First we have to subtract 14,443 from 98,232 since deposit means take out. Now that would become 83,789 so that would continue from Feb to April that would be about 3 times so we have to keep subtracting 14,443 or just do 14,442 since we have to do this 3 times and then subtract 98,232 from 43326(the answer from 14,442*3)  and we get 54906 as our final answer!

Answer:

Step-by-step explanation:

PQRS

PQ + QR + RS + PS = 186

RS = SP - 7

PQ = RS = x - 7

QR =  PS = x

2x + 2(x - 7) = 186

4x = 200

x = 50

PQ and RS = 43

QR and SP are 50

2+120 =122

Answer:

first, you need to get y on one side. So, because the x is negative it becomes positive when you switch it to the other side. 3y= 9x+5. You then need to divide all parts by 3. 3/3= 1 so thats just y. 9/3 is 3 so thats 3x. then 5/3 is a fraction that you can write as just 5/3 or 1 and 2/3. That would leave you with y= 3x + 5/3. Then x (3) is your slope. and what you add to it (5/3) is your y int.

Answer:

x=3,5

Explanation:

x2−8x+15=0

Try to express the terms of the equation in square form.

Adding 16 both sides of the equation,

(x2−2⋅x⋅4+42)+15=16

or,(x−4)2+15−16=0

or,(x−4)2−1=0

or,(x−4)2−12=0

This is the a2−b2=(a+b)(a−b)form.

(x−4+1)(x−4−1)=0

or,(x−3)(x−5)=0

Now, equate both the terms to zero since both of them when multiplied, give zero.

Either,

x−3=0

∴x=3

Or,

x−5=0

∴x=5

Ans:x=3,5 Hope this helpsXD...!!

Answer:

3<x<5

Step-by-step explanation:

an Univariate quadratic polynomial can be divided into the product of two first order equations

In this example, x2 - 8x + 15 =  (x-3) * (x-5) <0

as a result. the answer is 3< x <5

Answer:

a. The 95% confidence interval is 0.799<p<0.847

b. The sample size n is 622

Step-by-step explanation:

A

P^ = 823/1000

= 0.823

At 95% confidence interval

P^ +- z-alpha/2√p^(1-p^)/n

z-alpha/2 = 1.96

When we insert values we get:

0.823+-1.96√0.823(1-0.823)/1000

= 0.823+-1.96√0.000145671

= 0.823+-1.96(0.012069)

= (0.8467, 0.7993)

The 95% confidence interval is 0.799<p<0.847

B.

We are to compute the sample size here.

The formula and full calculation has been done in the attachment.

4268.4x0.145671

= 621.78

= 622

n = 622

Answer:

9/10ths of a mile. Or 0.9 miles.

Step-by-step explanation:

To get the total it's helpful to look at it in decimals:

2/5 mile = 0.4 miles (1 mile divided by 5 = 0.2 miles, times that by 2)

1/2 mile = 0.5 miles

Add them together = 0.9 miles.

Which is 9/10ths of a mile.

The total distance walked will be equal to [tex]\frac{9}{10}[/tex] miles or 0.9 miles.

It is given that you walk 2/5 miles to a clothing store and then walk another 1/2 miles to a music store.

We have to find out the total distance in miles that you have walked.

What do you mean by fractions ?

A fraction can be defined as a portion or part of any quantity or it defines a part of a whole.

As per the question ;

You walk 2/5 miles to a clothing store

and

then ; walk another 1/2 miles to a music store.

To find out the total distance walked by you in total , we need to add both the distances given in the question.

i.e.,

Total distance will be ;

= [tex]\frac{2}{5}[/tex] + [tex]\frac{1}{2}[/tex]

= [tex]\frac{4+5}{10}[/tex]

= [tex]\frac{9}{10}[/tex] miles

or

= 0.9 miles

Thus , the total distance walked will be equal to [tex]\frac{9}{10}[/tex] miles or 0.9 miles.

Answer:

Angle 1: 131

Angle 6: 49

Answer:

m∠1 = 131º

m∠6 = 49º

Step-by-step explanation:

So we know that a straight line is equal to 180º and we already know the measure of angle 8 (49º) so to find the measure of angle 7, we just subtract 49 from 180.

180 - 49 = 131

So m∠7 = 131º

Now because of the alternate exterior angle rule, we can now find out that m∠7 is the same as m∠1

Now for the measurement of angle 6, we know that it's 49º because of the vertical angles rule.

Answer: 42v-59

Step-by-step explanation:

Combine like terms

29v- -13v= 42v

The negative sign turns 59 into -59

The value of the equation is A = 42v - 59

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 29v ) - ( -13v + 59 )   be equation (1)

On simplifying the equation , we get

A = 29v - ( -13v ) - 59

On further simplification , we get

A = 29v + 13v - 59

The value of A = 42v - 59

Therefore , the value of A is 42v - 59

Hence , the equation is A = 42v - 59
