Answer:

x=50

y=40

p=130

Step-by-step explanation:

A whole circle is 360 degrees, so 270+40+x = 360. x=50.

Y is the same angle as the 40 degrees above it.

P is the same as y+90, so it's 40+90 = 130.

Answer:

25.75 sq units

Step-by-step explanation:

Big triangle = 1/2 * 3.5 * 9 = 15.75

Tiny triangle = .5 * 2 * 2 = 2

Medium triangle = .5 * 2 * 5 = 5

square = 2 * 2

15.75 + 4 + 5 + 2

Base of parallelogram = 20 meter

Step-by-step explanation:

Given:

Area of parallelogram = 100 square meters

Height of parallelogram = 5 meters

Find:

Base of parallelogram

Computation:

Area of parallelogram = [Base of parallelogram][Height of parallelogram]

By putting value in the formula;

100 =  [Base of parallelogram][5]

Base of parallelogram = 100 / 5

Base of parallelogram = 20 meter

Answer:

[tex]\frac{9}{80}[/tex]

Step-by-step explanation:

So there is 40marbles in total

The probability of picking a red marble first is [tex]\frac{10}{40}[/tex] because there is 10 red marbles out of 40 total marbles

Then you replace it and I'm going to assume that you put the red marble back.

Then you would still have 40 marbles and the probability of picking a blue one is [tex]\frac{18}{40}[/tex] because there is 18 blue marbles.

Then you multiply [tex]\frac{10}{40}[/tex] and [tex]\frac{18}{40}[/tex] and that is [tex]\frac{9}{80}[/tex]

Hope this helps and If I'm wrong pls tell me.

Answer:

3(4x - 2.5) = 5(0.4x + 10) + 33

3•(4•x - 2.5) = 5•(0.4•x + 10) + 33

10x = 90.5

x = 181/ 20

= 9.05

Step-by-step explanation:

9514 1404 393

Answer:

  x = 9.05

Step-by-step explanation:

Start by eliminating parentheses.

  12x -7.5 = 2.0x +50 +33

  10x = 90.5 . . . . . . . . . . . . . add 7.5-2x

jdbdvfbf did ddbvdrvd d dv

Step-by-step explanation:

The endpoints of the diameter are A(-4,1) and B(4,2) . For finding the equation of circle we need to find the centre and the radius.

Coordinates of centre can be find out by the midpoint formula.

[tex] \implies Center = \bigg(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\bigg)\\\\\implies Centre = \bigg(\dfrac{-4+4}{2},\dfrac{1+2}{2}\bigg)\\\\\implies \boxed{\boxed{Centre = (0 , 1.5)}}[/tex]

Now the measure of radius can be obtained by half the distance between them.

[tex]\implies D = \sqrt{ (x_2-x_1)^2+(y_2-y_1)^2}\\\\\implies D =\sqrt{ (4+4)^2+(2-1)^2}\\\\\implies D = \sqrt{ 64 + 1 }\\\\\implies D =\sqrt{65} \\\\\implies \boxed{\boxed{ Radius = \dfrac{\sqrt{65}}{2} }}[/tex]

We know the general equation of circle as ,

[tex]\implies (x-h)^2+(y-k)^2= r^2[/tex]

[tex]\implies (x-0)^2+ (y-1.5)^2 = \bigg(\dfrac{\sqrt{65}}{2} \bigg)^2\\\\\implies x^2 + (y-1.5)^2=\dfrac{65}{4} \\\\\implies\boxed{\boxed{ 4x^2+4(y-1.5)^2 = 65 }}[/tex]

Answer:

1. Fraction = 0.36, 36% and 36/100

Using the unit circle, it is found that the value of y is given by:

[tex]x^2 + y^2 = 1[/tex]

At point P, we have that [tex]x = \frac{2}{5}[/tex], and hence, we have to find the value of y.

[tex]x^2 + y^2 = 1[/tex]

[tex]\left(\frac{2}{5}\right)^2 + y^2 = 1[/tex]

[tex]\frac{4}{25} + y^2 = 1[/tex]

[tex]y^2 = 1 - \frac{4}{25}[/tex]

[tex]y^2 = \frac{21}{25}[/tex]

[tex]y = \pm \sqrt{\frac{21}{25}}[/tex]

[tex]y = \pm \frac{\sqrt{21}}{5}[/tex]

The last side has to be less than the sum of the other 2 sides, or less than 8. The only answer choice with this is the 3rd one.

It’s :lim f(x)=85 and lim f(x)=120

The limit of the given functions f(x)=85 and lim f(x)=120.

We have given that,

Function f(x) has a jump discontinuity at x = 8.

We have to determine a statement that identifies possible one-sided limits at x = 8.

Answer:

H0 : σ²= 7.2²

H1 : σ² < 7.2

We can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.

Step-by-step explanation:

H0 : σ²= 7.2²

H1 : σ² < 7.2²

The test statistic :

X² = [(n - 1)*s² ÷ σ²]

s² = 3.5

n = sample size = 25. ; s²

X² = [(25 -1)*3.5² ÷ 7.2²

X² = (24 * 3.5^2) / 7.2^2

X² = 5.67

Pvalue from Chisquare statistic :

P(X² < 5.67) = 0.000042

Pvalue < α ; we reject the Null.

Hence, we can conclude that the mean waiting time of customers vary less, Than 7.2 minutes.
