(25 - 6.25) + (5 x 3)²

Answer:

I think it would be c 160

Step-by-step explanation:

Answer:

The answer is C) 160ft2

Step-by-step explanation:

I got the answer because if you multiply the number of feet that make up that one side of the tent, you get 40. However, you need the to find out the feet of the whole tent, and there are four sides of the tent, so you'd have to multiply 40 by four to get the total amount of feet for the whole tent which comes out to 160.

Answer:

Step-by-step explanation:

6(x+1) = -2(3x+9)

6x+6 = -6x-18

6x+6x+6-6 = -6x+6x-18-6

12x=-24

x= -2

Answer:

0.9772 = 97.72% probability that a randomly generated value of X is greater than a randomly generated value of Y

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

[tex]\mu_X = 45, \sigma_X = 4, \mu_Y = 35, \sigma_Y = 3[/tex]

What is the probability that a randomly generated value of X is greater than a randomly generated value of Y

This means that the subtraction of X by Y has to be positive.

When we subtract two normal variables, the mean is the subtraction of their means, and the standard deviation is the square root of the sum of their variances. So

[tex]\mu = \mu_X - \mu_Y = 45 - 35 = 0[/tex]

[tex]\sigma = \sqrt{\sigma_X^2+\sigma_Y^2} = \sqrt{25} = 5[/tex]

We want to find P(X > 0), that is, 1 subtracted by the pvalue of Z when X = 0. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0 - 10}{5}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

1 - 0.0228 = 0.9772

0.9772 = 97.72% probability that a randomly generated value of X is greater than a randomly generated value of Y

Answer:

Replace all occurrences of x x in x−y=5 x - y = 5 with 7−y 7 - y . x=7−y x = 7 - y. (7−y)−y=5 ( 7 - y ) - y = 5. Subtract y y from −y - y . x=7−y x = 7 - y. 7−2y=5 7

Step-by-step explanation:

Step-by-step explanation:

Given

[tex]h(t)=(139kt)^2-69t+80[/tex]

For roots [tex]h(t)=0[/tex]

[tex](139kt)^2-69t+80=0\\t=\dfrac{69\pm\sqrt{(-69)^2-4\times (139k)^2(80)}}{2\times 139}\\[/tex]

[tex]t=\dfrac{69\pm\sqrt{4761-6182720k^2}}{278}[/tex]

Larger root: [tex]t=\dfrac{69+\sqrt{4761-6182720k^2}}{278}[/tex]

smaller root: [tex]t=\dfrac{69-\sqrt{4761-6182720k^2}}{278}[/tex]

For exactly one root D=0

i.e. [tex]4761-6182720k^2=0\\\\k=\dfrac{69}{139\times 4\times 2\times \sqrt{5}}\\k=0.0277[/tex]

Step-by-step explanation:

Answer:

55

Step-by-step explanation:

Table - 450 + 540 = 990

Graph - 850 + 85 = 935

On the table eleven would equal 990.

On the graph eleven would equal 935.

990 - 935 = 55

So to solve equations like this, you want to isolate the variable first. Then you begin to simplify by dividing each side of the equation by a factor that does not contain a variable.  

Answer:

1 / 7

Step-by-step explanation:

Given :

Number of shirts in closet = 10

Number of striped shirt = 5

Number of plaid = 3

Probability of choosing 2 plaid shirts and 2 stripped shirt

Probability = required outcome / Total possible outcomes

Total possible outcomes = 10C4

Required outcome :

2 plaid shirt from 3 = 3C2

2 stripped shirts from 5 = 5C2

Hence,

P(choosing 2 plaid and 2 stripped shirt) :

(3C2 * 5C2) / 10C4

Recall:

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

Using calculator :

(3C2 * 5C2) / 10C4

= (3 * 10) / 210

= 30 / 210

= 1 / 7

Answer:

D) y = 4x + 2

Step-by-step explanation:

Explanation:-

Given ( 0, 2) ( -1 , -2 )

Given in equalities     y = 4x + 2

    put point  (0,2)  in equation y = 4x +2

                                                 2 = 4(0) +2

                                                2 = 2

Therefore satisfies the point (0,2) equation   y = 4x +2

 put point  (-1,-2)  in equation y = 4x +2

                                               -2 = 4(-1)+2

                                              -2  = -2

Therefore satisfies the point (-1,-2) equation   y = 4x +2

Answer:

$80.75

Step-by-step explanation:

From the question, we are given the following parameters

Amount borrowed (principal)=$3800

Time=3 months =1/4 years

Rate = 8.5%

Required

Interest paid by the man

Using the simple interest formula;

SI= Principal*Rate*Time/100

SI=3800*8.5*0.25/100

SI=38*8.5*0.25

SI=$80.75

Hence the man paid $80.75 for the use of the money
