I need help ASAP plzzzzzz

Answer:

(-∞, 5 U 7 , ∞)

Step-by-step explanation:

Given the inequality expressions

d – 4 > 3 or d – 4 < 1

For d - 4 > 3

Add 4 to both sides

d-4 + 4 > 3 + 4

d > 7

7 < d

this means that d is greater than 7,

(7 , ∞)

For d - 4 < 1

Add 4 to both sides

d - 4 + 4 < 1 + 4

d < 5

This means d is less than 5

(-∞, 5)

The required solution is (-∞, 5 U 7 , ∞)

Answer:

88

Step-by-step explanation

Answer:

area = 88 m²

Step-by-step explanation:

area = ½(b1 + b2)h

area = ½(10 m + 6 m)(11 m)

area = 88 m²

Answer:

A^2 + B^2=C^2

21^2 + 28^2= c/c

For the second answer its just backwards.

Answer:

<U+<V +< W = 180°[sum of interior angle of a triangle is 180°]

3x+9° +30° + 24° = 180°

3x + 45° = 180°

3x = 180° -45° = 135°

x = 135/3

x = 45°

Answer: I could be wrong but it's probably 3.

Step-by-step explanation: Once there's x in the 3 sides of angles you subtract. 73 minus 3 = 3 degrees. If I'm wrong sorry about that. I will try to improve. :)

Answer:

37°

Step-by-step explanation:

70°+73°+x°=180°

143°+x°=180°

x°=180°-143°

x°=37°

Answer:

Step-by-step explanation:

A (1 ,7) ,   B(4, 2),  C(-1, -1) and D(-4, 4)

Find the distance of sides using distance formula.

Distance = [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

A (1 ,7) ,   B(4, 2)

[tex]AB = \sqrt{(4-1)^{2}+(2-7)^{2}}\\\\ =\sqrt{3^{2}+(-5)^{2}}\\\\ \\ = \sqrt{9+25}=\sqrt{34} units\\\\\\\\BC = \sqrt{(-1-4)^{2}+(-1-2)^{2}}\\\\ =\sqrt{(-5)^{2}+(-3)^{2}} = \sqrt{25+9}=\sqrt{34} units\\\\\\CD = \sqrt{(-4-[-1])^{2}+(4-[-1])^{2}}\\\\=\sqrt{(-4+1)^{2}+(4+1)^{2}}\\\\=\sqrt{(-3)^{2}+(5)^{2}}\\\\=\sqrt{9+25} = \sqrt{34} units\\\\\\AD = \sqrt{(-4-1)^{2}+(4-7)^{2}}\\\\=\sqrt{(-5)^{2}+(-3)^{2}} =\sqrt{25+9} = \sqrt{34} units[/tex]

AB = BC = CD = AD = √34 units. so , ABCD is  a square.

Area of square = side * side

                          = √34 * √34

                          = 34 square units

Answer:

The value of the test statistic and its associated p-value at the 5% significance level are -1.54 and 0.9382, respectively.

Step-by-step explanation:

A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.16.

This means that the null hypothesis is:

[tex]H_{0}: p \geq 0.16[/tex]

Testing this hypothesis, means that the alternate hypothesis is:

[tex]H_{a}: p > 0.16[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

0.16 is tested at the null hypothesis:

This means that [tex]\mu = 0.16, \sigma = \sqrt{0.16*0.84}[/tex]

In a sample of 200 graduates, 24 students have a GPA of 3.00 or below.

This means that [tex]n = 200, X = \frac{24}{200} = 0.12[/tex]

Value of the test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.12 - 0.16}{\frac{\sqrt{0.16*0.84}}{\sqrt{200}}}[/tex]

[tex]z = -1.54[/tex]

Pvalue:

The pvalue is the probability of finding a sample mean above 0.12, which is 1 subtracted by the pvalue of z = -1.54.

Looking at the z-table, z = -1.54 has a pvalue of 0.0618

1 - 0.0618 = 0.9382

The value of the test statistic and its associated p-value at the 5% significance level are -1.54 and 0.9382, respectively.

Answer:

0.3504 = 35.04% probability that a worthy proposal is disapproved by both panels

Step-by-step explanation:

We have that:

0.27 = 27% of the time, the proposal is judged worthy of funding by the first panel. So 100 - 27 = 73% probability of being disapproved.

52% of the time, the independent panel reverses the decision. So if the first panel disapproves the funding, 52% probability the second approves the funding and 100 - 52 = 48% probability it does not.

What is the probability that a worthy proposal is disapproved by both panels?

48% of 73%. So

0.48*0.73 = 0.3504

0.3504 = 35.04% probability that a worthy proposal is disapproved by both panels

Answer:

[tex]y=\frac{1}{13} x+\frac{32}{13}.[/tex]

Step-by-step explanation:

1. the midpoint of the side AC is:

[tex]D:(\frac{3-2}{2};\frac{4+1}{2})=(0.5;2.5).[/tex]

2. if the coordinates of the points B and D are (7;3) and (0.5;2.5) respectively, then it is possible to make up the required equation of the median BD:

[tex]\frac{x-7}{7-0.5}=\frac{y-3}{3-2.5}; \ \frac{x-7}{13}=\frac{y-3}{1}[/tex]

or

[tex]y=\frac{1}{13} x+\frac{32}{13}[/tex]

Answer:

Jose will have played the guitar for 9.1 hours during those 6 days.

Step-by-step explanation:

Given that this week Jose played guitar for 3/4 of an hour on Tuesday, an hour and a half on Thursday, and 2.3 hours on Saturday, to determine, if Jose plays guitar for the same amount of time next week, how many hours will he have practiced over these 6 days, the following calculation must be performed:

3/4 = 0.75

1/2 = 0.5

(0.75 + 1.5 + 2.3) x 2 = X

4.55 x 2 = X

9.10 = X

Therefore, Jose will have played the guitar for 9.1 hours during those 6 days.

Answer:

  A, D

Step-by-step explanation:

The figure looks symmetrical, but their is no given information indicating it actually is symmetrical. Thus we can't make any statements about the segment lengths. Nor is there any indication that any of the arc lengths are identical.

If we rule out statements about segments and arcs, that only leaves statements about angles. As it happens both of those are true: inscribed angles that intercept the same arc are congruent.

The true statements are ...

  A: ∠CAD≅∠CBD

  D: ∠ACB≅∠ADB

Answer:

The circumference of a circle is the distance around the outside of the circle

Hope It Helps :)

Step-by-step explanation:

Answer:

Circumference of the circle or perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of circle defines the region occupied by it. If we open a circle and make a straight line out of it, then its length is the circumference. It is usually measured in units, such as cm or unit m.

When we use the formula to calculate the circumference of the circle, then the radius of the circle is taken into account. Hence, we need to know the value of the radius or the diameter to evaluate the perimeter of the circle.

Circumference of a Circle Formula

The Circumference (or) perimeter of a circle = 2πR

where,

R is the radius of the circle

π is the mathematical constant with an approximate (up to two decimal points) value of 3.14

Again,

Pi (π) is a special mathematical constant; it is the ratio of circumference to diameter of any circle.

where C = π D

C is the circumference of the circle

D is the diameter of the circle

For example: If the radius of the circle is 4cm then find its circumference.

Given: Radius = 4cm

Circumference = 2πr

= 2 x 3.14 x 4

= 25.12 cm

Answer:

AB = 7.10

Step-by-step explanation:

Reference angle = 65°

Hypotenuse = AB = ?

Adjacent side length = BC = 3

Apply the trigonometric ratio CAH, to find AB.

Cos 65 = Adj/Hyp

Cos 65 = 3/AB

AB*Cos 65 = 3

AB = 3/Cos 65

AB = 7.09860475

AB = 7.10 (nearest hundredth)

Answer:

142 square meters

Step-by-step explanation:

     Big rectangle    Area =  LxW  =      18 x9= 162

White triangle  Area   A =   (ab)/2      legs 5 and 8   ( 18-10= 8 )

= (5x8)/ 2  = 20

Subtract white triangle from green  rectangle

 162-20 = 142

    OR

area  left  rectangle    LxW     10x9 = 90

area  right rectangle    LxW       4x8 =32

area green triangle ( sides 5 an8 )   (ab)/2  =   20

90+32+20 =  142
