Answer:

The value of x is 108°

Step-by-step explanation:

Given interior angles of parallelogram are:

$\frac{2}{3}x, x, \frac{2}{3}x\ and x$

<u>The sum of interior angles of a parallelogram is 360°.</u>

We will use this information to find the value of x.

So adding up all the angles and putting the sum equal to 360 we get,

$x+\frac{2}{3}x+x+\frac{2}{3}x = 360$

$2x+\frac{2}{3}x+\frac{2}{3}x = 360\\2x + \frac{4}{3}x = 360$

Taking LCM on left side of the equation, as it involves fraction

$\frac{6x+4x}{3} = 360\\\frac{10x}{3} = 360$

Multiplying both sides by 3

$\frac{10x}{3} * 3 = 360 * 3\\10x = 1080$

Dividing both sides by 10

$\frac{10x}{10} = \frac{1080}{10}\\x = 108$

Hence,

The value of x is 108°

A person's blood glucose level and diabetes are closely related. let x be a random variable measured in milligrams of glucose pe

fenix001 [56]

Let x be the number of adults (under 50 years old) after a 12-hour fast where X ~ N(85,25)

The problem is missing some parts but here are the answers:

(a) x is more than 60

z(60) = (60-85)/25 = -1

P(x > 60) = P(z > -1) = 0.158655

(b) x is less than 110
z(110) = (110-85)/25 = 1

P(x < 110) = P(z < 1) = 0.841345

If f(x) = -3x + 1, find f(1) - 1

Amiraneli [1.4K]

Answer:

f(1) - 1 = -3

Step-by-step explanation:

Step 1: Find f(1)

f(1) = -3(1) + 1

f(1) = -3 + 1

f(1) = -2

Step 2: Find f(1) - 1

f(1) - 1 = -2 - 1

f(1) - 1 = -3

LOTS OF POINTS!?!?!?Write a linear function f with the values f(5)=−1 and f(0)=−1.<br> f(x)=

Brut [27]

Answer:

The euation of the linear function is:

y = -1

Step-by-step explanation:

As the function has the values

at x = 5, f(5) = -1

at x = 0, f(0) = -1

Thus, the two points are:

(5, -1)

(0, -1)

Finding the slope between (5, -1) and (0, -1)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(0,\:-1\right)$

$m=\frac{-1-\left(-1\right)}{0-5}$

$m=0$

We know that the slope-intercept form of the line equation is

y=mx+b

where m is the slope and b is the y-intercept

We also know that the y-intercept can be computed by setting x=0 and finding the corresponding value of y.

so at x = 0, y = -1

Thus, the y-intercept 'b' = -1

Now, substituting m = 0 and b = -1 in the slope-intercept form of the line equation

y = mx+b

y = 0x + -1

y = -1

Therefore, the euation of the linear function is:

y = -1
