Triangles cannot have two 90 degrees because that would add up to 180 and triangles need 3 angles to add to 180

You can't have an obtuse angle and a right angle. say the obtuse angle was 110, and a right angle is 90. 110 + 90 is more than 180.

Two obtuse angles would be more than 180.

This leaves us with B being correct, because you can have an obtuse angle and an acute angle, and it can be less than 180 degrees.

The shape of the distribution for the given set of data is positively skewed.

A positively skewed distribution is characterized by a long tail on the right side of the distribution. In this case, the mode (most frequently occurring value) is 5, while the values 1, 2, 3, 4, and 6 have fewer occurrences. This creates a longer tail on the right side of the distribution, indicating a positive skew.

The data is skewed towards the higher end, or right-skewed with a higher frequency towards the higher scores.. The frequency decreases as we move towards the lower scores.

In its new location, the entry will display as =M$7.

When a formula containing the entry =J$7 is copied to a cell three columns to the right and four rows down, certain adjustments occur. The entry has a dollar sign ($) before the row number, which means the row reference remains fixed during copying, while the column reference adjusts relatively.

For the row adjustment, copying four rows down from J$7 results in the new row reference being 7 + 4 = 11.

For the column adjustment, copying three columns to the right from J$7 means that the column reference moves three letters to the right, resulting in the new column reference being M.

Combining the adjusted row and column references, we get =M$7 as the entry displayed in its new location.

54/9 = 6

hence, 9 * 6 = 54

x * 6 = 8

x = 8/6

x = 4/3

Answer:

it would cost $34.50 to purchase 7.5 lbs of walnuts.

Answer:

$34.50

Step-by-step explanation:

First find out how much 1/4 of a lb will cost.

3.45/3= 1.15

This is the cost for only 1/4 a lbs of chopped walnuts. Take this number and multiply it by 4 to find how much it would cost for 1 whole pound of walnuts.

1.15x4= 4.60

It costs $4.60 for a whole pound of walnuts. If you are trying to find how much it costs for 7.5 lbs, then multiply 4.60 by 7.5.

4.60x7.5= 34.5

For 7.5 lbs of walnuts will cost $34.50

There is no base number that satisfies the given equations, because none of the equations are correct.

The correct equations are:

(a) 12 × 4 = 48(b) 24 × 17 = 408

3 is not equal to 3.6(e) (x^2 - 13x + 32) = (x - 5)(x - 8)

Therefore, x = 5 or x = 8.

Answer:

- 1 \(\frac{1}{3}\)

Step-by-step explanation:

-3.75 can be written as a fraction as -3 \(\frac{75}{100}\) o r-3 \(\frac{3}{4}\)  if I divide the numerator and the denominator by 25.

\(\frac{2}{5}\) (-3 \(\frac{3}{4}\))

We can change -3 \(\frac{3}{4}\) into an improper fraction.  We can do that a few ways but I am going to the it the way that is most intuitive to me.

another name for 1 is \(\frac{4}{4}\) because 4 ÷ 4 = 1.  I am going to use that knowledge to convert -3 \(\frac{3}{4}\) into a mixed number.

-( \(\frac{4}{4}\) + \(\frac{4}{4}\) + \(\frac{4}{4}\) + \(\frac{3}{4}\)) =  - \(\frac{15}{4}\)  The negative sign can go in the numerator, denominator or in front to the fraction to show that the number is negative.

\(\frac{2}{5}\) x  -\(\frac{15}{4}\)  = - \(\frac{30}{20}\)  Divide the numerator and the denominator by 10

= \(\frac{3}{2}\)

Which means the same thing as -( \(\frac{2}{2}\) + \(\frac{1}{3}\) ) which means the same thing as -(1 + \(\frac{1}{3}\) +or -  1 \(\frac{1}{3}\)

y = -1/3x + 1

y = -2x - 3

We can compare the equations to the graphs and see which graph represents the intersection point of the two equations.

The first equation, y = -1/3x + 1, has a negative slope (-1/3) and a y-intercept of 1.

The second equation, y = -2x - 3, also has a negative slope (-2) and a y-intercept of -3.

Based on the slopes and y-intercepts, we can identify the correct graph by finding the point where the two lines intersect.

Unfortunately, since the graphs are not provided, I am unable to determine which specific graph shows the solution to the system of linear equations. I recommend referring to the graph representation of the equations and identifying the intersection point to determine the correct graph.

Answer:From the given information, we know that after sailing for 2 hours, Alvin and his friends are 10 miles from shore. This can be written as y = 10 when x = 2.

Since there is a proportional relationship between x and y, we can write an equation using this information: y = kx, where k is the proportionality constant.

Substituting the known values, we get: 10 = k * 2

Solving for k, we get: k = 10/2 = 5

So, the equation relating x and y is: y = 5x

To find their distance from shore after sailing for 3 hours, we can plug in x = 3 into the equation:

y = 5x

y = 5 * 3

y = 15

So, after sailing for 3 hours, Alvin and his friends are 15 miles from shore.

It will cost $300 to carpet a rectangular floor that is 10 feet by 12 feet.

The cost of carpeting a rectangular floor, we need to determine the area of the floor and multiply it by the cost per square foot.

The area of a rectangle is found by multiplying its length by its width. In this case, the length is 10 feet and the width is 12 feet.

Area = Length × Width Area

Area = 10 feet × 12 feet Area

Area = 120 square feet

Now, we can calculate the cost of carpeting by multiplying the area by the cost per square foot

Cost = Area × Cost per square foot Cost

Cost = 120 square feet × $2.50 per square foot

Cost = $300

Therefore, it will cost $300 to carpet a rectangular floor that is 10 feet by 12 feet.

The difference between the amounts of interest Marcus and Gianna paid for their car loan is $50

The formula for calculating the amount on simple interest is given as:

A = P + I

I = PRT
A = PRT + P

Given the following paramteers

A = 10000(0.047)(5) + 100000

A = 2350 + 10000
A = 12350

For Gianna

A = 10000(0.045)(5) + 100000

A = 2250 + 10000

Answer:

Green Pens : 21

Step-by-step explanation:

Let the number of
green pens = x

Three more blue pens than green pens translates to
=> number of blue pens = number of green pens + 3
=> blue pens  = x + 3

Total number of pens = blues + green = x + 3 + x = 2x + 3

Probability of taking 2 green pens:
The first time a green pen is taken out, the probability
P( 1s green pen) = Number of green pens/Total number of pens

= \(\dfrac{x}{2x + 3}\)

After the first green pen is removed, the number of green pens will be one less and so will the total number of pens

Number of green pens = x - 1
Total number of pens = 2x + 3 - 1 = 2x + 2

P(second green pen | first green pen)

\(=\dfrac{x-1}{2x + 2}\)

P(2 green pens) = P(first green pen) x P(second green pen)
\(= \dfrac{x}{2x + 3} \times \dfrac{x-1}{2x + 2}\\\\=\dfrac{x(x -1)}{(2x +3)(2x+2)}\)          [1]

Probability of 2 blue pens

P( 1st blue pen) = number of blue pens/total number of pens
\(=\dfrac{x + 3}{2x + 3}\)

P(second blue pen = (number of pens remaining if first was blue) ÷ total number of pens - 1

If the first pen taken was blue then there will be 2x + 3 - 1 blue pens out of a total of 2x + 3 - 1 pens

P(2nd blue pen | first blue pen)

\(=\dfrac{x + 2}{2x + 2}\)

\(\text{P(2 blue pens)} =\dfrac{x + 3}{2x + 3} \times \dfrac{x + 2}{2x + 2}\)\(=\dfrac{(x + 3)(x+2)}{(2x + 3)({2x + 2})}\)  [2]

The probability of either 2 green pens or 2 blue pens is the sum of the two probability expressions [1] and [2]

\(= \dfrac{x(x -1)}{(2x +3)(2x+2)} + \dfrac{(x + 3)(x+2)}{(2x + 3)({2x + 2})}\)

\(= \dfrac{x(x - 1)+ (x + 3) (x +2)}{(2x + 3)(2x + 2)}\\\\\\= \dfrac{2x^2+4x+6}{(2x + 3)(2x + 2)}\\\\\\\\\)

Numerator: factor out 2 to get 2(x² + 2x + 3)

denominator = 4x²+10x+6 = 2 (2x² + 5x + 3)

2 of numerator and 2 of denominator cancel out to give the final expression:

\(\dfrac{x^2\:+\:2x\:+\:3}{2x^2+\:5x\:+\:3}\)

But we are given that the probability of picking 2 pens of the same color = 27/55

This will give us:
\(\dfrac{x^2\:+\:2x\:+\:3}{2x^2+\:5x\:+\:3} = \dfrac{27}{55}\)

Cross-multiplying we get

\(55\left(x^2+\:2x\:+\:3\right)=27\left(2x^2+\:5x\:+\:3\right)\)

=> \(55x^2+110x+165 = 54x^2+135x+81\)

Grouping like terms and simplifying gives
\(x^2-25x+84=0\)

This is a quadratic equation which can be solved using a scientific calculator (as I did)

The solution set is

x = 21, x = 4

Remember x = number of green pens. We can ignore x = 4 because the total number of pens given by the expression 2x + 3 will be less than 12 and we are told there are more than 12 pens total

So the solution is x = 21 (number of green pens)
Number of blue pens = x + 3 = 21 + 3 = 24
