Drag and drop the numbers into the ordered pairs. I'm so so confused. Can somebody please please help? I put the drag and drop numbers as the second picture.

Answer:

X=4

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

We can find the length of the hypotenuse of the 45 45 90 triangle using the other triangle (which is 30 60 90)

Since the hypotenuse is 8[tex]\sqrt{2}[/tex], the short leg (hypotenuse of other triangle) will be 4[tex]\sqrt{2}[/tex]

This means the value of x must be 4

Answer:

B=264 b5/34 a576 5739 7985

Answer:

6p - 2

Step-by-step explanation:

9p - (3p + 2) = 9p - 3p - 2 = 6p - 2

The expression that  is equivalent to 9 p minus 3 p + 2 is 6p - 2

From the question, one have 9p - 3p + 2.

So, one has to combine the like terms, which means adding or subtracting the coefficients of the same variable. For the terms with 'p', one  have 9p - 3p.

Combining the coefficients, one get 9 - 3 = 6.

So, 9p - 3p is simplifies to 6p.

So, one have 6p + 2.

The expression is said to be now simplified to 6p + 2.

Answer:

nope!

Step-by-step explanation:

mean= average, total of numbers/ amount of numbers

median- if all the numbers were in a line what would be in the middle

mode-most reoccuring number- remember it cos it rhymes with most :)

hope this helps :)

can u pls give brainliest? :)

Answer:

No

Step-by-step explanation:

when you have a list of numbers:

The mean is all of the numbers added up and then divided by the number of numbers.

The median is "the middle number" So line them up in numerical order and find the middle number.

The Mode is the biggest number subtracted from the smallest number.

Answer:

0.33 hours or 20 minutes

Step-by-step explanation:

Speed is given as distance divided by time.

That is:

s = d / t

Therefore, time will be:

t = d / s

The train traveled a distance of 40 km at 120 km/h. Therefore, the time taken will be:

t = 40/120 = 0.33 hours or 20 minutes

Answer:

- The actual product is less than the estimate

- The numbers differ by less than one

Step-by-step explanation:

Given

Product of 3 and two-fifths & [tex]-3\frac{7}{8}[/tex]

Required

Compare actual result with approximated result

Calculating the actual result;

3 and two-fifths means [tex]3\frac{2}{5}[/tex]

So, the Product of 3 and two-fifths & [tex]-3\frac{7}{8}[/tex] becomes

[tex]Product = 3\frac{2}{5} * -3\frac{7}{8}[/tex]

Convert fractions to improper

[tex]Product = \frac{17}{5} * -\frac{31}{8}[/tex]

Combine fractions to form one

[tex]Product = \frac{-17 * 31}{5 * 8}[/tex]

Multiply numerators and denominator

[tex]Product = \frac{-527}{40}[/tex]

Convert fraction to decimal

[tex]Product = -13.175[/tex]

The nearest half of -13.175 is -13

Hence;

[tex]Estimate = -13[/tex]

By comparison:-

- The actual product (-13.175) is less than the estimate (-13)

- The difference between both results is less than 1;

The difference is calculated as follows

Difference = |Actual Product - Estimate|

Difference = |-13.175 - (-13)|

Difference = |-13.175 +13|

Difference = |-0.175|

Difference = 0.175

Answer:

B

The actual product is greater than the estimate. The numbers differ by less than one. took the test 2021

Answer:

The correct option is;

(B) 30

Step-by-step explanation:

The equations are;

x² - 2·m·x - 5·n = 0.............(1)

Solution = p, q

x² - 2·p·x - 5·q = 0..............(2)

Solution = m, n

For equation (1), we have;

x² - 2·m·x - 5·n = 0 = (x - p)·(x - q)

x² - 2·m·x - 5·n = x² -x·p - x·q + q·p = x² -x·(p + q) + q·p

2·m = p + q..............(3)

5·n = -q·p..............(4)

Given the similarity between equation (1) and (2), we have;

2·p = m + n..............(5)

5·q = -m·n..............(6)

Therefore;

m = (p + q)/2

n = -q·p/5

Substituting the value of m and n in equation (5) and (6), we have;

2·p = (p + q)/2  - q·p/5.............(7)

5·q = (p + q)/2·q·p/5.............(8)

Making q the subject of equation (7) gives;

[tex]q = \dfrac{-7.5 \cdot p}{p -2.5}[/tex]

Substituting the value of q above in equation (8) gives;

[tex]-\dfrac{75\cdot p}{2\cdot p-5}=-\dfrac{3\cdot p^{4}-30\cdot p^{3}}{4\cdot p^{2}-20\cdot p+25}[/tex]

By cross multiplying and collecting like terms we have;

6·p⁵ -75·p⁴-150·p³+1500·p²-1875·p = 0

Which gives

(p+0)(p-1.91)(p-2.5)(p+5)(p-13.1)

p = 1.91 or 2.5 or -5 or 13.1

q = 24.27 or undef or -5 or -9.27

m = 13.09 or undef or -5 or 1.95

n = -9.27 or undef or -5 or -24.29

Therefore, p + q + m + n = 1.91 + 24.27 + 13.09 + (-9.27) = 30

The correct option is (B) 30

Step-by-step explanation:

Assume that the two prisms have bases of equal area.

Then the volume of the rectangular prism is V = (base area)(height).

The volume of the triangular prism is V = (1/3)(base area)(height)

We could compare the two volumes by creating the ratio inequality

  (1/3) (base area)(t-height)

------------------------------------------

      (base area)(r-height)

The triangular prism will have the greater volume for (1/3)((t-height) > r-height.

Answer : The fifth term in the sequence is -2.

Step-by-step explanation :

As we are given that the expression to calculate the [tex]n^{th}[/tex] term.

The expression is as follows:

[tex]a_n=2(-1)^n[/tex]

where,

n is the number of term

Given:

n = 5

Now putting the value of n in the above expression, we get:

[tex]a_n=2(-1)^n[/tex]

[tex]a_5=2(-1)^5[/tex]

Answer:

58.43%

Step-by-step explanation:

The first thing we must do is calculate the probability of when both are equal, that is, take out two cookies of the same type, since we can calculate that they are not equal by means of their complement:

The probability that they are equal is:

P (plain, plain) = (12/20) (11/19)

= 132/380

P (chocolate, chocolate) = (5/20) (4/19)

 = 20/380

P (currant, currant) = (3/20) (2/19)

= 6/380

The final probability would be the sum of these:

P (equal) = 132/380 + 20/380 + 6/380

P (equal) = 158/380

P (equal) = 0.4157

The probability that they are different is the opposite of the probability that they are equal, that is, the complement. Therefore, the probability that they are different is:

P (different) = 1 - 0.4157

P (different) = 0.5843

In other words, the probability would be 58.43%

Answer:

B

Step-by-step explanation:

When you dilate by a factor of 0, this doesn't really make sense because the length of each side is multiplied by 0, and the shape basically doesn't exist anymore. When you multiply by a scale factor of 1, the figure does not change in size at all. When you dilate by a scale factor of 5, each side length gets 5 times larger, meaning that this is not a reduction. Hope this helps!

Step-by-step explanation:

The first term of the arithmetic sequence is  4x+3.

An ordered group of numbers with a shared difference between each successive term is known as an arithmetic sequence.

The formula to find the nth term of an arithmetic sequence is,

aₙ= a+(n-1)d

Where a is the 1st term and d is the common difference.

Let the first term of sequence is a and the common difference is d.

Given that,

The 5th term of the arithmetic sequence = 16x+11,

⇒ a+4d= 16x+11      (1)

And the 9th term of the arithmetic sequence = 28x+19,

⇒ a+8d= 28x+19    (2)

To find the first term of the sequence, multiply equation (1) with 2 and subtract equation (2) from it.

(2a+8d)-(a+8d) = (32x+22) - (28x+19)

a = 4x+3

The first term of the arithmetic sequence is  4x+3.

Answer:

there is an economic principle that states that 1 dollar today is worth more than 1 dollar in the future, since an invested dollar could earn interests and gain value.

For example, we can assume a 6% interest rate (0.5% monthly interest rate), and using the present value formula we can determine the present value of $100:

In order to calculate the value of $100 given to us tomorrow, we would need to determine a daily interest rate = 6% / 360 = 0.00017

since the amount of money is not that large and the interest rate is rather low, the difference in value is not that large. But imagine if you used a 24% interest rate instead of 6% (monthly interest rate = 2%)

as the interest rate increases, the present value decreases.

The person in the at-risk population is much more likely to actually have the disease

Step-by-step explanation:

The probability of a randomly selected doctor having the disease is 1 in 1,000 (P(I)=0.0001).

The probability that a doctor is infected with SARS, given that they tested positive is:

[tex]P(I|+)=\frac{P(I)*0.99}{P(I)*0.99+(1-P(I))*0.01}\\P(I|+)=\frac{0.0001*0.99}{0.0001*0.99+(1-0.0001)*0.01}\\P(I|+)=9.9*10^{-3}[/tex]

The probability of a randomly selected person from the at-risk population having the disease is 20 in 100 (P(I)=0.20).

The probability that a person in the at-risk population is infected with SARS, given that they tested positive is:

[tex]P(I|+)=\frac{P(I)*0.99}{P(I)*0.99+(1-P(I))*0.01}\\P(I|+)=\frac{0.2*0.99}{0.2*0.99+(1-0.2)*0.01}\\P(I|+)=0.962[/tex]
