Step-by-step explanation:

To find the original number of cars per color in the inventory, divide the sold number of cars by the percent of the inventory.

red: 20 = 10/0.5

white: 30 = 21/0.7

black: 25 = 19/0.76

silver: 40 = 10/0.25

Answer:

gonna guess you're asked to find the measures of two interior angles given at least one exterior angle and one interior angle.

Two angles on the same line are SUPPLEMENTARY. Let's say your exterior angle is 95 degrees. That makes the corresponding interior angle 180 - 95 = 85 degrees. If your other interior angle is 79 degrees, then your last interior angle is 180 - (85 + 79) = 16 degrees.

The measure of x and y is -

x = 40°

y = 50°

We have a figure shown in the image.

We have to determine the measure of angle x and angle y.

The relation states that the sum of the any two sides of a triangle is always greater than the third side. Mathematically -

a + b > c

According to the question -

y + (2x + 50)° = 180°            [supplementary angles have a sum of 180°]

2x + y = 130°

y = 130° - 2x

Therefore, in the right - angled triangle -

x + 130° - 2x + 90° = 180°     [the sum of angles of a Δ = 180°]

- x + 220° = 180°

x = 220° - 180°

x = 40°

and

y = 130 - 2 x 40 = 50°

Hence, the measure of x and y is -

x = 40°

y = 50°

Answer:

120 sq feet

Step-by-step explanation:

1. 8 x 10 = 80

2. 8 x 5 = 40

3. 80 + 40 = 120 ft2 (sq feet)

Use the formula below:

[tex] \large \boxed{h = - \frac{b}{2a} }[/tex]

From the given equation:

[tex] \large{y = 2 {x}^{2} - 6x + 2}[/tex]

Substitute a = 2 and b = -6 in the formula.

[tex] \large{h = - \frac{ - 6}{2(2)} } \\ \large{h = - \frac{ - 6}{4} } \\ \large{h = - \frac{ - 3}{2} \longrightarrow \boxed{h = \frac{3}{2} }}[/tex]

Since h is from (h,k). From an ordered pair, h = x and k = y. When answering the axis of symmetry, you should answer in term of x.

Answer:

No real roots

Step-by-step explanation:

Given

[tex]6x^2 + 6x + 3 = 0[/tex]

Required

The number of solution

The discriminant (d) for [tex]ax^2 + bx + c = 0[/tex] is:

[tex]d = b^2 - 4ac[/tex]

So, we have:

[tex]d = 6^2 - 4*6*3[/tex]

[tex]d = 36 - 72[/tex]

[tex]d = -36[/tex]

Since [tex]d <0[/tex], then the equation has no real roots

Answer:

4/3

Step-by-step explanation:

Out of the six sides 3 are odd and there's 5 numbers greater than 1. Basically these turn to the fractions 3/6 and 5/6 (these fractions stand for the probability they get rolled on this die).

Since the question says OR and not AND you add these fractions!

3/6 + 5/6 = 4/3

Step-by-step explanation:

Combination has to do with the idea of selection. Here we need to select a president, a secretary, and a treasurer.

This means to select three out of twenty five persons.

From;

nCr = n! / ((n – r)! r!)

n = the number of items.

r = how many items are taken at a time.

Thus we have;

25C3 = 25!/(25 - 3)! 3!

=

1.6× 10^25/1.1×10^21 × 6

Answer:

The table should measure diagonally about 41.23 inches.

Step-by-step explanation:

To find the diagonal of a rectangle we use the formula :

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

A and B both represent the side lengths of the rectangle, while C is the diagonal part. Knowing this formula, let's plug in the values for A and B and see what happens.

[tex]32^{2}[/tex] + [tex]26^{2}[/tex] = [tex]c^{2}[/tex]

1024 + 676 = [tex]c^{2}[/tex]

1700 = [tex]c^{2}[/tex]

The square root of 1700 is (rounded to the hundreth's place) = 41.23

The answer is below

Step-by-step explanation:

The empirical rules states that for a normal distribution, 68% of the data falls within one standard deviation from the mean, 95% falls within two standard deviation from the mean and 99.7% falls within three standard deviations from the mean.

Given that:

mean (μ) = 71 inches, standard deviation (σ) = 4.3 inches

One standard deviation = μ ± σ = 71 ± 4.3 = (66.7, 75.3)

Two standard deviation = μ ± 2σ = 71 ± 2*4.3 = (62.4, 79.6)

Three standard deviation = μ ± 3σ = 71 ± 3*4.3 = (58.1, 83.9)

Answer:

c. As sample size increases, standard error decreases.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

Thus:

The standard error is inversely proportional to the square root of the sample size, that is, as the sample size increases, the standard error decreases, and the correct answer is given by option c.
