Answer:

The missing value of x is 3

Step-by-step explanation:

Given Table:

 x     y

3      10

__    20

The relation of x and y (x,y) is not a function.

Relation is function if it is one-to-one.

One-to-one means to different value of x to get different value of y.

If function is not a function then one value of x to get two different value of y.

For first value of x=3, y=10

For which value of x= ? , y=20

x must be 3

x=3 to get y=20

The missing value of x is 3 because same of x we get two different value of y.

Answer:

v=20

you set IH and FG equal to each other and solve

16x

Step-by-step explanation:

6 increased by 2 --> 6+2

difference of 4 and 2 --> 4-2

first part times the second part --> 6 + 2 (4-2)

times a number --> • x

put it all together --> (6+2)(4-2) • x or 16x

Answer:

C

Step-by-step explanation:

Given :

Two similar triangles ΔABC and ΔSTU .

To Find :

The value of x.

Solution :

Since, ΔABC and ΔSTU are similar, so ratio of their sides are equal.

[tex]\dfrac{AB}{AC} = \dfrac{SU}{ST}\\\\\dfrac{x}{21}=\dfrac{13}{5}\\\\x = \dfrac{21\times 13}{5}\\\\x = 54.6[/tex]

Therefore, value of x is 54.6 .

Answer:

Answer:

what is the n?

Step-by-step explanation:

Answer: 63 ft

Step-by-step explanation:

We can think of the shadow and height of objects as the catheti of a triangle rectangle.

We also know the relationship:

Tan(θ) = (opposite cathetus)/(adjacent cathetus)

if we define:

Tan(θ) = k (a real number, such that will be the same number for every object, because it depends on the angle θ that will depend on the position of the sun)

opposite cathetis = heigt.

adjacent cathetus = length of the shadow.

Then we have:

k = height/length of the shadow.

For the mailbox, we know that the height is (4 + 1/2) ft and the shadow is 6ft long, then we have the equation:

k = (4 + 1/2)ft/6ft = 0.75

Then for the ferris wheel we know:

shadow length = 84ft

we can write the same equation as above:

k = 0.75 = height/84ft

0.75*84ft = height = 63ft

The ferris wheel is 63 ft high.

Answer:

63 feet

Answer:

a) 6 cups

Step-by-step explanation:

Use a ratio equation to solve:

3/2 = 9/x

Cross multiply to get:

3x = 18

Solve for x:

x = 6

Answer: a) 6 cups

Step-by-step explanation: The 3 cups to get to 9, is really double the amount, so if you double 3 then you double 2 and get 6. 3*2=6

Step-by-step explanation:

The missing histogram file is attached in the image below.

From the graph, deduce that:

the servings of fruits and vegetable                     number of students

0                                                                             1

1                                                                             4

2                                                                             5

3                                                                             10

Answer:

31.92% probability that 18 randomly selected bulbs would have an average life of no more than 260 days

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.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this question, we have that:

[tex]\mu = 270, \sigma = 90, n = 18, s = \frac{90}{\sqrt{18}} = 21.2[/tex]

What is the probability that 18 randomly selected bulbs would have an average life of no more than 260 days?

This is the pvalue of Z when [tex]X = 260[/tex]. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{260 - 270}{21.2}[/tex]

[tex]Z = -0.47[/tex]

[tex]Z = -0.47[/tex] has a pvalue of 0.3192.

31.92% probability that 18 randomly selected bulbs would have an average life of no more than 260 days

Answer:

the  speed of light in miles per year is 5.88 × 10^12 mi / year

Step-by-step explanation:

The computation of the speed of light in miles per year is shown below;

As we know that

1 m/sec = 1 ÷ 1609  mi/sec

3 ×10^8 m/sec = (3 × 10^8) ÷ (1609)

= (3 × 10^8 × 60 × 60 × 24 × 365) ÷ (1609)

= 5.88 × 10^12 mi / year

Hence, the  speed of light in miles per year is 5.88 × 10^12 mi / year

Answer:

[tex]\huge\boxed{576 \ \text{calories}}[/tex]

Step-by-step explanation:

In order to find the number of calories that an [tex]m[/tex] kg animal weighs, we can substitute what we need inside the formula given, [tex]72m^{\frac{3}{4}}[/tex]. Since we want to find how much a 16 kg dog needs to eat, we substitute 16 in as m.

[tex]72\cdot 16^{\frac{3}{4}}[/tex]

BPEMDAS tells us that the order of solving equations is

Brackets

Parantheses

Exponents

Multiplication/Division

Addition/Subtraction

Looking at this order, we need to do [tex]16^{\frac{3}{4}}[/tex], then multiply by 72.

When we have a number to a fraction power, we need to note that

Therefore, our expression will be [tex]\sqrt[4]{16^3}[/tex].

Now that we have this much, we need to multiply it by 72 as our formula read [tex]72m^{\frac{3}{4}}[/tex].

Therefore, an animal weighing 16 kg needs to consume 576 calories.

Hope this helped!
