what is the length if the baseedge labeled X? Will mark brainliest if correct.

Answer:

pls provide with a graph

Step-by-step explanation:

[tex](x + 5)(x - 2) \geqslant 0[/tex]

[tex]x + 5 = 0 \\ x \geqslant - 5 \\ x - 2 = 0 \\ x \geqslant 2[/tex]

The solution of the inequality is x  ≥ -5 and x  ≥ 2.

The graph of the number line is given in the attached image.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

An inequality (x+5)(x-2) ≥ 0

Solving further,

(x+5) ≥ 0 and (x -2)  ≥ 0

x  ≥ -5 and x  ≥ 2

Therefore, the solution of the inequality is x  ≥ -5 and x  ≥ 2.

Answer:

The confidence interval will be shorter

Step-by-step explanation:

Required

How will the confidence interval be affected when n is used instead of n - 1

As sample size n increases, the confidence interval also increases by 1;

i.e.

[tex]df = n- 1[/tex]

However, the confidence interval gets reduced.

This implies that, the higher the degrees of freedom; the shorter the confidence interval.

Shorter. As the degrees of freedom increase, the value for tc decreases.

Answer: D

Step-by-step explanation:

Comparing the standard deviations of each distribution, you have blue < red < yellow.

For any normally distributed random variable X with mean µ and standard deviation σ, we have the property that

Pr[|X - µ| ≤ σ] ≈ 68%

In other words, roughly 68% of a normal distribution lies within 1 standard deviation of the mean. This means the plot of the density of a distribution with a smaller standard deviation forms a tighter peak (like the blue curve), whereas a larger standard deviation would be indicated by a more dispersed, flattened curve (like the yellow one).

Answer:

Yes, I agree

Answer:

507.84

Step-by-step explanation:

ratio 6:4

to use this ratio divide 92 by 2 --> 46

then 6+4 = 10, so 46/10 = 4.6

4.6 x 6 = 27.6

4.6 x 4 = 18.4

27.6 x 18.4 = 507.84

Answer:

x = -7,   y = 5

Step-by-step explanation:

a) x + 9y = 38,   b) 3x + 7y = 14

From a)

x = 38 - 9y ---- (Equation 1)

From b)

{3*(38 - 9y)} + 7y = 14 ----- (From equation 1)

114 - 27y + 7y -14 = 0

100 - 20y = 0

20y = 100

y = 5

From a)

x + (9*5) = 38  (substituting the value of y = 5)

x + 45 = 38

x = 38 - 45

x = -7

Answer:

110

Step-by-step explanation:

Supplementary angles add to 180

3x+5  +2x = 180

Combine like terms

5x +5 = 180

Subtract 5 from each side

5x = 175

Divide each side by 5

5x/5 = 175/5

x =35

DEF = 3x+5

    = 3*35 +5

   = 105+5

  = 110

Answer:

Step-by-step explanation:

1). If the given triangles are similar their corresponding sides will be proportional.

[tex]\frac{8}{a}= \frac{8}{12}=\frac{5}{b}[/tex]

[tex]\frac{8}{a}= \frac{8}{12}[/tex]

[tex]a=\frac{12\times 8}{8}[/tex]

[tex]a=12[/tex]

[tex]\frac{8}{12}=\frac{5}{b}[/tex]

[tex]b=\frac{5\times 12}{8}[/tex]

[tex]b=7.5[/tex]

2). By using proportional relationship in the similar polygons,

[tex]\frac{3}{c}=\frac{6}{8}[/tex]

[tex]c=\frac{8\times 3}{6}[/tex]

[tex]c=4[/tex]

d = 8

c = e = 4

3). If the pentagons are similar their corresponding sides will be proportional.

[tex]\frac{6}{g}=\frac{8}{18}=\frac{10}{h}= \frac{8}{I}=\frac{6}{f}[/tex]

[tex]\frac{6}{g}=\frac{8}{18}[/tex]

[tex]g=\frac{18\times 6}{8}[/tex]

[tex]g=13.5[/tex]

[tex]\frac{8}{18}=\frac{10}{h}[/tex]

[tex]h=22.5[/tex]

[tex]\frac{8}{18}=\frac{6}{f}[/tex]

[tex]f=13.5[/tex]

[tex]\frac{8}{18}= \frac{8}{I}[/tex]

[tex]I=18[/tex]

Answer:

Step-by-step explanation:

x+35=2x(opposite angles of a parallelogram are equal)

35=2x-x

35=x

So this is complicated, but to get a general idea simple we use common sense and say its bigger than 4, since its length is bigger than the supposed 4 length. So then we get  the options 6, 5, and 24. Now we can do some basic math and figure that the circle radius is around 4 so its probably 6 or 5. Slim change of 24.

Answer: d. 0.55

Step-by-step explanation:

The given probability distribution:

Number of Goals     0            1            2          3           4

Probability             .05           .15        .35       .30           .15

The probability that in a given game the Lions will score less than 3 goals

= probability that in a given game the Lions will score less than or equal to 2

= 0.5+0.15+0.35

= 0.55

Hence, the correct option is d. 0.55

Answer:

  c.  $20.23

Step-by-step explanation:

The overhead cost per labor hour is found by dividing overhead costs by labor hours:

  $163,900/(8100 h) = $20.23 /h

The factory overhead rate is $20.23 per labor hour.

Answer:

The rate of depreciation is 11.87% per year.

Step-by-step explanation:

Given that a brand new car was purchased for $ 28,000 in year 2000, and the car value has dropped to $ 20,000 in year 2003, to determine what could be considered as the rate of depreciation, the following calculation must be performed:

20,000 x (1 + X / 1) ^ 3 = 28,000

20,000 x X ^ 3 = 28,000

20,000X ^ 3 = 28,000

X = 1.1187

Therefore, the rate of depreciation is 11.87% per year.

Answer:

94 square inches I don't have an explanation

The differential equation

dy/dx = x sin(x ²) / y

is separable as

y dy = x sin(x ²) dx

Integrate both sides:

∫ y dy = ∫ x sin(x ²) dx

∫ y dy = 1/2 ∫ 2x sin(x ²) dx

∫ y dy = 1/2 ∫ sin(x ²) d(x ²)

1/2 y ² = -1/2 cos(x ²) + C

Solve for y implicitly:

y ² = -cos(x ²) + C

Given that y = 1 when x = 0, we get

1² = -cos(0²) + C

1 = -cos(0) + C

1 = -1 + C

C = 2

Then the particular solution to the DE is

y ² = 2 - cos(x ²)

Solving explicitly for y would give two solutions,

y = ± √(2 - cos(x ²))

but only the one with the positive square root satisfies the initial condition:

√(2 - cos(0²)) = √1 = 1

-√(2 - cos(0²)) = -√1 = -1 ≠ 1

So the unique solution to this DE is

y = √(2 - cos(x ²))
