Answer:

she would walk at least those 62 miles

Step-by-step explanation:

We are told that in the 3 days of the walk to fight cancer, Mary breaks the 62 mile barrier every day, that is to say that every day she travels 62 miles or more.

You ask us how much she walks in a single day, considering what the statement that goes at least 62 miles each day says, she would walk at least those 62 miles on a normal day.

Answer:

The answer 28.27 *2 = 56.54

Step-by-step explanation:

A= πr^2

The area of Maria's circle, which is double the area of circle G is: 56.52 sq. cm.

Given:

Radius (r) of circle G = 3 units

Area of circle G = π(3²) = 28.26 sq. units.

Area of Maria's circle = 2(area of circle G)

Therefore:

Area of Maria's circle = 2(28.26)

Area of Maria's circle = 56.52 sq. cm.

Answer:

The balance of the account is $64,190.

Step-by-step explanation:

The amount of money after t years of continous compounding is given by the following equation:

[tex]P(t) = P(0)e^{rt}[/tex]

In which P(0) is the initial deposit and r is the interest rate, as a decimal.

$60,000 deposited for 6 years at 1.125% interest compounded continuously.

This means that [tex]P = 60000, r = 0.01125, t = 6[/tex]

So

[tex]P(6) = 60000e^{0.01125*6} = 64190[/tex]

The balance of the account is $64,190.

Answer:

12

Step-by-step explanation:

Seema’s little sister is 2 years more than ¼ of Seema’s age, so you should subtract 2 from 5 to find ¼ of Seema’s age. If 3 is ¼ of Seema’s age, all you do is multiply it by 4 to get the original number. 3x4 is 12, so the final answer is that Seema is 12.

Answer:

x = -1

Step-by-step explanation:

15+3x=3(2−2x)

Distribute

15+3x = 6 -6x

Add 6x to each side

15+3x+6x = 6-6x+6x

15+9x = 6

Subtract 15 from each side

15-15+9x = 6-15

9x = -9

Divide by 9

9x/9 = -9/9

x = -1

Answer:

a)  (0.124, 0.435)

b) I am 95% confident that the proportion difference is between 0.124 and 0.435

Step-by-step explanation:

Given that:

For male students: number of male students ([tex]n_m[/tex]) = 69, number who liked the new method (x) = 38

For female students: number of female students ([tex]n_f[/tex]) = 73, number who liked the new method (x) = 20

a) The probability that a male student like the new method ([tex]P_1[/tex]) is given as:

[tex]P_1=\frac{38}{69} =0.55[/tex]

The probability that a female student like the new method ([tex]P_2[/tex]) is given as:

[tex]P_2=\frac{20}{73} =0.27[/tex]

c = 95%, α = 1 -c = 0.05

[tex]z_{\frac{\alpha }{2} }=1.96[/tex]

the difference between the proportions of male and female students who like the new method better = [tex]P_1-P_2[/tex] ± [tex]z_{\frac{\alpha }{2} }\sqrt{\frac{P_1(1-P_1)}{n_m} +\frac{P_2(1-P_2)}{n_f}}[/tex] =  [tex]0.55-0.27[/tex] ± [tex]1.96\sqrt{\frac{0.55(1-0.55)}{69} +\frac{0.27(1-0.27)}{73}}[/tex]  = (0.124, 0.435)

Step-by-step explanation:

1 fluid ounce = 6 teaspoons

Answer:

2-1=1 so A. is 100% more than B because A is 2 times bigger than B.

A. is the answer 2:1

Hope this helps

Step-by-step explanation:

The option that shows the ration A: B is Option C - 1:2. See the rationale below.

If A is 100% more than B, it means that A is equal to B plus 100% of B. In other words, A is twice the value of B.

Therefore, the ratio of A to B is 1:2, indicating that A is twice as much as B.

Recall that a ratio is a quantitative relationship between two or more quantities, indicating how many times one quantity is contained or repeated in relation to another quantity.

It is expressed as a fraction or with a colon (:), representing the relative comparison of the quantities.

The number of cups of water the hiker should carry is 12 cups.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, a hiker is told to carry 2 cups of water for every 10 minutes spent walking.

Now, number of cups of water carry for 1 minute

= 2/10

= 0.2 cups

The number of cups of water carry for 60 minutes

= 0.2×60

= 12 cups

Therefore, the number of cups of water the hiker should carry is 12 cups.

Answer:

2/45

Step-by-step explanation:

Total socks:

7 + 8 + 10 + 5 = 30

P(blue) × P(patterned)

8/30 × 5/30

4/15 × 1/6

2/45

Answer:

2/45

Step-by-step explanation:

The total number of socks is 7+8+10 +5

30

P(blue) = number of blue socks / total

           = 8/30 = 4/15

Then we replace it so we have the same number of socks

P(patterned) = number of patterned socks / total

                     = 5/30 = 1/6

P(blue, replace/patterned) = 4/15*1/6

                                             =2/45

All angles are of triangle and thus give sum of 180⁰

x + 5 + 7x - 5 + x = 180⁰

9x = 180⁰

x = 20⁰

Answer:

it's 20

Step-by-step explanation:

(X+5)° + (7x-5)° + x°= 180° { sum of the three angles of the triangle is 180°}

X+5+7x-5+X = 180

X+7x+X+5-5= 180

9x+0 = 180

9x = 180

therefore X= 180/9

Answer:

a) MA conditional with C can be interpreted as A which is known and C which is unknown match

b) 10/11

c) 2/11

Step-by-step explanation:

A={A is the guilty party}

[tex]M_A[/tex] = {A blood type matches that of the guilty party}

C = {B is the guilty party}

[tex]M_C[/tex] = {B blood type matches that of the guilty party}

a) The chance is 10% because MA conditional with C can be interpreted as A which is known and C which is unknown match

b) the probability that A is the guilty party is given by [tex]P(A/M_A)[/tex]. Using bayes theorem:

[tex]P(A/M_A)=\frac{P(M_A/A)P(A)}{P(M_A/A)P(A)+P(M_C/C)P(C)} =\frac{1*1/2}{(1*1/2)+(1/10*1/2)} =\frac{10}{11}[/tex]

c) the probability that B’s blood type matches that of the guilty party is given as [tex]P(M_C/M_A)[/tex]. Using LOTS Therefore:

[tex]P(M_C/M_A)=P(M_C/M_A,A)P(A/M_A)+P(M_C/M_A,A)P(C/M_A)=\frac{1}{10}*\frac{10}{11} +1*\frac{1}{11} =\frac{2}{11}[/tex]

75 sweets.

Step-by-step explanation:

Pip gets 7/(7+5) = 7/12 .

Let Sara get x sweets so Pip gets 7/5 x sweets.

7/5 x = x + 30

2/5 x = 30

x = 5/2 * 30 =  75.

Sara gets 75 sweets.

Answer:

Sara has £75

Step-by-step explanation:

Pip : Sara

Answer:

35 years old.

Step-by-step explanation:

To find the age of Gwen, multiply Robin's age, which is 11, by 3, which gives you 33. Then add two to 33 to get Gwen's age, which is 35 years.

Answer:

Gwen is 35 years old

Step-by-step explanation:

In order to understand the word problem better, I turned it into and equation.

Since Gwen is 2 years older than 3 times Robins age, the equation would be:

Gwens age = (3 • Robins age) + 2

G = (3 • 11) + 2

G = (33) + 2

G = 35

So Gwen is 35 years old.

a) [tex] t_{\alpha}= 1.753[/tex]

b) [tex] t_{\alpha}= -1.383[/tex]

c) [tex] t_{\alpha/2}= \pm 2.179[/tex]

Step-by-step explanation:

Part a

For this case we know that the degrees of freedom are:

[tex] df = 15[/tex]

And we want a right tailed test so then we need to find in the t distribution with degrees of freedom =15 a critical value who accumulate 0.05 of the area in the right and we got:

[tex] t_{\alpha}= 1.753[/tex]

Part b

For this case the significance is [tex]\alpha=0.1[/tex] the degrees of freedom are:

[tex] df = n-1= 10-1=9[/tex]

And since is a left tailed test the critical value for this case would be:

[tex] t_{\alpha}= -1.383[/tex]

Part c

For this case the significance is [tex]\alpha=0.05[/tex] and [tex]\alpha/2=0.025[/tex] the degrees of freedom are:

[tex] df = n-1= 13-1=12[/tex]

And since is a two tailed test the critical values for this case would be:

[tex] t_{\alpha/2}= \pm 2.179[/tex]

Answer:

C
