Explanation:
Given
\(4^{\frac{1}{2} }*\frac{2}{\sqrt[4]{16} } -10\div 2\)
Lets evaluate the given expression.
Remember to use PEMDAS.
In the second term, rewrite \(16\) as \(2^4\).
\(4^{\frac{1}{2} }*\frac{2}{\sqrt[4]{2^4} } -10\div 2\)
Pull terms out from under the radical, assuming positive real numbers, then simplify.
\(4^{\frac{1}{2}} *\frac{2}{2} -10\div 2\\4^{\frac{1}{2}} *1-10\div 2\\4^{\frac{1}{2}}-10\div 2\)
Rewrite \(4\) as \(2^2\).
\((2^2)^{\frac{1}{2}} *\frac{2}{2} -10\div 2\)
We can use the power rule to multiply exponents.
The power rule is
\((a^b)^c=a^b^c\)
\(2^{2\left(\frac{1}{2}\right) } *\frac{2}{2} -10\div 2\)
Cancel the common factor of 2.
\(2^1*\frac{2}{2} -10\div 2\)
Any number to the power of 1 stays the same.
\(2*\frac{2}{2} -10\div 2\)
\(\frac{2}{2}\) is equal to \(1\)
\(2*1 -10\div 2\)
Any number multiplied by 1 stays the same.
\(2-10\div 2\)
Divide \(10\) by \(2\).
\(2-5\)
Subtract \(5\) from \(2\).

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place
Answer:
To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:
Standard Error = Standard Deviation / √(Sample Size)
= 92 / √(90)
≈ 9.685
Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.
Now we can calculate the confidence interval:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
= 1700 ± (1.96 * 9.685)
Lower Limit = 1700 - (1.96 * 9.685)
≈ 1679.69
Upper Limit = 1700 + (1.96 * 9.685)
≈ 1720.31
Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

Explanation:
Consider the following figure ABDC with diagonal BC. Sides AB and DC are congruent angle A is congruent to angle D and sides AC and DB are congruent
Quadrilateral ABCD is both a parallelogram and a rhombus.
The figure ABDC with diagonal BC, with the congruent sides AB and DC, angle A is congruent to angle D, and sides AC and DB are congruent is a parallelogram. This is based on the definition of a parallelogram which is a quadrilateral with opposite sides that are parallel and congruent to each other.
Also, opposite angles of a parallelogram are congruent. Therefore, angle A and angle C are congruent. Additionally, angle B and angle D are also congruent because they are opposite angles of a parallelogram.The diagonal of a parallelogram cuts it into two congruent triangles.
Triangle ABD and triangle CBD are congruent triangles, since their sides are congruent, and angles A and D, and angles B and C, are congruent by the given information.
Therefore, their included angles ABD and CBD are also congruent. Because their opposite sides are congruent, quadrilateral ABCD is a rhombus. A rhombus is a parallelogram with all sides congruent. This implies that sides AB, BC, CD, and DA are all equal.
In conclusion, quadrilateral ABCD is both a parallelogram and a rhombus.

The flag of a country contains isosceles triangle. (Recall that an isosceles triangle contains two angles with the same measure.) If the measure of the third angle of the triangle is 15° more than the measure of either of the other two angles, find the measure of each angle of the triangle. (Recall that the sum of the measures of the angles of a triangle is 180°.)
Answer:
The 3 angles are 55°, 55° and 70°
Explanation:
Let the angles of the triangle be a, a and c since two of the angles are the same we can use the same letter to describe the relationships
Sum of all angles of a triangle = 180
a + a + c ==> 2a + c = 180 (1)
We also know c = a + 15
Substituting for c in equation (1) yields
2a + (a + 15) = 180 ==> 3a + 15 = 180 ==> a = (180-15)/3 = 165/3 55°
c = 55 + 15 = 70°
Therefore the 3 angles are 55°, 55° and 70°

In the figure below, AB=BC, What is the area of triangle ABC? Studying for ACT please help
Answer:
The area of ΔABC = 25 (E)
Explanation:
⭐What is the formula for the area of a triangle?
\(area = \frac{1}{2}(bh)\)b = base of the triangleh = height of the triangleIf AB = BC, then BC = \(5\sqrt{2}\).
If BC = \(5\sqrt{2}\), then ∠A = 45°.
Utilize the triangle sum theorem to solve for ∠B.
⭐What is the triangle sum theorem?
the sum of all the angles of a triangle equals to 180 degrees∠A + ∠B + ∠C = 180
45 + ∠B + 45 = 180
90 + ∠B = 180
∴ ∠B = 90
This means that ΔABC is a right triangle.
If ΔABC is a right triangle, then BC is the height of the triangle, because it is the altitude that forms a 90 degree angle.
If ΔABC, then AB is the base of the triangle.
Thus, we need to solve for BC, substitute it into the area formula, and solve for the area.
To find an unknown side length, we use trigonometric functions.
⭐What are trigonometric functions?
ratios of side lengths in respect to an angle in order to find an unknown side length⭐What are the types of trigonometric functions?
sin(θ) = opposite/hypotenusecos(θ) = adjacent/hypotenusetan(θ) = opposite/adjacentTo determine which trigonometric function we use, we need to see the type of side lengths we are given (adjacent, opposite, or hypotenuse).
We are given side length AB, which is adjacent to ∠A.
We want to find side length BC, which is opposite of ∠A.
∠A = 45 degrees.
Therefore, we will use tan(θ).
Substitute the values of the side lengths and angle measure into tan(θ):
\(tan(x) = \frac{opposite}{adjacent}\)
\(tan(45) = \frac{BC}{5\sqrt{2}}\)
Compute using the trigonometric table (i attached it to this response):
\(tan(45) = \frac{BC}{5\sqrt{2}}\)
\(1 = \frac{BC}{5\sqrt{2}}\)
\(5\sqrt{2} = BC\)
∴ BC, the height, = \(5\sqrt{2}\)
Substitute the values of the base and the height into the area formula, and solve for the area:
\(area = \frac{1}{2}(bh)\)
\(area = \frac{1}{2}(5\sqrt{2}*5\sqrt{2})\)
\(area = \frac{1}{2}(50)\)
\(area = 25\)
∴ The area of ΔABC = 25
