Answer:

1.25 cups

Step-by-step explanation:

Since you have 5 5/8 cups = 4 1/2 water bottles

you can make it

5.625  cups = 4.5 water bottles

Then, all you have to do is divide both sides of this equation by 4.5, so

5.625 / 4.5 = 1 water bottle

1.25 cups = 1 water bottle

Answer:

4%

Step-by-step explanation:

Given data

principal= $1,700

time= 16 years

final amount=  $3,100

Applying the compound interest formula we have

r = (A/P)^1/t - 1

substitute

r=3100/1700^1/16-1

r=1.82^0.0625-1

r=1.038-1

r=0.038

Hence the rate is 0.038*100

=3.8

=4%

Answer: 3.8%

Answer:

[tex]r < 11[/tex]

Step-by-step explanation:

Given

Represent Ruth with r and Scoonsie with s

[tex]s = 11kg[/tex]

Required

Represent Ruth's weight as an inequality

From the question, Ruth weighs lesser than Scoonsie. This is represented as:

[tex]Ruth < Scoonsie[/tex]

For proper representation, it is:

[tex]r < s[/tex]

Substitute 11 for s

[tex]r < 11[/tex]

The above inequality represents Ruth's weight

Answer:

-27/8

Step-by-step explanation:

Dividing fractions is the same as multipling the first fraction by the reciprocal of the second fraction (the numerator and denomiator are flipped).

= -3/4 x 9/2

= -27/8

You can simplify this if you want so it's not a mixed fraction

= -3 3/8

[tex]\large\boxed{A = 32.5cm^{2}}[/tex]

We can use the following area to solve for the area of the trapezoid pictured:

[tex]A = \frac{1}{2}(b_{1} + b_{2})h[/tex]

Where:

h = height

b1 = bottom base

b2 = top base

Plug in the given values:

[tex]A = \frac{1}{2}(9 + 4)(5)[/tex]

Simplify:

[tex]A = \frac{1}{2}(65)\\\\A = 32.5 cm^{2}[/tex]

Answer:

The answer is "(0.73,0.87)".

Step-by-step explanation:

Given:

number of girls[tex]= 64[/tex]

number of boys[tex]= 16[/tex]

Total number of children[tex]= 64+16= 80[/tex]

So,[tex]n=80[/tex]

Calculating the value of the proportion which is given by girls:

[tex]\hat{p}= \frac{\text{number of girls}}{\text{total number of childrens}}[/tex]

  [tex]=\frac{64}{80}\\\\=\frac{8}{10}\\\\= 0.8[/tex]

Therefore the confidence interval is:  

[tex]\to \hat{p}\pm z_{(1-\frac{\alpha }{2})}\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\\\\\to 0.8 \pm 1.75\sqrt{\frac{0.8(1-0.8)}{80}}\\\\\to 0.8 \pm 1.75 \sqrt{\frac{0.8(0.2)}{80}}\\\\\to 0.8 \pm 1.75 \sqrt{\frac{0.16}{80}}\\\\\to 0.8 \pm 1.75 \sqrt{0.002}\\\\\to 0.8 \pm 1.75 (0.04)\\\\\to 0.8 \pm 0.07\\\\\to (0.73,0.87)[/tex]

[tex]\therefore \\\\\text{The lower confidence limit} = 0.73\\\\\text{The upper confidence limit} = 0.87\\[/tex]

Answer: 8 months.

Step-by-step explanation: Assuming his budget for the gym membership is $360, by dividing 360 (His budget) by the monthly cost of 45, it should leave a quotient of 8. Thus meaning he can pay for 8 months worth of gym membership.

Answer:

8 mounths

Step-by-step explanation:

Since he has $360 saved and he has to pay $45 for each month that means that in order to find out for how many months Tom can go to the jym we just have to divide 260 by 45 and so be get...

360 / 45 = 8

Step-by-step explanation:

Answer:

The probability cannot be determined.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question:

We have a sample of size less than 30, and since the distribution is not normal, the central limit theorem cannot be used, and the probability cannot be determined.

Answer:

The N is 1

Step-by-step explanation:

The computation of N is given below:

Given that there is a 1,000 cm string

That cut into the ratio of 1:N:2

So if we considered the N be 1

1,000 = 1:1:2

So it would be 250 + 250 + 500 = 1000

Hence, the N be 1

So the same is relevant

Using the ratio principle, the value of N in the expression would be 2.

Given that, the length of the string = 1000 cm :

Ratio = 1 : N : 2

Since none of the value of the ratios are given, then N could be a value such as 2 ;

If N = 2 ;

(1000 / 5) × 1 = 200 cm

(1000 / 5) × 2 = 400 cm

(1000 / 5) × 2 = 400 cm

Hence, the value of N in the expression is 2.

Answer: C. g^(-1) (x)= 1/(x+ 2)

Step-by-step explanation:

y=1/x-2

x=1/y-2

1/y-2=x

1/y=x+2

1=(x+2)y

1=xy+2y

xy+2y=1

(x+2)y=1

y=1/(x+2)

answer: g^(-1) (x)= 1/(x+ 2)
