Answer:

4.125 in decimal form and 4 1/8 in simplified fraction form

Step-by-step explanation:

The value of multiplication of an improper fraction 3/8 and a whole number 11 as a mixed number is 4 1/8.

To calculate 3/8 × 11 as a mixed number, we can follow these steps:

Step - 1:

Multiply the whole number by the numerator of the fraction:

11 × 3 = 33

Step - 2:

Divide the result by the denominator of the fraction:

33 ÷ 8 = 4 with a remainder of 1

Step - 3:

The whole number part of the mixed number is the quotient from the division:

The whole number part is 4.

Step - 4:

The fractional part of the mixed number is the remainder divided by the original denominator:

The fractional part is 1/8.

Therefore, the answer to 3/8 × 11 as a mixed number is 4 1/8.

Answer:

x=-192

Step-by-step explanation:

simplyfying we get

2/3x-4= 3/4x+12

so subratcing 2/3 on both sides we get

-4= 9x/12- 8x/12+12

subtracting 12 from both sides we get

-16= x/12

x= -192

Step-by-step explanation:

If the spinner has an even number of numbers on it, there will be an equal number of odd and even numbers, meaning that the probability of spinning an odd number is 1 2. This is also the probability of flipping heads on a coin. And so we have: 1 2 × 1 2 × 1 2 = 1 8. If the spinner has an odd number of numbers on it, the probability of spinning an odd number will vary. sorry if this isn't right have a nice day.

Answer:

There should be a larger number of trials. With 500 flips of the coin, the experimental probability will likely approach the theoretical probability of 0.5.

Answer:

17.5

Step-by-step explanation:

Those angles are supplementary, in other words, they add up to 180°

To solve you set the expressions up to 180:

(5x - 30) + 7x = 180

12x - 30 = 180

12x = 210

x = 17.5

Answer:

The length of the rectangular pen is 40ft. The width of the rectangular pen is 20ft

Answer:

7ft

Step-by-step explanation:

2W+2L=20

2(W+L)=20

2(W+(W+4))=20

4W+8=20

4W=12

W=3

or

If 20 is the total length of fencing used, the length of the fence is to be 4 ft longer than the width, and we know this is a rectangular pen (meaning it has 4 sides), we first multiply 4 (the additional ft for the length side) by two to get 8. Next we subtract 8 from the total amount of fencing (20) to get 12. Finally, since we know there are 4 sides to a rectangle, we divide 12 by 4 to get the width. Now since the length is 4 ft longer than the width, and we are looking for the length, then we add 3+4 to equal 7.

7 is the length.

Answer:

v=-5 and v=3

Step-by-step explanation:

We are given that

[tex]v^2-15=-2v[/tex]

We have to find  two solutions of quadratic equation.

[tex]v^2+2v-15=0[/tex]

Using addition property of equality

[tex]v^2+5v-3v-15=0[/tex]   (By using factorization method)

[tex]v(v+5)-3(v+5)=0[/tex]

[tex](v+5)(v-3)=0[/tex]

Substitute each factor equal to 0

[tex]v+5=0[/tex] and [tex]v-3=0[/tex]

[tex]v=-5[/tex] and [tex]v=3[/tex]

Hence, two solutions of quadratic equation are

v=-5 and v=3

Answer:

15 bags

Step-by-step explanation:

She can fill 5 bags per each pound (because there are 5 [tex]\frac{1}{5}ths[/tex] per pound)

Since there are 3 pounds, and , again, each pound can fill 5 bags, she will need 15 bags.

Another way too look at it is to ask how many 1/5ths are in 3 pounds. To find this answer mathematically:

3 ÷ 1/5 = 15 because when we divide by a fraction, we need to flip it and then multiply (so 3 ÷ 1/5 is actually 3×5)

Inequalities are expression not separated by an equality sign, They can be used to solve real world problem as well.

The inequality signs are <, >, ≤ and ≥.

≥can be termed as greater than or equal to (This means at least)

≤can be termed as less than or equal to (This means at most)

Given the inequality expression 6g - 10≥ 35. According to Scotts' response as shown;

"Rudolph has at most $35 to spend at the carnival on Saturday. He spent $10 on lunch and ride tickets are $6 per booklet. What is the maximum number of booklet he can buy?"

This is wrong since $35 was the least amount Rudolph has not the maximum amount. The correct response should therefore be:

"Rudolph has at leasts $35 to spend at the carnival on Saturday. He spent $10 on lunch and ride tickets are $6 per booklet. What is the minimum number of booklet he can buy?"

Answer:

14/25

Step-by-step explanation:

The probability that the sum of the number digits is odd is 13/ 25.

Probability is the possibility of the outcome of any random event.

We have,

Set A = 10, 17, 20, 23, 24, 28, 32, 39, 42, 45, 46, 52, 55, 58, 61, 65, 66, 72, 75, 78, 79, 85, 94, 97, 98

We have to see the number whose sum is odd.

10 = 1 + 0 = 1 (odd)

17 = 1 + 7 = 8 (even)

20 = 2 + 0 = 2 (even)

23 = 2 + 3 = 5 (odd)

24 = 2 + 4 = 6 (even)

28 = 2 + 8 = 10 (even)

32 = 3 + 2 = 5 (odd)

39 = 3 + 9 = 12 (even)

42 = 4 + 2 = 6 (even)

45 = 4 + 5 = 9 (odd)

46 = 4 + 6 = 10 (even)

52 = 5 + 2 = 7 (odd)

55 = 5 + 5 = 10 (even)

58 = 5 + 8 = 13 (odd)

61 = 6 + 1 = 7 (odd)

65 = 6 + 5 = 11 ( odd)

66 = 6 + 6 = 12 (even)

72 = 7 + 2 = 9 (odd)

75 = 7 + 5 = 12 (even)

78 = 7 + 8 = 15 (odd)

79 = 7 + 9 = 16 (even)

85 = 8 + 5 = 13 (odd)

94 = 9 + 4 = 13 (odd)

97 = 9 + 7 = 16 (even)

98 = 9 + 8 = 17 (odd)

We see that there are 13  numbers whose sum is odd.

The probability that the sum of the number digits is odd:

= 13 / 25

Thus the probability that the sum of the number digits is odd is 13/ 25.

Answer:

c. dP/dt = (1/5)P

Step-by-step explanation:

Given that the rate of change of population with respect to time dP/dt is directly proportional to the population, P, we have

dP/dt ∝ P

dP/dt = kP

Given that dP/dt = 2 million insects per day and P = 10 million insects after 5 days, So,

2 = k × 10

k = 2/10

k = 1/5

So, dP/dt = kP

dP/dt = (1/5)P

The option C is correct

The rate of change of a function with respect to the given variable.

The rate of change of population with respect to time is directly proportional to the population P. We have

[tex]\dfrac{\mathrm{d} P}{\mathrm{d} t} \propto P\\\\\dfrac{\mathrm{d} P}{\mathrm{d} t} = kP[/tex]

[tex]\dfrac{\mathrm{d} P}{\mathrm{d} t}[/tex] is 2 million insects per day and P = 10 million insects after 5 days. So

[tex]\begin{aligned} \dfrac{\mathrm{d} P}{\mathrm{d} t} &= kP\\2 &= 10k\\k &= \dfrac{1}{5} \\\end{aligned}[/tex]

Then

[tex]\dfrac{\mathrm{d} P}{\mathrm{d} t} = kP\\\\ \dfrac{\mathrm{d} P}{\mathrm{d} t} = \dfrac{1}{5} P[/tex]

Thus, option C is correct.

y = - x^2 + 4

which agrees with answer B

Step-by-step explanation:

Notice the graph is that of a quadratic function centered on the y-axis, with negative leading coefficient (branches of the parabola pointing down), and with vertex on the y-axis at the point (0, 4).

Therefore its equation is best represented by:

y = - x^2 + 4

which also crosses the x axis at the points x = -2 and x= 2, in agreement with the graph.

Step-by-step explanation:

Using the z-distribution, as we are working with a proportion, it is found that the 95% confidence interval for the difference of the proportions is (-0.052, -0.0038).

For each sample, the mean and the standard error are given by:

[tex]p_C = 0.0256, s_C = \sqrt{\frac{0.0256(0.9744)}{586}} = 0.0065[/tex]

[tex]p_H = 0.0535, s_H = \sqrt{\frac{0.0535(0.9465)}{467}} = 0.0104[/tex]

Hence, for the distribution of differences, the mean and the standard error are given by:

[tex]p = p_C - p_H = 0.0256 - 0.0535 = -0.0279[/tex]

[tex]s = \sqrt{s_C^2 + s_H^2} = \sqrt{0.0065^2 + 0.0104^2} = 0.0123[/tex]

It is given by:

[tex]p \pm zs[/tex]

In which z is the critical value.

95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].

Then, the bounds of the interval are given as follows:

[tex]p - zs = -0.0279 - 1.96(0.0123) = -0.052[/tex]

[tex]p + zs = -0.0279 + 1.96(0.0123) = -0.0038[/tex]

The 95% confidence interval for the difference of the proportions is (-0.052, -0.0038).
