Answer number 7 please thank you

The probability that heads would be obtained 15 or fewer times when this coin is flipped 25 times is 0.370

The given parameters are:

The probability is represented using the following binomial formula

[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]

Using the above formula, we have:

[tex]P(x \le 15) = 0.370[/tex]

Hence, the probability is 0.370

Answer:

m<A=40˚, m<C = 90˚

Step-by-step explanation:

a line is 180˚, and half of a line (C) would be 90˚.  B + A has to equal 90˚, so A has to be 40˚

Answer:

For question 1)

Line A's Gradient= -1

y=-x+5 where 5 is the y-intercept

Line B's Gradient= 1

y=x+3 where 3 is the y-intercept

By equating two equations....

The expression can be subtracted from the area of the rectangle to give the area of the parallelogram RSTU (18+4).

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

The coordinates of parallelogram RSTU are

R(-4, -3), S(-5, 1), T(4, 3), U(5, -1)

The lengths of the sides are

RS = 4.1231

RT = 10

ST = 9.2195

SU = 10.198

TU = 4.1231

UR = 9.2195

Therefore, by definition of a parallelogram, we have;

RS║TU and ST║UR

The slope of RS = (1 - (-3))/(-5 - (-4)) = -4

The slope of ST = (3 - 1)/(4 - (-5)) = 2/9

The equation of the line perpendicular to ST is

y - 1 = -9/2×(x - (-5))

y = -9x/2 - 43/2

The equation of RS = y - (-3) = 1/4×(x - (-4)) = x/4 + 1

y = x/4 - 2

The point where the two lines meet

-9x/2 - 43/2  =  x/4 - 2

x = -78/19

y = -115/38

The length of the side of the rectangle = 4.1245

The excess width of the rectangle = 0.1085

The expression can be subtracted from the area of the rectangle to give the area of the parallelogram RSTU (18+4).

Answer:

13: 16

14: 6.28

15: √45

Step-by-step explanation:

13: Count the number of spaces from A to D or B to C, which is 4.

Then, count the number of spaces from A to B or C to D, which is also 4.

After that, multiply the two numbers. You should now have an answer of 16.

14: You want to find the diameter of the circle, which is 2.

Then, multiply 2 by 3.14, aka pi. You should now have an answer of 6.28.

*15: Count the number of spaces from A to C, which is 6.

Then, count the number of spaces from A to B, which is 3.

After that, square both of the numbers. 6 x 6 = 36 and 3 x 3 = 9.

Now, the final step. Add both numbers together. 36 + 9 = 45.

You should now have an answer of √45.

Answer:

because It's rounded to the nearest hundred place

Step-by-step explanation:

Given equation:

recall that,

[tex] \ln(a ) = b \iff {e}^{b} = a[/tex]

remember, In is natural logarithm which is actually nothing but common logarithm with the base euler's number (e) . anyway rewriting lnx=-3 yields:

[tex] \ln( x ) = - 3\\ \iff {e}^{ - 3} = \frac{1}{ {e}^{3} } [/tex]

1/e³ is approximately 0.0497870684..... , rounding it to the nearest hundred place would be 0.05 which is the same answer as your textbook .

Answer: D) 375

Step-by-step explanation:

    We will find 30% of 1,250 since 30% did not vote. A percent divided by 100 becomes a decimal.

Because m and n are whole numbers, we only have 3 values for m, and 3 values for n :

[tex]1^{121} ; 11^{11} ;121^{1}[/tex] (or you can say because 121 only have the factors of 1 ; 11 ; 121, those are the only possible values for m and n, then conclude the possible values)

Now, we will substitute them in :

If m = 1 ; n = 121

[tex](1-1)^{121+1}[/tex] = 0

If m = 11 ; n = 11

[tex](11-1)^{11+1}[/tex] = 1000000000000

y = 1

A simple formula to solve inverse relations is y+x=k, where k is a constant

Now using 5 as the constant and x = 4, y can be solved by doing 4 + y = 5

y = 1

Using translation concepts, it is found that function g(x) is given by:

[tex]g(x) = \frac{1}{5}\log_{2}{x} - 4[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent function is given by:

[tex]f(x) = \log_{2}{x}[/tex]

It was shifted 4 units down, hence:

[tex]g(x) = \log_{2}{x} - 4[/tex]

It was vertically compressed by a factor of 0.2, hence:
