Answer:

0.53347

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score = -0.084 °C

μ is the population mean = 0 °C

σ is the population standard deviation = 1°C

Z score =x - μ/σ

= -0.084 - 0/1

= -0.084

Probability value from Z-Table:

P(x<-0.084) = 0.46653

P(x>-0.084) = 1 - P(x<-0.084) = 0.53347

The probability of obtaining a reading greater than -0.084°C = P(x > -0.084) =

is 0.53347

Answer:

d. -1

Step-by-step explanation:

the slope is the rise over the run from one point to another.

i hope this helps :)

Each line is 1 unit.

Use the dots A and B

A is located at (-3,3)

B is located at (3,-3)

Slope is the change in y over the change in x

Slope = (-3 -3) / (3 - -3)

Slope = -6/6

Slope = -1

The answer is D -1

Answer:

16767

Step-by-step explanation:

Each new term is found by multiplying the previous term by 3.  Thus, 3 is the common ratio.  The formula for this geometric series is therefore

a(n) = 23*3^(n - 1).

The 7th term is a(7) = 23*3^6 = 16767

Answer:

x=3 + y=3 =6

Step-by-step explanation:

first you have to find out what can equal 6 and 3 plus 3 equals 6 so that's  your answer

Answer:

[tex]2\sqrt{3}[/tex] or 2 square roots of 3

Step-by-step explanation:

The figure shown is a 30 - 60 - 90 degree special right triangle

The image below shows the properties of a 30 - 60 - 90 degree special right triangle

We are asked to find the longer leg (v)

The image tells us that the longer leg is equal to the shorter leg to the square root of 3

so v = 2 to the square of 3

Hence, the answer is the first one

Answer:

x = 10 degrees

Step-by-step explanation:

the sum of angles in triangle = 180 degrees

11x - 5 + 6x + 5 + x = 180

combine

18x = 180

divide

x = 10 degrees

Answer:

Very sorry if im wrong.

Step-by-step explanation:

(x - 4) (x + 1) (2 x - 3) = 0

2 x^3 + x + 12 = 9 x^2

2 (x - 3/2)^3 - 25/2 (x - 3/2) = 0

Answer:

The sum of the first 47 terms of the series, 12, 16, 20, ... S₄₈ is 4,888

Step-by-step explanation:

The given series is;

12, 16, 20, ...,

Therefore, the first term of the series is, a = 12

The common difference of series is found as follows;

The difference between subsequent terms, 12 and 16 is  16 - 12 = 4

The difference between subsequent terms, 16, and 20 is  20 - 16 = 4

Therefore, the common difference, d = 4

The series is therefore an arithmetic projection, AP

The sum of the first 'n' terms of an AP, Sₙ, is given as follows;

[tex]S_n = \dfrac{n}{2} \cdot \left [2 \cdot a + (n - 1)\cdot d \right ][/tex]

(47/2)*(2*12+(47-1)*4)

The sum of the first 47 terms is therefore given as follows;

[tex]S_n = \dfrac{47}{2} \cdot \left [2 \times 12 + (47 - 1)\times 4 \right ] = 4,888[/tex]

The sum of the first 47 terms of the series, 12, 16, 20, ... S₄₈ = 4,888

Answer:

Yes because you could use due 7 + 8 to get 15 which is the easy way to blend with the 15 to get 30

Answer:

1)  θ = 130°

2)  θ = 310°

Step-by-step explanation:

We want to find a value of θ such that:

sin(θ) = sin(50°)

We know that sin(90°) = 1

We will have a symmetry around 90°.

Then if we define a constant k

sin(90° + k) = sin(90° - k)

we can define k such that:

90° - k = 50°

90° - 50° = k

40° = k

Then:

sin(90° + 40°) = sin(90° - 40°)

sin(130°) = sin(50°)

then θ = 130°

Now we want to find:

cos(θ) = cos(50°)

We know that cos(0°) = 1

Then we have symmetry around 0°

With the same reasoning than before, we can write:

cos( 0° + k) = cos(0° - k)

We can define:

0° + k = 50°

k = 50°

Then:

cos(50°) = cos(-50°)

But we want  0° < θ < 360°

Knowing that the peridisity of the trigonometric functions is of 360° then:

cos(50°) = cos(-50°) = cos( - 50° + 360°)

cos(50°) = cos(310°)

in this case θ = 310°
