2 tablets, 3x per day for 10 days

Answer:

5

Step-by-step explanation:

this is basic algebra so it's important to understand this concept now. you need to combine like terms so 3x-6=9 becomes 3x=15 (you add the 6 to add like terms). You then divide the 3 from 3x on both sides to get x=5

The value of x makes the equation 3x - 6 = 9 true is: x = 5.

Here, we have,

given that,

the equation is: 3x - 6 = 9

so have,

3x-6=9

We need to combine like terms

=> 3x = 9 + 6

(we add the 6 to add like terms).

becomes, => 3x=15

we then divide the 3 from on both sides

=> 3x/3 = 15/3

we get

=> x=5

Answer:

x=75

Step-by-step explanation:

[tex]We\ are\ given\ that:\\AD\ is\ the\ altitude\ of\ \triangle ABC\\Hence,\\ADC=90[As\ altitudes\ intersect\ the\ base\ side\ at\ 90]\\Hence,\\As\ ADC=(x+15)\ and\ ADC=90\\x+15=90\\x=90-15\\x=75[/tex]

This is only the value of x in terms of AD being an altitude, and is independent off the sides.

Answer:

Step-by-step explanation:

What you are being told is that 3x - 7 is twice as big as x. You can see that because ST (for example) is cut into 2 equal parts. So is UT (cut into two equal parts). So the parts of the Big Triangle (SUT) are twice as Big as the parts of the small triangle DET

So multiply x by 2

3x - 7 = 2x                                Add 7 to both sides

3x - 7  + 7 = 2x + 7

3x = 2x + 7                               Subtract 2x from both sides

3x-2x = 7

x = 7

The table of values is given as

Time, t         0        1      1.5       2.5    3  

Height, h    280   264   244    180   136

Next, we enter the above values in a graphing calculator to create the scatter plot

See attachment for the scatter plot created using the graphing calculator

From the graphing calculator, we have

h = -16t^2 + 280

This means that

h = 0

So, we have

-16t^2 + 280 = 0

Divide through by -16

So, we have

t^2 - 17.5 = 0

This gives

t^2 = 17.5

Take the square roots

t = 4.18

Hence, the sponge will hit the ground after 4.18 seconds

Answer:

A) Mean = 135 Variance = 62 Standard Deviation = 8

Step-by-step explanation:

Given that :

Proportion (p) = 54%

Sample size (n) = 250

Using Normal approximation :

Mean = np

Mean = 250 * 0.54 = 135

Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46

Variance = (250 * 0.54 * 0.46) = 62.1 = 62

Standard deviation = √variance = √62.1

Standard deviation = 7.8803553 = 8

Answer:

|x - 13| = 5

Step-by-step explanation:

Think of absolute value as a distance. For example, |5| can be written as |5 - 0| = 5 since the distance between 5 and zero on the number line is 5. Also, |-5| which is the same as |-5 - 0| is also 5 since the distance between -5 and zero on the number line is 5.

Since you want an absolute value equation with solutions 8 and 18, think of which number is the same distance from both 8 and 18 on the number line? Find the average of 8 and 18, (8 + 18)/2 = 13. 13 is the same distance from both 8 and 18. 13 is 5 units away from both 8 and 18. Now you need an equation that is looking for the numbers x which are 5 units distance from 13.

|x - 13| = 5

Answer:

x = 11

Step-by-step explanation:

5 + 3x - 37 = 6x + 23 - 8x

3x - 6x + 8x = 37 - 5 + 23

11x - 6x = 60 - 5

5x = 55

x = 55/5

x = 11

Thus, the value for x is 11

The distance between points AB at A(2, 5) and B(2, 10) is 5 units

An equation is an expression that shows the relationship between two or more numbers and variables.

The distance between two points A(x₁, y₁) and B(x₂, y₂) on the coordinate plane is:

[tex]AB=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

Let us assume that AB has coordinate at A(2, 5) and B(2, 10), hence:

The amount to invest on  January 1st so that you have $1000 by June 1st of the same year is $992.54

What is monthly compounding?

Monthly compounding means that the interest is computed every month, in essence, the interest in January, March and May would be 1% divided by 12 months in a year whereas the interest in February, April, would be 3% divided 12 months making a year.

FV=PV*(1+r1)*(1+r2)*(1+r3)+(1+r4)*(1+r5)

FV=the future value June 1st of the same year=$1000

PV=the amount that needs to be invested=unknown

r1=January interest rate=1%/12=0.00083333333333

Answer:

21 / 143

Step-by-step explanation:

Given that:

Number of Eastern conference reps = 8

Number of western conference rep = 7

Probability of selecting 3 from Eastern reps and 2 from western reps

Probability = required outcome / Total possible outcomes

Total possible outcomes:

selection to be made = 3+ 2 = 5

Total Number of players = 8 +7 = 15

Total possible outcomes

Using combination formula :

nCr = n! / (n-r)!r!

15C5 = 15! / 10!5! = (15 * 14 * 13 * 12 * 11) / (5*4'3*2*1) = 360360 / 120 = 3003

Total possible outcomes = 3003

Required outcome :

8C3 * 7C2

8C3 = 56 ; 7C2 = 21

8C3 * 7C2 = 56 * 21 = 1176

required outcome / Total possible outcomes

= 1176 / 3003

= 21 / 143

Using the hypergeometric distribution, it is found that the probability is:

c. 56/143

The players are selected from the sample without replacement, hence, the hypergeometric distribution is used.

Hypergeometric distribution:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability is P(X = 3), hence:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 3) = h(3,15,5,8) = \frac{C_{8,3}C_{7,2}}{C_{15,5}} = 0.3916[/tex]

Answer:

A: 0.1003

Step-by-step explanation:

We are given;

Population mean; μ = 56.8

Population size; n = 51

Population standard deviation; σ = 12.3

We want to find; P(x > 59)

We will use the z-score formula.

z = (x - μ)/(σ/√n)

z = (59 - 56.8)/(12.3/√51)

z = 1.28

From z-distribution table attached, we have; P(z < 1.28) = 0.8997

Thus;

P(z > 1.28) = 1 - 0.8997 = 0.1003
