Answer:

An =4^(n-1)

Step-by-step explanation:

hello :

the sequence is geometric because : (-64)/(-16) = (-16)/(-4)=-4/-1= 4=r

the nth term is :  An =A1 × r^(n-1)

a common ratio is : r  and A1 the first term

in this exercice :   r =4        A1 = 1

An =A1 × r^(n-1)

An =1 × 4^(n-1)=4^(n-1)

Answer:

46.75 dollars

Step-by-step explanation:

If the jeans are on sale for 45% off, then they will cost 55% of the original price (100%-45%=55%).

Therefore, the sale price is:

85×55%

Change % into a decimal

= 85×0.55

= 46.75

Therefore, the sale price of the jeans is 46.75 dollars.

I hope this helps!

The most common measures are mean, median, and mode. MIS. Measure ... For an even amount of data values - Calculate the mean of the two middle numbers. ... store had total sales of $436, $650, $530, $500,$650, $489, and $423 last week. ... would make the store's sales last week appear the most profitable? Explain.

The mean and the median of the data will be $525.43 and $500, respectively.

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.

A retail store had total sales of $436, $650, $530, $500, $650, $489, and $423 last week.

Then the mean of the data will be

Mean = (436 + 650 + 530 + 500 + 650 + 489 + 423) / 7

Mean = $525.43

Arrange the data in ascending order, then we have

$423, $436, $489, $500, $530, $650, $650

Then the median of the data will be

Median = $500

Answer:

12 ft

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle θ = 41.5°

Opposite = 8 ft

Length of handrail =?

We can obtain the length of the handrail by calculating the Hypothenus. This can be obtained as follow:

Angle θ = 41.5°

Opposite = 8 ft

Hypothenus =?

Sine θ = Opposite /Hypothenus

Sine 41.5 = 8 / Hypothenus

0.6626 = 8 / Hypothenus

Cross multiply

0.6626 × Hypothenus = 8

Divide both side by 0.6626

Hypothenus = 8 / 0.6626

Hypothenus = 12 ft

Thus, the Lenght of the handrail is 12 ft

Answer:

answer is b.

Step-by-step explanation: use formula

V=1/3(hπr²)

so using this formula gives us 1275.62897 but rounded off gives us 1,275.63 ft3

ok the diameter is 21 3/4ft i converted it to a decimal, 21.75ft so to get the radius i 21.75ft/2= 10.875ft

ok to continue

V=1/3(hπr²)

V=1/3(3.14*10.875ft)h

V=1/3(118.265625ft)

V=1/3(118.265625 ft)10.3ft

V=1275.62897 which rounded=1,275.63 ft3

Answer:

13 edges

Step-by-step explanation:

Euler's formula for polyhedra states that

F + V - E = 2 ( F is faces, V is vertices and E is edges ) , then

5 + 10 - E = 2

15 - E = 2 ( subtract 2 from both sides )

13 - E = 0 ( add E to both sides )

13 = E

The polyhedron has 13 edges

Answer:

  C)  4

Step-by-step explanation:

We observe that the top segments are in the same 3:4 ratio as the bottom segments. This means they are the same lengths: 3x = 12, 4x = 16. Either of these equations tells us x = 4.

Additional comment

In case you aren't convinced, you can solve this using the secant rule for segments and circles: the product of the lengths to the circle intercepts are the same for both secants.

Answer:

Option A

Step-by-step explanation:

Y is the amount of back pack

The total amount is represented by m

If Y is the cost of back pack purchased by Oliver, then 0.7 Y is the tax applicable on the purchase of back pack

Hence, the remaining cost would be total amount with Oliver minus the cost of back pack and the tax applicable on the purchase of back pack

Remaining cost  = m - (y + 0.07y)

Hence, option A is correct

Answer:

0.9772 = 97.72% probability that the grade of a randomly selected students score is more than 60.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

The average grade for an exam is 74, and the standard deviation is 7.

This means that [tex]\mu = 74, \sigma = 7[/tex]

What is the probability that the grade of a randomly selected students score is more than 60?

This is 1 subtracted by the pvalue of Z when X = 60. So

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

[tex]Z = \frac{60 - 74}{7}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

1 - 0.0228 = 0.9772

0.9772 = 97.72% probability that the grade of a randomly selected students score is more than 60.

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a batter hits a baseball with an initial horizontal speed of 74 mph and an initial rate of climb of 61 mph.

[A] -

The initial speed of the ball when it leaves the bat will be -

v = √(v(h)² + v(c)²)

v = √((74)² + (61)²)

v = 95.9 mph

[B] -

The angle made will be -

Ф = tan⁻¹(61/74) = 39.49°

Therefore -

Step-by-step explanation:

im too tired to explain just trust me

(5) + 2 = 7

2(5) + 3 = 13

13 * 7 = 91

Step-by-step explanation:

Given area = 91m²

length = 2x+3 m

breadth = x +2 m

we know,

Area = length x breadth

91 = (2x+3) x (x+2)

91 = 2x² + 4x + 3x + 6

91 = 2x² + 7x + 6

2x² + 7x - 85 = 0

(2x+17)(x−5)=0

2x+17=0 or x−5=0
