Solve for X. Find the length of angle

The probability that a randomly selected woman does not have red/green colorblindness is 0.98 (98%).

The probability of not having red/green colorblindness is the inverse of the probability of having colorblindness. The probability of having red/green colorblindness is given as 0.92%. To calculate the probability of not having red/green colorblindness, subtract the probability of having colorblindness from 1. 1 - 0.92 = 0.08. This means that the probability of not having red/green colorblindness is 0.08, or 8%. To convert this to a percentage, multiply by 100. 0.08 x 100 = 8%. The probability of not having red/green colorblindness is 8%. This can also be written as 0.98 (98%).

Step-by-step explanation:

The annual interest rate is 1.2% if Stanley invests £7500 for 4 years in a savings account.

percentage, a relative value indicating hundredth parts of any quantity.

We can use the formula for compound interest:

[tex]A = P (1 + r/n)^(^n^t^)[/tex]

where A = the final amount, P = the principal (initial investment), r = the annual interest rate (as a decimal), n = the number of times the interest is compounded per year and t = the time in years

We know that P = £7500, t = 4 years, and A = £7866.53.

Let n is 1

Plugging in the values we know, we get:

£7866.53 = £7500 (1 + r/1)⁴

Simplifying the equation:

(1 + r)⁴ = 1.04887

Taking the fourth root of both sides:

1 + r = 1.012

Subtracting 1 from both sides:

r = 0.012 or 1.2%

Therefore, the annual interest rate is 1.2%.

(−5, 2) is point lie on a line that passes through the origin with a slope of −2/5

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find the points lie on a line that passes through the origin with a slope of −2/5

The line passes through (0, 0) and (x, y) form a slope of -2/5

-2/5=y/x

So y is 2 and x is 5.

Hence, (−5, 2) is points lie on a line that passes through the origin with a slope of −2/5

Answer:

8.2%

Step-by-step explanation:

To find the sales tax percentage, we need to determine how much of the total price was due to sales tax. To do this, we can subtract the price of the cupboard from the total price:

$92.82 - $85.78 = $7.04

So the sales tax was $7.04. We can then divide the sales tax by the price of the cupboard and multiply by 100% to find the sales tax rate as a percentage:

$7.04 / $85.78 * 100% = 8.2%

Rounding to the nearest tenth, the sales tax rate was 8.2%.

Answer:

8.2% (rounded to the nearest tenth)

Step-by-step explanation:

$92.82-$85.78= $7.04

100%= $85.78

1%= $85.78÷100

= $0.8578

$7.04÷$0.8578= 8.2% (rounded to the nearest tenth)

The measure of the angle X is equal to 38.7° to the nearest tenth using the trigonometric ratio of tangent of X.

The trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.

For the tangent of X equal, we can make x the subject by finding the tan inverse of opposite divided by the adjacent side as follows:

tan X = 8/10 {opposite/adjacent}

X = tan⁻¹(0.8)

X = 38.6598

Therefore, the measure of the angle X is equal to 38.7° to the nearest tenth using the trigonometric ratio of tangent of X.

Expressions consist of basic mathematical operators. The product of [tex]\frac{1}{2x} -\frac{1}{4}[/tex] & [tex]5x^{2} -2x +6[/tex] is not equal to the product of [tex]\frac{1}{2x} -\frac{1}{4}[/tex] and [tex]5x^{2} -2x +6[/tex]

Product of an Equation:

In mathematics, a product is a number or quantity obtained by multiplying two or more numbers. Example: 4 × 7 = 28, where the number 28 is said to be the product of 4 and 7. Another example: 6 times 4 is 24, so 6 multiplied by 4 is 24. The product of two positive numbers is a positive number, as if the product of two negative numbers is also positive (e.g., -6 × -4 = 24).

Now,

(A) We need to find the product of two given expressions.

[tex]\frac{1}{2x} -\frac{1}{4}[/tex] ×  [tex]5x^{2} -2x +6[/tex]

To multiply two given expressions, first multiply the first term in the first parenthesis by the entire expression in the second term, then do the same for the second term in the first parentheses.

[tex]\frac{1}{2x} -\frac{1}{4}[/tex] × [tex]5x^{2} -2x +6[/tex]

⇒ [tex]\frac{1}{2x} * [5x^{2} -2x +6] - \frac{1}{4} * [5x^2 - 2x +6][/tex]

⇒ [[tex]\frac{1}{2x} * 5x^2[/tex] - [tex]\frac{1}{2x} *2x[/tex] + [tex]\frac{1}{2x}* 6[/tex] ] - [ [tex]\frac{1}{4} * 5x^2 + \frac{1}{4} * 2x - \frac{1}{4}*6[/tex]]

Now, simplify the equation:

[tex]\frac{5x}{2} -1 + \frac{3}{x} - \frac{5x^2}{4} +\frac{x}{2} +\frac{3}{2}[/tex]

Rearranging the equation:

[tex]-\frac{5x^2}{4} + \frac{6x}{2} -2.5 +\frac{3}{x}[/tex]

Thus, the product of the two expressions is [tex]-\frac{5x^2}{4} + \frac{6x}{2} -2.5 +\frac{3}{x}[/tex].

(B) To compare the two expressions we will find the value of the two given expressions,

[tex]\frac{1}{2x} -\frac{1}{4} * 5x^{2} -2x +6[/tex] = [tex]-\frac{5x^2}{4} + \frac{6x}{2} -2.5 +\frac{3}{x}[/tex]

For the value of:

[tex]\frac{1}{4x} - \frac{1}{2} * 5x^{2} -2x +6[/tex]

simplifying the equation:

    [tex]\frac{1}{4x} - \frac{1}{2} * 5x^{2} -2x +6[/tex]

⇒ [tex][\frac{1}{4x} * (5x^{2} -2x +6)] - [\frac{1}{2} * (5x^{2} -2x +6)][/tex]

⇒ [tex]-\frac{5x^2}{2} + \frac{9x}{4} + 3.5 +\frac{3}{2x}[/tex]

As you can see, the result of the product of the two expressions is different.

Answer:

Step-by-step explanation:

Substituting v = 2 and w = 16 in the expression w - 7|v|, we get:

w - 7|v| = 16 - 7|2|

We need to evaluate the absolute value of 2, which is simply 2. Therefore, we can simplify the expression as:

16 - 7|2| = 16 - 7(2) = 16 - 14 = 2

So, w - 7|v| = 2 when v = 2 and w = 16.

Answer: The tip is 20% of the cost including tax. Thus .20 * X=3.50.Divide both sides of the equation by .20..20 divided into .20 = 1, so “X” = 1.And 3.50 divided by .20 = 17.50 So X = 17.50, cost of the meal plus the tax.The tax is .07, so we know that 100% of the meal cost PLUS 7% of the meal cost is 107% of the meal cost.

⇒  (7, 0) and (20, 18)

Thus, Use these points to find the slope of the line is,

⇒ m = (18 - 0) / (20 - 7)

⇒ m = 18 / 13

Use the found slope and one of the points in the point-slope form of the linear equation to find an equation for the line of best fit:

⇒ y - y₁ = m (x - x₁)

⇒ y - 0 = 18/13 (x - 7)
