Baldomero’s solution to an equation is show below

Answer:

(x,y) = (25,15)

Step-by-step explanation:

In a parallelogram, alternate angles are equal, so

[tex]\left \{ {{3x-8=4y+7} \atop {4x+13=5x-12}} \right.[/tex]

From the latter equation we obtain [tex]x= 13 + 12 = 25[/tex]. So substituting in the former equation gives

[tex]75-8 = 4y + 7\\4y = 60\\y = 15[/tex]

Answer:

14.9336

Step-by-step explanation:

Given that :

Mean = 10

Standard deviation = 2.8

To simulate a pizza delivery time with a random z - value of 0.961

Using the Z - probability calculator :

To find the x value corresponding to Z = 0.961

P(Z < x) ; P(Z < x) = 0.961 = 1.762

Simulated delivery time for the random number generated :

Mean + (Zscore * standard deviation)

10 + (1.762 * 2.8)

10 + 4.9336

= 14.9336

Step-by-step explanation:

Answer:

8/9

Step-by-step explanation:

It can sometimes be difficult to divide fractions, such as 2/3 divided by 3/4! When we divide two fractions, such as 2/3 ÷ 3/4, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other. We also simplify the answers to fraction problems whenever possible.

Answer:

D= 110,400

Step-by-step explanation:

$48,000 is what she made last month and needs to make 230% more which you can think as a decimal of 2.30

so then you do 48,000*2.30= $110,400

Answer:

Step-by-step explanation:

L = 5 m

area = L×W = 176 m²

5W = 176

W  = 176/5 = 35.2 m

Answer:

[tex]M∠LOM = \boxed{48}[/tex]

Step-by-step explanation:

[tex]M∠LOM + m∠MON = 180 \\ 7x-92 + 6x+12 = 180 \\ 13x - 80 = 180 \\ 13x = 180 + 80 \\ 13x = 260 \\ \boxed{ x = 20} \\ (7x - 92 )= 140 - 92 = \boxed{48} \\ [/tex]

Answer:

1) 2(8) +32 = 48  2) 5-3x   3) 9x+15

Step-by-step explanation:

For the first equation, you do PEMDAS which is parenthesis, exponents, multiplication/division, addition/subtraction. So, you multiply first. For the second problem, you subtract 5 because you see that in the equation, and product of 3 and a number which would be x since it is unknown. For the last equation, you would use the distributive property to do 3(3x) and 3(5) to get 9x+15.

Answer:

Step-by-step explanation:

5x + 2x > 14= x>2

5x + 2x < 14= x<2

5x + 2x ≤ 14= x≤2

5x + 2x ≥ 14= x≥2

Answer:

Step-by-step explanation:

Fishman, Goron, Smith, other

:::::

votes for Goron = 35% of 280 = 0.35×280 = 70

:::::

10% of 280 = 0.10×280 = 28 ≠ 40

The estimate was inaccurate

Answer:

0.2857 = 28.57% probability that in a year the shares will be selling between $21 and $24

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.

The price is approximately normally distributed with a mean of 20 and a standard deviation of 2.

This means that [tex]\mu = 20, \sigma = 2[/tex]

What is the probability that in a year the shares will be selling between $21 and $24

This is the pvalue of Z when X = 24 subtracted by the pvalue of Z when X = 21. So

X = 24:

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

[tex]Z = \frac{24 - 20}{2}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a pvalue of 0.9772

X = 21:

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

[tex]Z = \frac{21 - 20}{2}[/tex]

[tex]Z = 0.5[/tex]

[tex]Z = 0.5[/tex] has a pvalue of 0.6915

0.9772 - 0.6915 = 0.2857

0.2857 = 28.57% probability that in a year the shares will be selling between $21 and $24
