We are given:

Diagonal Length of the screen = 18 inches

Length of the screen = 7 inches

Width of the screen = x inches

Finding the width:

In the image, we notice a right-angle triangle

So, we can find x using the Pythagoras theorem

Using the Pythagoras theorem:

18² = 7² + x²

x² = 18² - 7²

x² = 324 - 49

x² = 275

x = 16.6

Hence, the screen is 16.6 inches wide

We are to find the width of the laptop

The width of the laptop is 16.6 inches

Diagonal length of the laptop = 18 inches

Length of the laptop = 7 inches

Width of the laptop = x inches

Using Pythagoras theorem

Diagonal ² = length ² + width ²

18² = 7² + x²

x² = 18² - 7²

x² = 324 - 49

x² = 275

find the square root of both sides

x = √275

x = 16.58

Approximately,

x = 16.6 inches

Answer:

x=3

Step-by-step explanation:

5(2x-3)=15

10x-15=15

10x=30

x=3

Answer:

x=3

Step-by-step explanation:

5(2x -3) = 15

10x-15=15

10x-15+15=15+15

10x=30

To find the x divide 10 to 30 so that is why 30÷10=3.

We want to find a polynomial

f(x) = a x³ + b x² + c x + d

such that the roots of f are x = -3, x = -1, and x = 4, and f(x) takes on a value of -24 when x = -2.

The factor theorem for polynomials tells us that we can factorize f(x) as

a x³ + b x² + c x + d = a (x + 3) (x + 1) (x - 4)

Expand the right side:

(x + 3) (x + 1) (x - 4) = x³ - 13x - 12

So we have

a x³ + b x² + c x + d = a x³ - 13a x - 12a

In order for both sides to be equal, the coefficients of both polynomials on terms of the same degree must be equal. This means

a = a (of course)

b = 0 (there is no x² term on the right)

c = -13a

d = -12a

We also have that f (-2) = -24, which means

f (-2) = a (-2 + 3) (-2 + 1) (-2 - 4)

-24 = 6a

a = -4

which in turn tells us that c = 52 and d = 48.

So we found

f(x) = -4x³ + 52x + 48

Answer:

Greatest Common Factor: 24

Step-by-step explanation:

The greatest common factor is found by multiplying all the factors which appear in both lists: So the GCF of 24 (2x2x2x3) and 48 (2x2x2x2x3) is 2x2x2x3 which is 24.

The greatest common factor of 24 and 48 is 24.

Here, we have,

To find the greatest common factor (GCF) of 24 and 48,

we can use the prime factorization method:

Step 1: Find the prime factorization of each number.

Prime factorization of 24:

24 = 2 * 2 * 2 * 3

Prime factorization of 48:

48 = 2 * 2 * 2 * 2 * 3

Step 2: Identify the common prime factors and their lowest exponents.

Common prime factors: 2 * 2 * 2 * 3

Step 3: Multiply the common prime factors with their lowest exponents.

GCF(24, 48) = 2 * 2 * 2 * 3 = 24

So, the greatest common factor of 24 and 48 is 24.

Answer:

d. Reject the claim that mean is 40 MPG when it is actually 40 MPG.

Step-by-step explanation:

The type 1 error could be said to have been made if the null hypothesis is erroneously rejected.

In the scenario above :

The null hypothesis (H0) : mean = 40

Hence, if the Null hypothesis defined above is rejected when in fact the hypothesis that the mean miles per gallon is actually 40.

On the other hand, the type 2 error occurs when a null which is false is not rejected.

Hence, when a true null is rejected, a type 1 error is committed. Similarly, when a false null isn't rejected, then a type 2 error has been committed.

Answer:

The answer is below

Step-by-step explanation:

a) A linear function shows the relationship between variables. A linear equation is in the form: y = mx + b, where m is the rate of change, b is the value of y when x = 0, y is the dependent variable and x is an independent variable.

Let U represent the number of umbrellas and p the price of the umbrella. At $10 the number of umbrella sold is 18000, it can be represented as (10, 18000) i.e. (p, U)

At $16 the number of umbrella sold is 9000, it can be represented as (16, 9000).

The linear function is determined using:

[tex]U-U_1=\frac{U_2-U_1}{p_2-p_1}(p-p_1)[/tex]

Given (10, 18000) and (16, 9000):

[tex]U-U_1=\frac{U_2-U_1}{p_2-p_1}(p-p_1)\\\\U-18000=\frac{9000-18000}{16-10}(p-10)\\\\U-18000=-1500(p-10)\\\\U-18000=-1500p+15000\\\\U=-1500p+15000+18000\\\\U=-1500p+33000\\\\U(p)=-1500p+33000[/tex]

b) At p = $20, The number of umbrella is:

U(20) = -1500(20)+33000

U(20) = 3000 umbrella

Answer:

Y=21

X=8

Step-by-step explanation:

In the middle there is a right angle

therefore 27 +3y=90

Y will be 21

Then x+27+63+8x+18=180

x=8

Hence 8+27+3(21)+8(8)+18=180

Step-by-step explanation:

27 + 3y = 90

3y = 90 - 27

y = 21

27 + (21×3) + x + 8x + 18 = 180 ( angles on a straight line sum up to 180)

9x + 108 = 180

9x = 180 - 108

9x = 72

x = 72/9

x = 8 degrees
