Answer:

The answer to your question is:

x = -10; y = 8

Step-by-step explanation:

Solve equations by elimination method

2x + 3y = 4 (1)

x + 2y = 6 (2)

Multiply 2 by -2

2x + 3y = 4

-2x - 4y = -12

-y = -8

y = 8

Substitute y in (2)

x + 2(8) = 6

x = 6 - 16

x = -10

Use the given values of n an p to find the minimum usual value mean - 2standard deviations and the maximum usual value. N= 1056,

SCORPION-xisa [38]

Answer:

The minimum usual value: 818.803

The maximum usual value: 870.797

The population mean: 844.8

The standard deviation: 12.9985

Step-by-step explanation:

The parameters provided for the Binomial Distribution are:

n=1056, p=0.80

The population mean can be computed as:

μ = n ⋅ p

= 1056 × 0.80 = 844.8

The population variance is obtained by:

σ² = n ⋅ p ⋅ (1 − p)

= 1056 × 0.80 × 0.2 = 168.96

The standard deviation can be computed by taking the squared root of the variance:

σ = $\sqrt{n.p.(1-p)}$

= $\sqrt{168.96}$

= 12.9985

The minimum usual value: μ - 2σ = 844.8 - 2(12.9985)

= 844.8 - 25.997

= 818.803

The maximum usual value: μ + 2σ = 844.8 + 2(12.9985)

= 844.8 + 25.997

= 870.797

Alicia is making a triangular sign for the school play. The area of the sign is 558 in. The base of the triangle is 36in. What i

Pie

To find the height of the triangle you will use the formula to find the area of the triangle and the information provided about the area and the base length.

A= 1/2 bh
558 = 1/2 x 36 x h
558 = 18 x h

To solve for the height divide both sides by 18.

This leaves you with 31 = h.

So, the height is 31 inches.

Answer:

Step-by-step explanation:

Right off the bat, you will know the lowest number is 52 and the highest number is 65, therefore there will act as the guides for your box and whisker plot. This eliminates answers B and C because they are not accurate to that.

Next, we find the median of the set of numbers by crossing out (writing it down, or imagining doing so) the numbers on either end consecutively to until you reach the center number, ours being 58. This eliminates answer A.

This leads us to belive answer D is the correct box and whisker plot.

Mike was in charge of a special sports day at the Community Center. A company donated 50 boxes of ice cream bars, with 12 bars i

Anna007 [38]

The right answer is Option D.

Step-by-step explanation:

Boxes of ice cream received = 50

Ice-creams in each box = 12

Total ice-cream bars = No. of boxes * Ice cream bars in each box

Total ice-cream bars = $12*50=600$

No. of people who had ice cream bars = 520

Ice-cream bars left = Total ice cream bars - No. of people who had ice cream

Ice cream bars left = $600-520=80$

80 ice cream bars were left.

The right answer is Option D.
