How many tbsp in 1 pint

Answers

Answer:

There are 32 tablespoons in a pint

Answer:

Step-by-step explanation:

1 cup = 240 mL

1 pint = 2 cups = 480 mL

1 tbsp = 15 ml

1 pint = 480 mL / 15 tablespoons

1 pint = 32 tablespoons.

These numbers are approximations. It depends on what your conversions really are. However the answer should be very close to 32 tablespoons.

Then ? cm = 6m

Since cm is smaller than m, cm would need more to be equal or equivalent to m. Therefore we say, what multiply by 1m gives you 6m? Because they are asking for 6m. Whatever you do to one side you do to the other.

The two angles are supplementary, so their measures add to 180º. Use this to solve for x :

There are [tex]9[/tex] tens in [tex]192[/tex].

The system or method of writing certain numbers with the help of some rules is called a number system.

we write these numbers using periods.

example of the national number system is [tex]23, 56, 78, 999[/tex] that it is read as twenty-three crore fifty-six lakhs seventy-eight thousand nine hundred ninety-nine.

example of an international number system is [tex]456,456[/tex]  , read as four hundred fifty-six thousand four hundred fifty-six.

On expanding [tex]192[/tex] we  get ;

A radioactive element has a half-life of six days. What is the approximate decay rate of the element after the first day?
0.9%
1.5%
8.3%
10.9%

Answers

Answer:    8.3 or C  

Eplanation: This is because a half life is 50 percent of a normal life so 50 percent divided by 6 is 8.3

[tex]8.3[/tex]% is the approximate decay rate of the element after the first day.

What is Radioactive decay ?

Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles.

What is decay rate?

The rate of decay, or activity, of a sample of a radioactive substance is the decrease in the number of radioactive nuclei per unit time.

According to question, a radioactive element has a half-life of six days.

A half- life is [tex]50[/tex]% of a normal life.

So, the approximate decay rate of the element after the first day

[tex]=\frac{50}{6}[/tex]% [tex]=8.3[/tex]%

Hence, we can conclude that [tex]8.3[/tex]% is the approximate decay rate of the element after the first day.

We discovered that 650 GSS respondents in 2006 watched television for an average of 2.98 hrs/day, with a standard deviation of 2.4 hours. Answer the following questions, assuming the distribution of the number of television hours is normal. What is the Z score for a person who watches more than 8 hrs/day. What proportion of people watch 5 hrs/day or more television? How many does this correspond to in the sample? What number of television hours per day corresponds to a Z +1. What is the percentage of people who watch between 1 and 6 hours of television per day? Please round to a whole number

Answers

Answer:

a) 2.09167

b) 0.2

c) 130 correspondents

d) 5.38 hours per day

e) 69%

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

Mean = 2.98hrs/day, Standard Deviation = 2.4

a) What is the Z score for a person who watches more than 8 hrs/day.

z = 8 - 2.98/2.4

= 2.09167

b) What proportion of people watch 5 hrs/day or more television?

z = 5 - 2.98/2.4

z = 0.84167

Determining the Probabilityvalue from Z-Table:

P(x<5) = 0.80001

The proportion of people watch 5 hrs/day or more television

P(x>5) = 1 - P(x<5) = 0.19999

Approximately = 0.2

c) How many does this correspond to in the sample?

From the question above, we are told that: there are 650 GSS respondents in 2006 watched television

Hence the proportion that corresponds to Question b is

0.2 × 650

= 130 correspondents

Therefore, 130 correspondents watch 5 hrs a day or more television

d) What number of television hours per day corresponds to a Z = +1.

z score formula is given as:

z = (x-μ)/σ

Z = +1

x = unknown

Mean = 2.98

Standard deviation = 2.4

Hence:

1 = x - 2.98/2.4

Cross Multiply

1 × 2.4 = x - 2.98

2.4 = x - 2.98

2.4 + 2.98 + x

= 5.38 hours per day.

e)What is the percentage of people who watch between 1 and 6 hours of television per day?

For x = 1

z = 1 - 2.98/2.4

z = -0.825

Probability value from Z-Table:

P(x= 1) = 0.20469

For x = 6

z = 6 - 2.98/2.4

z = 1.25833

Probability value from Z-Table:

P(x = 6) = 0.89586

The percentage of people who watch between 1 and 6 hours of television per day is calculated as:

P(x = 6) - P(x = 1)

0.89586 - 0.20469

= 0.69117

Converting to percentage,

0.69117 × 100%

= 69.117%

To the nearest whole number = 69%

Therefore, 69% of the people who watch between 1 and 6 hours of television per day

Let g(x)=x^2+bx+11. The point (-1,8) lies on graph of g. Find value of b.​

Answers

Answer:

b=4

Step-by-step explanation:

g(x)=x^2+bx+11

When x = -1  g(x) = 8

8 = (-1)^2 +b(-1) +11

8 = 1 -b+11

Combine terms

8 = 12-b

Subtract 12 from each side

8-12 = 12-b-12

-4 = -b

Multiply by -1

4 = b
