The combined mass of the compounds is 13/12 grams

From the question, we have the following parameters that can be used in our computation:

3/4 gram sodium chloride and 1/3 gram potassium chloride

The combined mass of the compounds is then calculated as

Combined mass = sodium chloride + potassium chloride

Substitute the known values in the above equation, so, we have the following representation

Combined mass = 3/4 + 1/3

Evaluate the sum

Combined mass = 13/12

Hence, the combines mass is 13/12 grams

Step-by-step explanation:

Quadrants:

In the first quadrant, both x and y are positive, that is, x > 0 and y > 0.

In the second quadrant, y is positive while x is negative, that is, x < 0 and y > 0.

In the third quadrant, both x and y are negative, that is, x < 0 and y < 0.

In the fourth quadrant, x is positive while y is negative, that is, x > 0 and y < 0.

In this question:

x < 0 and y < 0, so third quadrant, and the correct answer is given by option D.

Answer:

1.2,080 m²

2.63m²

3.2,017

4.25m²

5.81m²

Explanation:

1. A = LW

A = 65 m × 32 m

A = 2,080 m²

2. A = LW

A = 21 m × 3 m

A = 63m²

3. A = 2,080 m² – 63 m²

A = 2,017 m²

4. A = s²

A = (5m)²

A = 25 m²

5.

A = s²

A = (9 m)²

A = 81 m²

The experimental probability of spinning a white or yellow is 7/20

From the question, we have the following parameters that can be used in our computation:

Outcomes of experiments

The outcomes of experiments are given as

yellow / 5

blue / 12

green / 8

white / 9

red / 6

The experimental probability of spinning a white or yellow can be calculated using the following equation

P(White or Yellow) =P(White) + P(Yellow)

Substitute the known values in the above equation, so, we have the following representation

P(White or Yellow) = (9 + 5)/5 + 12 + 8 + 9 + 6)

Evaluate the sum

P(White or Yellow) = 14/40

Simplify

P(White or Yellow) = 7/20

Hence, the probability is 7/20

The required probabilities are
• Exactly 2 are male = 0.08

• At least 7 are male = 0.14

• None are male = 0.60

• Less than 3 are male = 0.12

• There are 3 or 4 males = 0.019

• At least 1 is male = 0.04

Probabilities to college reported that 40% of its population is male. Nine students are selected at random.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

For Exactly 2 are male = 2 * 0.04
                                       = 0.08
Similarly,
• At least 7 are male = 0.14

• None are male = 1 -0.40 = 0.60

• Less than 3 are male = 0.12

• There are 3 or 4 males = 0.12 *0.16 = 0.019

• At least 1 is male = 0.04

Step-by-step explanation:

The total length needed in inches will be 490.5 inches.

A fraction simply means a piece of a whole. In this situation, the number is represented as a quotient such that the numerator and denominator are split. In this situation, in a simple fraction, the numerator as well as the denominator are both integers.

Since the machinist must cut 12 strips of metal that are each 3 ft 4 7/8 in. long  The total length needed in inches will be:

= (3 ft 4 7/8 inch × 12)

Note that 1 feet = 12 inches

= (12 × 3) + (4 7/8) × 12

= (36 + 4.875) × 12

2.)

B. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.02 level of significance to support the power company claim that the mean amount of electricity for their residents is more than the national average.

Step-by-step explanation:

1.)

H0 : μ = 10290

H0 : μ > 10290

n = 153, sample mean, xbar = 10586 ; population standard deviation, σ = 2509 ; α = 0.05

Test statistic:

(xbar - μ) ÷ (σ/√(n))

(10586 - 10290) ÷ (2509/√(153))

296 / 202.84062

Test statistic (Z) = 1.46

We obtain the Pvalue :

Decision Region :

Reject H0 ; if Pvalue < α

Pvalue from Z test statistic calculator :

Pvalue = 0.072

Pvalue > α ; Hence, we fail to reject the Null ; there isn't sufficient evidence to support the power company's claim

2.)

H0 : μ = 10290

H0 : μ > 10290

n = 153, sample mean, xbar = 10446 ; population standard deviation, σ = 2509 ; α = 0.02

Test statistic:

(xbar - μ) ÷ (σ/√(n))

(10446 - 10290) ÷ (2509/√(153))

156 / 202.84062

Test statistic (Z) = 0.769

We obtain the Pvalue :

Decision Region :

Reject H0 ; if Pvalue < α

Pvalue from Z test statistic calculator :

Pvalue = 0.221

Pvalue > α ; Hence, we fail to reject the Null ;
