Answer:

In Step 2 the expression is Option 4 is correct.                                    

Step-by-step explanation:

Given : Sydney applied the steps below to find the product of (3.1)(-1.6).

To find : Which expression correctly fills in the blank in Step 2?

Solution :

Step 1 : Commutative property applied, ab=ba

(3.1)(-1.6)=(-1.6)(3.1)

Step 2 - Apply distributive property a(b+c)=ab+ac by re-write 3.1=3+0.1

(3.1)(-1.6)=(-1.6)(3+0.1)

(3.1)(-1.6)=(-1.6)(3)+(-1.6)(0.1)

Step 3 - Solve the multiple,

(3.1)(-1.6)=(-4.8)+(-0.16)

Step 4 - Add the terms,

(3.1)(-1.6)=-4.96

Therefore, In Step 2 the expression is Option 4 is correct.

A blind taste test will be conducted with 9 volunteers to determine whether people can taste a difference between bottled water
Aloiza [94]

Answer:

The answer is \frac{1}{256}

Step-by-step explanation:

If we assume that people cannot taste a difference between bottled water, then the probability of identifying tap water is 0.5

Thus, P(identify tap water)=0.5

The probability that at least 8 of the 9 people identify the tap water correctly is the sum of the probabilities

  • 8 of 9 people identified correctly or
  • 9 of 9 people identified correctly

Since P(identify tap water)=0.5 each probabilities are the same and equal to

0.5^9 =\frac{1}{512}

So we have 2*\frac{1}{512} = \frac{1}{256}

Find the lateral surface area of the figure.
Brut [27]

Surface area of the cylinder = 816.4 sq. ft.

Solution:

Height of the cylinder = 21 ft

Diameter of the cylinder = 10 ft

Radius of the cylinder = 10 ÷ 2 = 5 ft

Use the value of \pi = 3.14

Surface area of the cylinder = 2 \pi r h+2 \pi r^{2}

Substitute the given values in the surface area formula, we get

Surface area of the cylinder $=2\times3.14\times 5\times 21+2 \times3.14\times 5^2

                                               =659.4+157

                                               =816.4 ft²

Hence the surface area of the cylinder is 816.4 sq. ft.

The sum of three consecutive intergers is 267. What is the largest integer
Alisiya [41]

Answer:

90

Step-by-step explanation:

Let the starting number be x, the two consecutive numbers after x is gonna be x+1 and x+2.

If the sum of these three numbers is 267 then:

x+(x+1)+(x+2)=267

Solve

3x+3=267

3x=267-3

3x=264

x=264/3

x=88

x+1=89

x+2=90

Your three consecutive numbers are 88, 89, and 90.

The largest one of them is 90.
