3) all in all, your answer is

6.23*10^6

Answer:

-1.25

Step-by-step explanation:

2x - 7 = 3

x = -2y - 2

3 + 7 = 2x

x = 5

5 = -2y - 2

5 = -4y

5 = -4 times y

-

The equation of the parallel line is: y = 1/2x + 5.

The slope (m) of parallel lines are the same.

Given the equation, y = 1/2x - 7, the slope (m) is 1/2. Therefore, the slope of the line that passes through (-4, 3) would be m = 1/2.

To find the y-intercept (b), substitute m = 1/2 and (x, y) = (-4, 3) into y = mx + b.

3 = 1/2(-4) + b

3 = -2 + b

3 + 2 = b

5 = b

b = 5

Substitute m = 1/2 and b = 5 into y = mx + b:

y = 1/2x + 5

The equation is: y = 1/2x + 5.

Answer:

x = 7 degrees

Step-by-step explanation:

The unlabelled angle at M   PLUS   12x + 24 = 180

  then   the unlabelled interior angle is  180 - (12x+24)

The sum of the interior angles then = 180

 80 + 4x  +     180-(12x+24) = 180

Answer: Answer:

The perimeter of the polygon are

PQ = 5

RS = 5

PR = √74 = 8.60

QS = √74 = 8.60

QR = 7

Step-by-step explanation:

To calculate the perimeter of a polygon, polygon is like a coordinate with points, to find the length, we use this formula

d = √(x _2 - x_1)^2 + (y_2 - y_1)^2

Let's start from the first two vertices P ( 0 , 4) and Q(5 , 4)

x_1 = 0

y_1 = 4

x_2 = 5

y_2 = 4

PQ = √ ( 5 - 0)^2 + ( 4 - 4)^2

= √ 5^2 + 0^2

= √ 25

= 5

Between R( 5 , -3) and S ( 0 , -3)

x_1 = 5

y_1 = -3

x_2 = 0

y_2 = -3

RS = √ ( 0 - 5)^2 + ( -3 - (-3))^2

= √( -5)^2 + ( -3 + 3)^2

= √ 25 + 0

= √ 25

= 5

Between P( 0 , 4) and R (5 , -3)

x_1 = 0

y_1 = 4

x_2 = 5

y_2 = -3

PR = √( 5 - 0)^2 + ( -3 - 4)^2

= √ 5^2 + (-7)^2

= √ 25 + 49

= √ 74

= 8.60

Between Q ( 5 , 4) and S(0 ,-3)

x_1 = 5

y_1 = 4

x_2 = 0

y_2 = -3

QS = √ ( 0 - 5)^2 + ( -3 - 4)^2

= √ -5^2 + -7^2

= √ 25 + 49

= √ 74

= 8.60

Between Q( 5,4) and R(5 , -3)

x_1 = 5

y_1 = 4

x_2 = 5

y_2 = -3

QR = √ (5 - 5)^2 + ( -3 - 4)^2

= √ 0^2 + (-7)^2

= √ 0 + 49

= √ 49

She must win the next 8 consecutive games to get 80% and after that loose the next 12 games to get to 50%.

She has won 8 out of 12 days. Thus, percentage of winning is;

P(winning) = 8/12 * 100%

P(Winning) = 75%

To arrive at 80% winning, it means that the number of extra consecutive games she must win is;

(8 + x)/(12 + x) = 80/100

10(8 + x) = 8(12 + x)

80 + 10x = 96 + 8x

2x = 16

x = 8

Thus, she must win the next 8 consecutive games to get 80%.

For her to get to 50% after that, it means that;

(16 - x)/(20 - x) = 50/100

(16 - x)/(20 - x) = 1/2

2(16 - x) = 20 - x

32 - 2x = 20 - x

Using the t-distribution, it is found that the 95% confidence interval for the population mean rating for Miami is (5.73, 6.95).

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 50 - 1 = 49 df, is t = 2.0096.

Considering the given sample, the other parameters are given as follows:

[tex]\overline{x} = 6.34, s = 2.16, n = 50[/tex]

Hence, the bounds of the interval are:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 6.34 - 2.0096\frac{2.16}{\sqrt{50}} = 5.73[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 6.34 + 2.0096\frac{2.16}{\sqrt{50}} = 6.95[/tex]

The Area of the region bounded by curves = 9 sq.units.

Area is the space occupied by a two dimensional figure on a two dimensional space coordinate.

The two curves given are

x² + 4y - 8 = 0 and x =2y​

Convert the two equation so ‘x’ is the dependent variable.

y = -(1/4) x² +2 and y = (1/2)x

Find the limit by the intersection point of both the graph

so (-4, 2) and (2, 1)

The x-values of the line are greater so subtract the parabola:

A = ∫ (1/2)x - (-(1/4) x² +2 ) in the limits of (-4 and 1)

The Area = 9 sq.units.
