A group of friends were working on a student film. They spent all their budget on props and costumes. They spent $693 on props,

sergeinik [125]

Answer:

The total budget is $1260

Step-by-step explanation:

Given

$Props = \$693$

$Costumes = 45\%$

Required

Determine the total budget

Since all budgets was spent on Props and Costumes only.

We have that.

$\%Props + \%Costumes = 100\%$

$\%Props + 45\%= 100\%$

$\%Props= 100\% -45\%$

$\%Props= 55\%$

In other words, 55% was spent on Props

Let the total budget be x, we have:

$55\% * x = \$693$

Make x the subject

$x = \$693/55\%$

$x = \$1260$

Hence, the total budget is $1260

A 90% confidence interval for the average salary of all CEOs in the electronics industry was constructed using the results of a

Stella [2.4K]

Answer:

b) We are 90% confident that the mean salary of all CEOs in the electronics industry falls in the interval $139,048 to $154,144.

Step-by-step explanation:

Confidence interval:

Confidence level of x%

We build from a sample.

Between a and b.

Intepretation: We are x% sure that the population mean is between a and b.

In this question:

90%

45 CEO's

Between ($139,048, $154,144).

So

We are 90% sure that the mean salary of all CEO's falls within this interval.

The correct answer is:

b) We are 90% confident that the mean salary of all CEOs in the electronics industry falls in the interval $139,048 to $154,144.

X, Y and Z form the vertices of a triangle. XY = 12.4m, XZ = 10.4m and YZ = 8.7m. Find the angle ∠ YXZ rounded to 1 DP.

sweet-ann [11.9K]

Answer:

43.8°

Step-by-step explanation:

Applying,

Cosine rule,

From the diagram attached,

x² = y²+z²-2yxcos∅.................... Equation 1

where ∅ = ∠YXZ

Given: x = 8.7 m, y = 10.4 m, z = 12.4 m

Substitute these values into equation 1

8.7² = 10.4²+12.4²-[2×10.4×12.4cos∅]

75.69 = (108.16+153.76)-(257.92cos∅)

75.69 = 261.92-257.92cos∅

collect like terms

257.92cos∅ = 261.92-75.69

257.92cos∅ = 186.23

Divide both sides by the coefficient of cos∅

cos∅ = 186.23/257.92

cos∅ = 0.722

Find the cos⁻¹ of both side.

∅ = cos⁻¹(0.7220)

∅ = 43.78°

∅ = 43.8°
