6 0

Answer:

A) defined by the two parameters μ = 0, σ =1

(B) symmetric

(D) a density curve.

(E) unimodal

(F) referred to as a bell-curve

Step-by-step explanation:

We have to state the properties of a standard normal distribution.

A) defined by the two parameters μ = 0, σ =1

The standard normal distribution has a mean 0 and standard deviation of 1.

(B) symmetric

The normal distribution is symmetric around the mean that is area under the curve on the left side of mean is same as the area on the right side of mean.

(C) defined by the two parameters μ = 1, σ = 0

The given statement is false in regard with standard normal distribution.

(D) a density curve.

A density curve is a curve that represents the probability for a distribution and area under the curve is 1. The standard normal distribution is a density curve.

(E) unimodal

The standard normal distribution is unimodal that is it have only one value that occurs most frequently and for standard normal distribution the modal value is 0.

(F) referred to as a bell-curve

The standard normal distribution curve has a shape similar to a bell and referred to as bell-curve.

(G) skewed

The standard normal distribution is not skewed. It is symmetric.

(H) multimodal

The standard normal distribution has a unique mode.

Help me pls... ....

Step-by-step explanation:

A1

1 yard = 3 feet

1 foot = 12 inches

therefore,

100 yards = 100×3×12 inches = 3600 inches

A2

again, 1 yard = 3 feet

8 ft = 8/3 = 2.67 yards = 2 2/3 yards

A3

1 gallon = 8 pints

A4

1 liter = 1000 milliliters (remember, "mili" means 1/1000).

therefore,

2.2 liters = 2.2×1000 = 2200 milliliters

A5

again, 1 liter = 1000 milliliters

therefore

1 milliliter = 1/1000 liter

670 milliliters = 670 × 1/1000 liter = 670/1000 liter =

= 0.67 liter

B1

1 kg (kilogram) = 1000 grams ("kilo" means 1000).

we have 3 layers.

each layer weighs (cake plus icing)

1/2 kg + 100 g = 500 g + 100 g = 600 g

3 layers then weigh

3×600 g = 1800 g

the additional candle weighs 250 g.

so, the total is

1800 g + 250 g = 2050 g = 2.05 kg

B2

area is 110 m².

1 m = 100 cm ("centi" means 1/100).

and 1 m² is then 100×100 = 10000 cm².

so, the area in cm² is

110 × 10000 = 1,100,000 cm²

the top area of one brick = 10 × 20 = 200 cm²

so, we need

1,100,000 / 200 = 11,000 / 2 = 5500 bricks
