Answer:

[tex]New\ Position = -415m[/tex]

Step-by-step explanation:

Given

[tex]Position= -300m[/tex]

[tex]Descend = 115m[/tex]

Required

Determine the new position

It descends means that it moved in the downward position.

So, the new position is:

[tex]New\ Position = Position - Descend[/tex]

[tex]New\ Position = -300m - 115m[/tex]

[tex]New\ Position = -415m[/tex]

Hence, the new position f the submarin is -415m

Answer:

0.6% of the people had a mild allergic reaction.

Step-by-step explanation:

Given that:

Number of people who tried hair care products = 6000

Number of people who had reaction = 36

Percent of people = [tex]\frac{Number\ of\ people\ with\ reactions}{Total\ number}*100[/tex]

Percent of people = [tex]\frac{36}{6000}*100[/tex]

Percent of people = 0.6%

Hence,

0.6% of the people had a mild allergic reaction.

Answer:

2.23%

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = < 64 inches

μ is the population mean = 69

σ is the population standard deviation = 2.5

Since: Participants must be less than 64 inches tall.

For x < 64 inches

z = 64 - 69/2.5

z = -2

Probability value from Z-Table:

P(x<64) = 0.02275

Converting to percentage

= 0.02275 × 100

= 2.275%

Approximately = 2.23%

Because participants must be less than 64 inches tall to participate in this limbo contest, the percent of adult American males thag could enter this contest is 2.23%

Answer:

£44

Step-by-step explanation:

We have been given the ratio 1 : 3 , where 1 is stephens value and 3 is bridgets value.

We have told that stephen gets £11.

The relationship between stephens 'value' of 1 and the amount of money that he actually gets (11) is x11.

Therefore we must also x11 to Bridgets value.

11 x 3 = £33

Now, we add the two answers to find how much they won in total.

£33 + £11 = £44

hope this helps :)

Answer:

The minimum of a - b is 41.325

Step-by-step explanation:

Let us solve the question using upper and lower boundaries

∵ a = 49.0 rounded to 1 decimal place

∵ 1 decimal place means 0.1

→ Divide 0.1 by 2

∵ 0.1 ÷ 2 = 0.05

→ Add 0.05 to the rounded number to get the upper boundary

∵ 49.0 + 0.05 = 49.05

∴ The upper boundary = 49.05

→ Subtract 0.05 from the rounded number to get the lower boundary

∵ 49.0 - 0.05 = 48.95

∴ The lower boundary = 48.95

∴ The range of a is 48.95 ≤ a < 49.05

∵ b = 7.62 rounded to 2 decimal places

∵ 2 decimal place means 0.10

→ Divide 0.01 by 2

∵ 0.01 ÷ 2 = 0.005

→ Add 0.005 to the rounded number to get the upper boundary

∵ 7.62 + 0.005 = 7.625

∴ The upper boundary = 7.625

→ Subtract 0.005 from the rounded number to get the lower boundary

∵ 7.62 - 0.005 = 7.615

∴ The lower boundary = 7.615

∴ The range of b is 7.615 ≤ b < 7.625

To find the minimum value of a - b, use the smallest value of a and the greatest value of b

∵ The minimum of a - b = lower boundary of a - upper boundary of b

∴ The minimum of a - b = 48.95 - 7.625

∴ The minimum of a - b = 41.325

∴ The minimum of a - b is 41.325

Answer:

Equation: 420 = 7/6b, Original balance: $360, Interest earned: $60.

Step-by-step explanation:

Since 420 is 7/6 of the original balance, and of means mulitply, we can make this into an equation, the equation is 420 = 7/6b. Let's solve the equation for b. Multiply both sides by 6 to get 2520 = 7b. Now, let's divide both sides by 7. This gets us 360 = b. This means the original balance was $360. Now, let's find the interest earned. We know that 420 is 7/6 of 360, so that means the interest earned was 1/6 of the original balance. Let's make sure, first. 360/6 is 60, and 360+60 is 420, so everything checks out.

Answer:

0.375

Step-by-step explanation:

Given that there is 50% chance of having a boy in a single birth.

Let it be represented by p, so

p=50%=0.5

According to Bernoulli's theorem, the probability of exactly r success in n trials is

[tex]P(r)=\binom {n}{ r} p^r(1-p)^{n-r}[/tex]

where p is the probability of success.

So, the probability of exactly 2 boys (success) in a total of 3 birth (trials) is

[tex]P(r=2)=\binom {3}{ 2} p^2(1-p)^{3-2}[/tex]

As p=0.5, so

[tex]P(r=2)=\binom {3}{ 2} (0.5)^2(1-0.5)^{3-2} \\\\=\binom {3}{2} (0.5)^2(0.5)^{1} \\\\=3\times 0.5^3[/tex]

=0.375

Hence, the probability of exactly 2 boys in a total of 3 birth is 0.375.

Answer:

72 mles

Step-by-step explanation:

For better understanding, I'll make use of an attachment.

From the attachment,

O represents the start point

[tex]OB = 30[/tex] --- Jack

[tex]AB = 78[/tex] -- Distance between them

Required

Find OA; Jack's distance

To do this, we make use of Pythagoras theorem

[tex]AB^2 = OA^2 + OB^2[/tex]

This gives:

[tex]78^2 = OA^2 + 30^2[/tex]

[tex]6084 = OA^2 + 900[/tex]

Subtract 900 from both sides

[tex]OA^2= 6084 - 900[/tex]

[tex]OA^2= 5184[/tex]

Take square roots

[tex]OA = \sqrt{5184}[/tex]

[tex]OA = 72[/tex]
