By definition a prime number and a composite number are:

Prime numbers: whole numbers greater than 1, that have only two factors: 1 and the number itself.

Composite numbers: whole numbers greater than 1, that have more than two factors. It is divisible by the number itself, the number 1 and at least one other number.

In that order, 1 is not a prime number and -600 is not a composite number. Options c and e are false.

Now, we need to check 443, 541 and 591.

To check if a number is prime or composite, we have to apply divisibility tests and check if the number is divisible by 2, 5, 3, 11, 7 or 13.

The divisibility rules for these numbers are:

2: If the last digit is an even number.

These numbers are odd, then they are not divisible by 2.

3: a number is completely divisible by 3 if the sum of its digits is divisible by 3.

4+4+3=11 it is not divisible by 3

5+4+1=10 it is not divisible by 3

5+9+1=15 and 1+5=6 it is divisible by 3, then 591 is not a prime number (option d is false).

5: a number is divisible by 5 if the last digit is 0 or 5.

443 and 541 are not divisible by 5.

11: take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number:

443-> 4-4+3=3 it is not divisible by 11

541->5-4+1=2 it is not divisible by 13

13: to check if a number is divisible by 13, we have to add four times of the last digit of the number to the remaining number and repeat the process until you get a two-digit number. Now check if that two-digit number is divisible by 13 or not. If it is divisible, then the given number is divisible by 13.

44+(3*4)=44+12=56 it is not divisible by 13

54+(1*4)=54+4=58 it is not divisible by 13.

Then, 443 and 541 are both prime numbers, then the answer is b. 541 is a prime number.

Answer:

4) 7a+20

5) 14+2b

6) 25c² - 15

Step-by-step explanation:

4) 9a+7-2a+13= 9a-2a+7+13 = 7a+20

5) 21-3b+5b-7= 21-7+5b-3b = 14+2b

6) (3c)² + (8c)² - 15 = 9c² + 16c² - 15 = 25c² - 15

The required probability of the spinner not landing on a number divisible by 3 is 11/16.

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

Here,
For spinners numbered from 1 to 16,
Total sample space = 16
Favorable event = 3, 6, 9, 12, 15
Total number of favorable events = 5
Now,
Probability of the spinner not landing on a number divisible by 3,
= 1 - 5 / 16
= 11 / 16

Thus, the spinner's needed probability of not landing on a number divisible by 3 is 11/16.

False. the student’s t statistic for testing the significance of a binary predictor can be greater than 0.

The t-statistic is used for testing the significance of a regression coefficient in a linear regression model. A binary predictor (also known as a dummy variable or indicator variable) has only two possible values (0 or 1), and its coefficient can be tested using a t-test. However, the t-statistic can never be greater than 0 because it measures the difference between the estimated coefficient and its hypothesized value (usually 0), divided by its standard error. If the estimated coefficient is greater than the hypothesized value, the t-statistic will be positive. If it is less than the hypothesized value, the t-statistic will be negative. But it can never be greater than 0.

The term of the loan is 0.447 years

The simple interest formula states that interest is equal to the principal times the rate times the time.

Interest, I = PRT

Where,

I = Interest

P = Principal

T = Time

From the question,

Principal= 1813.25

rate = 9.3

Interest = 75.42

Therefore,

Interest = (principal × rate × time)/100

Substitute the values,

75.42 = ( 1813.25 × 9.3 × t)/100

Solve the equation for t,

t = 0.447 years

The remainder when h(x) is divided by (x+1) is 69.

We have:

h(-1) = 2(-1)^4 - 17(-1)^3 + 30(-1)^2 + 64(-1) + 10 + 69 = 54

To evaluate the polynomial h(x) at x=-1 using the remainder theorem, we need to find the remainder when h(x) is divided by (x+1).

We can use polynomial long division or synthetic division to perform this division. Here's the polynomial long division:

          2x^3 - 19x^2 + 49x - 59

   ---------------------------------

x + 1 | 2x^4 - 17x^3 + 30x^2 + 64x + 10

   - (2x^4 + 2x^3)

     ---------------

           -19x^3 + 30x^2

           + (-19x^3 - 19x^2)

           -------------------

                       49x^2 + 64x

                       + (49x^2 + 49x)

                       -------------

                                   -59x + 10

                                   - (-59x - 59)

                                   -------------

                                                69

Therefore, the remainder when h(x) is divided by (x+1) is 69.

Hence, we have:

h(-1) = 2(-1)^4 - 17(-1)^3 + 30(-1)^2 + 64(-1) + 10 + 69 = 54

Answer:

white sold = 16

yellow sold = 12

Step-by-step explanation:

w = # of white sold

y = # of yellow sold

w + y = 28   solve this for w

w = 28 - y

9.95w + 13.5y = 321.20     substitute w = 28-y into this expression and solve for y

9.95(28-y) + 13.5y = 321.20

278.60 - 9.95y + 13.50y = 321.20

278.60 + 3.55y = 321.20

3.55y = 321.20 - 278.60 = 42.60

y = 42.60/3.55 = 12   substitute this into w = 28 - y and solve for w

w = 28 - 12 = 16

Answer:

La cantidad de dinero en:

Primer bolsillo = x = 200 euros

Segundo bolsillo = 2x = 400 euros

Step-by-step explanation:

Nos dijeron:

En un bolsillo tengo una cantidad de dinero y en el otro tengo el doble.

Representemos, la cantidad de dinero en el:

Primer bolsillo = x

Segundo bolsillo = 2x

En total tengo 600.

Por eso:

x + 2x = 600

3 veces = 600

x = 600/3

x = 200

2x = 200 × 2

x = 400

Por lo tanto, la cantidad de dinero en:

Primer bolsillo = x = 200 euros

Segundo bolsillo = 2x = 400 euros

Step-by-step explanation:

Specifically 9.05, but simplified 9.

We conclude that less than 30% of teen girls smoke to stay thin.

Let p be the percentage of teen girls who smoke to stay thin.

So, the Null Hypothesis,(\(H_{0}\)):

p≥ 30%

This means that at least 30% of teen girls smoke to stay thin

Alternate Hypothesis,(\(H_{A}\)) :

p < 30%

This means that less than 30% of teen girls smoke to stay thin.

The test statistics that would be used here

One sample z proportion statistics:

T.S = p' - p/ \(\sqrt{p'(1-p')/n}\) ≈N( 0,1)

Here p'= sample percent of teen girls who smoke to stay thin = 63/ 273 = 0.231

n = number of sample of teen girls = 273

Now putting these values we have:

Test statistics = 0.231 - 0.30/ \(\sqrt{0.231( 1- 0.231)/ 273}\)

                      = -2.705

So we get the value of z-test statistics as - 2.705.

As there is not provided in the question that the level of significance so we assume it to be 5%. Now at a 5% significance level, the z table gives the critical value of -1.645 for left- the tailed test.

As test statistics is less than the critical value of z that is -2.705< -1.645. So we reject our null hypothesis as will fall in reject our null hypothesis as it will fall in the rejection region due to which we reject our null hypothesis.

Therefore we get that less than 30% of teen girls smoke to stay thin.

The area and circumference of the given circle are 200.96 cm2 200.96 c m 2 and 50.24 cm 50.24 c m respectively.

Circumference of circle:

In geometry, a circumference is the circumference of a circle or an ellipse. That is, the circumference will be the length of the arc of the circle as if it were open and straight to the line segment. More generally, the perimeter is the length of the curve around any closed figure. The circumference can also designate the circle itself, the trajectory corresponding to the edge of a disk. The circumference of a sphere is the circumference or length of one of its great circles.

Area of circle:

The area of ​​a circle is the space the circle occupies in a two-dimensional plane. Alternatively, the space occupied inside the boundary/perimeter of a circle is called the area of ​​the circle. The formula for the area of ​​a circle is A = πr2, where r is the radius of the circle. Area unit is square unit, such as m2, cm2, in2, etc.

According to the Question:

The circumference C of a circle with radius r is given by

C = 2πr

where the units of C will be the same as the unit of R.

The problem tells us that the radius r = 8m.

And, we will say π = 3.14

So,

C = 2(3.14)(8) = 50.24m

The units are meters.

Now, the area A of a circle with radius r is given by

A = πr², where the units of A will be the units of r squared.

Again,

we know r = 8,π = 3.14, so

A= 3.14(8²)

8² = 8⋅8 = 64,

Thus,

A= 64(3.14) = 200.96m²
