Answer:

Distance between coordinates is given as √(x1-x2)²+(y1-y2)², where x and y are the coordinates of the points.

Length of ST = √(-2-3)²+(4-9)²

= √(-5)²+(-5)²

= √25+25

= √50

The cost for making the container is  $28. 27

From the information given, we have that;

We also have the following deductions;

The properties of a square prism are;

The cost for aluminum = 10($1.57)

expand the bracket

The cost for aluminum = $10. 57

The cost for steel = 6($2.95)

The cost for steel = $17. 7

Total cost for the container = $10. 57 +  $17. 7

Total cost for the container = $28. 27

Hence, the cost is $28. 27

Reason:

The cube root undoes the cubing operation.

It's similar to how the square root undoes squaring.

Your calculator should have a cube root button, or an nth root button. If not, then you can type in 1331^(1/3)

The exponent of 1/3 is the same as a cube root.

The result of 1331^(1/3) is 11

11^3 = 11*11*11 = 1331

Interpretation: You have a box that is 11 cm by 11 cm by 11 cm. The volume is 11^3 = 1331 cubic cm.

As you can see, the cube root is useful if you know the volume and want to work backwards to determine the side length of the cube.

the cube root of 1331 = ∛(11 × 11 × 11) = 11.

The square root of 1331 is 36.48287.

Answer:

-6

Step-by-step explanation:

First using the point slope form to find the equation for the line.

y -y1 = m (x-x1)

you plug in the given x and y values (7, 8)

which gives you y - 8 = 7(x-7)

isolate for y: y=8+7(x-7)

Now plug in 5 into the equation you got to solve for f

y = 8 + 7 (5-7)

y = 8 + 7(-2)

y = 8 - 14

y = -6

If one student is picked randomly in the class, the probability of a student being long haired female is 9 out over 20 students.

Probability is defined as the ratio of outcomes that are more likely to occur than all other outcomes of an event. For an experiment with 'n' number of outcomes, the number of favorable outcomes can be denoted by the symbol x. To calculate the likelihood of an event, use the following equation.

Probability (event) = favourable outcomes/ total outcomes (x/n)

Let the number of students in a particular college be 100

Then, if 60% are female that means 60 students are girls (60/100 × 100)

Now, it is said that 75% of females have long hair, that means

75% of 60 girls have long hairs, if we calculate then we find that

⇒ 75/100 × 60

⇒ 3/4 × 60

⇒ 3 × 15

⇒ 45 girls are long haired

Now the probability of a female being longed hair is

⇒ favourable outcomes/ total outcomes

⇒ 45/100

⇒ 9/20

Thus, the probability of a student being long haired female is 9 out over 20 students.

Assume that births are randomly selected and of the 50 births, 49 are girls. use subjective judgment to describe the number of girls as significantly high, significantly low, or neither significantly low nor significantly high.

Based on the information provided, the number of girls in the births cannot be categorized as significantly high, significantly low, or neither significantly low nor significantly high, solely through subjective judgment.

The description of "significantly high" or "significantly low" typically requires statistical analysis and comparison to a reference point or expected value. Without knowing the total number of births or having a reference point for the expected proportion of girls in the births, it is not possible to determine whether the number of girls is significantly high or low.

The term "significantly" in statistics usually involves assessing whether an observed value deviates from an expected value by a statistically significant margin.

Subjective judgment alone cannot accurately assess whether the number of girls in the births is significantly high or low. To determine significance, a statistical analysis would involve calculations such as calculating the expected proportion of girls, performing hypothesis testing, and assessing the p-value to make an informed judgment.

Without these quantitative measures, it is not possible to make an accurate subjective determination of the significance of the number of girls in the births.

The volume of cylinder is 1152π cm³.

What is volume?

Volume is a measurement of three-dimensional space that is filled. It is frequently mathematically quantified using SI-derived units (such as the cubic metre and litre) or other imperial units (such as the gallon, quart, cubic inch). Volume is connected to the notion of length (cubed). The volume of a container is commonly believed to be its capacity; that is, the amount of fluid (gas or liquid) that the container can hold, rather than the amount of space that the container occupies. Volume was measured in ancient times using similar-shaped natural containers and, subsequently, standardized vessels. The volume of several simple three-dimensional forms may be easily computed using mathematical methods.

Radius of a sphere = 6 cm

Volume of a sphere = (4/3)πr³ = (4/3).π.6³ = 288π cm³

Therefore, volume of cylinder = 288π x 4 = 1152π cm³

By cross multiplying, you can simplify the equation and solve for the unknown variable.

Cross multiplication is a technique used when solving equations involving fractions. It is typically used when you have a proportion or an equation with fractions, and you want to eliminate the denominators and solve for the unknown variable.

Cross multiplication involves multiplying the numerator of one fraction by the denominator of the other fraction and vice versa. This technique is useful for simplifying equations and solving for the unknown variable.

You should cross multiply with fractions when you have an equation in the form:

a/b = c/d

To cross multiply, you would multiply ad (product of the numerators) and bc (product of the denominators) and set them equal:

Step-by-step explanation. hope it helps

Answer:

x = 5

Step-by-step explanation:

8x + 7 = 2x + 37  Subtract 2x from both sides of the equation

6x + 7 = 37  Subtract 7 from both sides

6x = 30  Divide both sides by 6

x = 5

Or you could plug in 5 for x and solve.  If the equation is true, that is the answer

x= 5

8x + 7  = 2x + 37

8(5) + 7 = 2(5) + 37

40 + 7 = 10 + 37

47 = 47

If you try this with any other number, it will not equal.  Lets try x = 11

8x + 7 = 2x + 37

8(11) + 7 = 2(11) + 37

88 + 7 = 22 + 37

95 ≠ 59 so x does not equal 11

The minimum number is 9 GB to make the unlimited cheaper.

A gigabyte is a specific unit of data that's equal to about 1 billion bytes of data. The term gigabyte is typically used to describe the amount of stored data or the capacity of a storage device. For example, an HDD might offer 500 GB of raw capacity but is currently storing only 200 GB of data.

Given that,

A tablet data provider offers different plans for data usage

The plan Raul chose has a monthly fee of $29.99 per month for 5 GB of data with an additional cost of $10 for each gigabyte over 5.

Assume that he will use n gigabyte per month

The monthly fee is $29.99 for 5 GB

∵ The cost per GB after the first 5 GB is $10

∵ The number of GB whose cost is $10 is (n - 5)

∴ His monthly fees = 29.99 + 10 (n - 5) ⇒ current plan

The fees of the unlimited is $59.99 per month

∵ We need the unlimited cheaper than current plane

Let the current plan greater than the unlimited plan

∴ 29.99 + 10 (n - 5) > 59.99

Subtract both sides by 29.99

∴ 10 (n - 5) > 30

Divide both sides by 30

∴ n - 5 > 3

Add both sides by 5

∴ n > 8

Hence, The minimum number is 9 GB to make the unlimited cheaper.
