Answer:

I think the answer is 742,000,000

Step-by-step explanation:

The approximate number of heartbeats in the lifetime of a large dog is 742,000,000 times.

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

According to the question

A small dog’s heart beats about during its lifetime = 530,000,000 times

A large dog’s heart beats about 1.4 times this amount.

i.e A large dog’s heart beats about during its lifetime = 530,000,000 *1.4  times

                                                                                     =  742,000,000 times

Hence, the approximate number of heartbeats in the lifetime of a large dog is 742,000,000 times.

Answer:

Step-by-step explanation:

If the z statistic does not lie within the critical region, you cannot reject the null hypothesis but neither can you necessarily accept it.  

What you can do is reject the alternate hypothesis.

The valid conclusion based on the given results is; One can reject the alternate hypothesis.

We are told that;

z-statistic = 2.1

Now, the critical z-values were -1.96 and 1.96

Since our z-statistic does not lie within the critical values region, it means that there is not enough evidence to reject the null hypothesis at the given significance level. However, it means that we can reject the alternate hypothesis.

Answer:

x = 14√3

y = 7√3

Step-by-step explanation:

By applying sine rule in the given triangle,

sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{\sqrt{3} }{2}=\frac{21}{x}[/tex]

x = [tex]\frac{42}{\sqrt{3}}[/tex]

x = 14√3

By applying cosine rule in the given triangle,

cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

[tex]\frac{1}{2}=\frac{y}{x}[/tex]

[tex]\frac{1}{2}=\frac{y}{14\sqrt{3}}[/tex]

y = 7√3

Answer: 1.35

Answer:

1.35

Step-by-step explanation:

We need to identify our independent variables and dependent variables.

The number of papers graded depend on the amount of time.

The amount of time is the independent variable

The papers graded depends us the dependent variable

Divide the independent variable by the dependent variable to find papers per minute

For Ms.Mitchell the papers per minute is

For Mr.Rector, the papers per minute is

Subtract 2.4 from 3.75.

The answer is 1.35

Answer:

q = 2√14

Step-by-step explanation:

To determine the value of q, apply the leg rule/geometric mean theorem, which is:

Hypotenuse/leg = leg/part

Hypotenuse = 10 + 4 = 14

Leg = q

Part = 4

Plug in the values into the equation:

14/q = q/4

Cross multiply

q*q = 14*4

q² = 56

q = √56

q = √(4*14)

q = 2√14

Answer:

q = 2√14

Answer:

C. 215.12 feet per second

Step-by-step explanation:

Sergei's car was clocked in a quarter mile race at 146.67 miles per hour.

How many feet per second is this to the nearest hundredth if there are 5280 feet in one mile?

From the above question

1 mile = 5280 feet

1 hour = 60 minutes

1 minutes = 60 seconds

1 hour = 60 × 60 seconds = 3600 seconds

We are to convert 146.67 miles per hour = feet per second

Hence:

146.67 miles /1 ft × 5280 feet/1 miles × 1 hr/3600 seconds

= 146.67 × 5280 feet/3600 seconds

= 774417.6 feet / 3600 seconds

= 215.116 feet per second.

Approximately = 215.12 feet per second

Answer:

$117

Step-by-step explanation:

Create an equation to represent the situation, where x is the number of games he attended, and y is the cost

y = 6x + 45

Solve for the amount he paid by plugging in 12 as x

y = 6x + 45

y = 6(12) + 45

y = 72 + 45

y = 117

So, Ray paid $117
