Answer:

You can't get 435 with addition

Step-by-step explanation:

But if you can use multiplication and addition

50 times 5 = 250

250 plus 50 = 300

300 plus 100 = 400

400 plus 25 = 425

425 plus 10 = 435

Answer:

50*6 + 100 +25 + 10 =435

Step-by-step explanation:

The required area of new rectangle is 600 square meters.

A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.

Let the length of the rectangle = x cm,

And width of rectangle = y cm.

Given that,

The area of rectangle is 24 square centimeters.

The area of rectangle = length × width

xy = 24       (1)

When length and width are multiplied by 5,

The length becomes 5x and width becomes 5y,

The area of new rectangle = 5x × 5y

= 25 xy

Substitute the values of xy from equation (1),

Area = 25 × 24 '

        = 600

The area of new rectangle is 600 square centimeters.

8% of 550 is 44

44 + 550 = 594

Answer:

D) $594

550 x 1.08 = 594. You're multiplying by 1.08 because of the 8% tax added onto the original price.

Answer:

x = 75

Step-by-step explanation:

1. Find the inner angle (opposite from where x is), using the outer angle of 150.

Note: these two angles are supplementary, meaning that they add up to 180 degrees.

Since the outer angle is 150, the inner angle is 30 degrees because 150+30 = 180.

2. Find the other two angles to get x.

The red markings on the two sides of the triangle indicate that this is an isocoleses triangle. Isocoleses triangles have two congruent angles. This means that the remaining two angles will be the same.

With that in mind, recall what I said about the angles being supplementary. All angles in a triangle add up to 180. So, use the following equation and solve for x.

2x + 30 = 180 (Subtract 30 from both sides)

2x = 150 (divide by 2)

x = 75

3. x = 75

Answer:

X = 65 degrees

Step-by-step explanation:

180 - 150 = 30 the angle beside the 150 degrees

180 - 30 = 130    180 degrees is the sum of all three angles in a triangle

130/2 = 65    since both sides are equal the other 2 angles are the same

Answer:

x = 59

Step-by-step explanation:

180 = 73 + x + (x-11)

180 - 73 + 11 = 2x

118 = 2x

x = 118/2

x = 59

Answer:

SSS (Side Side Side)

The simplest way to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those triangles must also be congruent. This method is called side-side-side, or SSS for short.

SAS (Side-Angle-Side)

A second way to prove the congruence of triangles is to show that two sides and their included angle are congruent. This method is called side-angle-side. It is important to remember that the angle must be the included angle--otherwise you can't be sure of congruence. When two sides of a triangle and the angle between them are the same as the corresponding parts of another triangle there is no way that the triangles aren't congruent. When two sides and their included angle are fixed, all three vertices of the triangle are fixed. Therefore, two sides and their included angle is all it takes to define a triangle; by showing the congruence of these corresponding parts, the congruence of each whole triangle follows.

Answer:

0.11507

Step-by-step explanation:

Given that:

Mean (m) = 25

Standard deviation = 5

Proportion of subject in the population with score above 31

P(x > 31)

Obtain the standardized score of x = 31

Zscore = (x - m) / s

Zscore = (31 - 25) / 5

Zscore = 6 / 5

Zscore = 1.2

Hence, p(Z > 1.2)

Using the Z probability calculator :

p(Z > 1.2) = 0.11507

Answer:

y = 3.584

Step-by-step explanation:

Given

Variation = Inverse Proportional

When y = 7, x = 4

Required

Find y when x = 5

First, we need to represent the variation.

y varies inversely proportional to x³

This implies that

y ~ 1/x³

Convert variation to equation

y = k/x³

Make k the subject

k = x³y

When y = 7, x = 4

This gives:

k = 4³ * 7

k = 64 * 7

k = 448

To determine the value of y when x = 5;

We make use of y = k/x³

Substitute 5 for x and 448 for k

y = 448/5³

y = 448/125

y = 3.584

Answer:

a)  P(exactly two defectives) = 0.2734

b) N [tex]\simeq[/tex] 55

Step-by-step explanation:

From the given information:

P(exactly two defectives) = P(X =2) = [tex]^{100}C_2 \times ( 0.02)^2 \times(1-0.02)^{100-2}[/tex]

[tex]= \dfrac{100!}{2!(100-2)!} \times ( 0.02)^2 \times(0.98)^{98}[/tex]

[tex]= 4950 \times 4 \times 10^{-4} \times 0.1380878341[/tex]

= 0.2734

Thus, P(exactly two defectives) = 0.2734

b)

To find:

P(X ≥ 1 )

let X be the random variable that obeys a binomial distribution, X represents the number of defectives,

∴

[tex]X \sim B ( N, 0.02)[/tex]

[tex]P(X \ge 1 ) = 1 - P(X < 1) \\ \\ P(X \ge 1 ) = 1 - P(X = 0)[/tex]

[tex]0.6676 = 1 - ^NC_0 \times (0.02)^0 (0.98)^N[/tex]

[tex]0.6676 = 1 - (0.98)^N[/tex]

[tex](0.98)^N = 1 - 0.6676[/tex]

[tex](0.98)^N = 0.3324[/tex]

N log (0.98) = log (0.3324)

[tex]N = \dfrac{log \ 0.3324}{log \ 0.98}[/tex]

N = 54.51824841

N [tex]\simeq[/tex] 55
