Answer:

Step-by-step explanation:

If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up.Solution:Probability of an event, P(E) = Number of occurrences where the event takes place / Total number of occurrencesThe probability of 2 heads coming up when three coins are tossed simultaneously is given by the ratio of the number of times a particular outcome occurs to the total number of tosses.Total number of tosses = 200Number of 2 heads outcomes = 72Probability of 2 heads outcomes = Number of 2 heads outcomes / Total number of tosses= 72/200= 9/25

Hey there!

7t - 3 = -59

ADD 3 to BOTH SIDES

7t - 3 + 3 = -59 + 3

CANCEL out: -3 + 3 because it give you 0

KEEP: -59 + 3 because it help solve for the t-value

NEW EQUATION: 7t = -59 + 3

SIMPLIFY IT!

7t = -56

DIVIDE 7 to BOTH SIDES

7t/7 = -56/7

CANCEL out: 7/7 because it give you 1

KEEP: -56/7 because it help solve for the t-value

NEW EQUATION: t = -56/7

SIMPLIFY IT!
t = -8

Therefore, your answer is: t = -8

Answer:

D. 324 in²

Step-by-step explanation:

Given :

Length of shoebox = 12 in

width = 6 in

height = 5 in

The Total surface area of cuboid = 2(lw + lh + wh )

=> 2 (12×5 + 12×6 + 5×6 )

=> 2( 60 + 72 + 30 )

=> 2( 162)

=> 324 in²

Barbara's net loss on the sale of the stocks she purchased last year is 1245.63.

A net loss is earned when the cost price of purchasing the stock is greater than the selling price.

Net loss = cost price - selling price

Cost price = 8500 + (8500 x 1.25%) = 8606.25

Selling price = 7324 + (7324 x 0.5%) = 7360.62

Net loss = 8606.25 - 7360.62 = 1245.63

Here is the complete question: barbara purchased stock last year for 8500 and paid a 1.25% broker fee. she sold it for 7324 and had to pay a .5% broker fee. Compute her net loss.

Answer: 180 inches

Step-by-step explanation:

We can use dimensional analysis. Our desired units are inches per yard. Begin by writing down:

[tex]\frac{12in}{1ft}[/tex]

Then use the conversion factor of feet to yard. The units of feet will cancel giving:

[tex]\frac{12in}{1ft} *\frac{3ft}{1yd}=\frac{36in}{1yd}[/tex]

Multiply the top and bottom by 5 to get:

[tex]\frac{36in}{1yd} *\frac{5}{5} =\frac{180in}{5yd}[/tex]

Answer: 256,1

Step-by-step explanation:

[tex]\sqrt{x} - \sqrt{y} =15\\\sqrt{y} = 49-3\sqrt{x} \\\\\sqrt{x} -(49-3\sqrt{x} ) =15 \\so, x=256\\substitute \{x}\ :\\\\\sqrt{y} = 49-3\sqrt{256} =y=1[/tex]

so, 256=x

and, y=1

Answer:

1, 4 or -1, -4

Step-by-step explanation:

Let the two numbers be x and such that x > y.

According to the first condition:

[tex]x^2 -y^2= 15[/tex]

[tex]\implies x^2 =y^2+15[/tex]......(1)

According to the second condition:

[tex]3x^2 +y^2= 49[/tex]

[tex]\implies 3(y^2+15) +y^2= 49[/tex]

(From equation 1)

[tex]\implies 3y^2+45 +y^2= 49[/tex]

[tex]\implies 4y^2 =49-45[/tex]

[tex]\implies 4y^2 =4[/tex]

[tex]\implies y^2 =\frac{4}{4}[/tex]

[tex]\implies y^2 =1[/tex]

[tex]\implies y =\pm 1[/tex]

When y = 1

[tex]\implies x^2 =(1)^2+15=1+15=16[/tex]

[tex]\implies x =\pm 4[/tex]

When y = -1

[tex]\implies x^2 =(-1)^2+15=1+15=16[/tex]

[tex]\implies x =\pm 4[/tex]

Thus, the required numbers are either 1, 4 or -1, -4

The area of the trapezoid is [tex]\frac{1}{2}(b1+b2)*h[/tex]

Answer:

[tex]\underline{\boxed{\sf \cfrac{-19}{x-5}}}[/tex]

Step-by-step explanation:

[tex]\sf \cfrac{x^2+10+25}{x+5}-\cfrac{x^2-6}{x-5}[/tex]

First, Let's factor the expressions that are not already factored in x^2+10+25/x+5

[tex]\sf \cfrac{(x+5)^2}{x+5}-\cfrac{x^2-6}{x-5}[/tex]

Now, cancel out x+5 in both numerator and denominator:-

[tex]\sf x+5-\cfrac{x^2-6}{x-5}[/tex]

Expand equations to make their denominators the same before adding or subtracting them. Multiply x+5 * x-5/x-5:-

[tex]\sf \cfrac{(x+5)(x-5)}{x-5}-\cfrac{x^2-6}{x-5}[/tex]

Now, Since [tex]\sf \frac{(x+5)(x-5)}{x-5}[/tex] and [tex]\sf \frac{x^2-6}{x-5}[/tex] and similar denominator, we'll subtrac their numerators.

[tex]\sf \cfrac{(x+5)(x-5)-(x^2-6)}{x-5}[/tex]

Answer:

6!/3!=6x5x4x3x2/3x2=6x5x4=120

Step-by-step explanation:

There are L, O, O, P, H, O, L, E; 8 letters in LOOPHOLE. However, three letters repeat: OOO. That means we cannot count them as different and use ! for them.

L,P,H,L,E,O are the letters not double counted. There are SIX letters, so 6!, however, you still have to divide since there are the Os you have to consider.

You have to divide by 3! as they repeat 3 times.

Thus, 6!/3!

"There is a subset of permutations that takes into account that there are double objects or repetitions in a permutation problem. In general, repetitions are taken care of by dividing the permutation by the factorial of the number of objects that are identical" -www. ck12. org > probability > lesson > permutation

The equation tan(mx) = sin(mx)/cos(mx)​ is a trigonometry equation

The trigonometry equation tan(mx) = sin(mx)/cos(mx)​ is true

The equation is given as:

tan(mx) = sin(mx)/cos(mx)​

The tangent of an angle is the ratio of the sine and the cosine of the angle.

This means that:

tan(α) = sin(α)/cos(α)

By comparison, we have:

α = mx

Substitute α = mx in tan(α) = sin(α)/cos(α).

So, we have:

tan(mx) = sin(mx)/cos(mx)​

Hence, the trigonometry equation tan(mx) = sin(mx)/cos(mx)​ is true

Juan created 35 long swordsmen, 35 spearmen and 15 crossbowmen.

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

Let x represnt the number of long swordsmen, y represent the spearmen and z represent the crossbowmen. Hence:

75x + 40y = 4025     (1)

25x + 40z = 1475     (2)

And:

30y + 30z = 1500 (3)
