Answer:

D

Step-by-step explanation:

(z + 6)(2z² + 3z + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

z(2z² + 3z + 5) + 6(2z² + 3z + 5) ← distribute parenthesis

= 2z³ + 3z² + 5z + 12z² + 18z + 30 ← collect like terms

= 2z³ + 15z² + 23z + 30

  x = 0 or 1/2

Step-by-step explanation:

Solving an exponential equation of this nature with different bases and coefficients is always a bit of an ad hoc affair. Here, we can divide by the right side expression and make a substitution that turns it into a quadratic.

Using the t-distribution, as we have the standard deviation for the sample, the 95% confidence interval is (71.63, 84.36).

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 4 - 1 = 3 df, is t = 3.1824.

The parameters are given as follows:

[tex]\overline{x} = 78, s = 10, n = 4[/tex]

Hence, the bounds of the interval are given by:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 78 - 3.1824\frac{10}{\sqrt{4}} = 71.63[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 78 + 3.1824\frac{10}{\sqrt{4}} = 84.36[/tex]

The 95% confidence interval is (71.63, 84.36).

The probability of drawing an even number is 1/2.

The probability of drawing a card that can be divided by 5 is 1/5.

The probability of drawing a card that can be divided by 10 is 1/10.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

a.

There are 20 even numbers between 1 and 40.

The probability of drawing an even number.

= 20/40

= 1/2

b.

There are 8 numbers between 1 and 40 that can be divided by 5 (5, 10, 15, 20, 25, 30, 35, and 40).

The probability of drawing a card that can be divided by 5.

= 8/40

= 1/5

c.

There are 4 numbers between 1 and 40 that can be divided by 10 (10, 20, 30, and 40).

The probability of drawing a card that can be divided by 10.

= 4/40

= 1/10

Thus,

The probability of drawing an even number is 1/2.

The probability of drawing a card that can be divided by 5 is 1/5.

The probability of drawing a card that can be divided by 10 is 1/10.

Answer:

Q=91, S = 153

Step-by-step explanation:

QR and TS are parallel (see the arrows in the middle?). Means that angles T and Q add up to 180 - they are conjugate angles. Thus Q has to be 89 (since 89+91=180).
Same difference for R and S: they add up to 180 and since one is 27, the other has to be 153.

Volume of the box = 5.2 × 9.6 × 6

= 299.52 ≈ 300 cm³ (approx)

The values of the x when the square root is taken on both sides are negative 4 and negative 14.

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

The equation is given below.

(x + 9)² = 25

Taking square root on both sides, then we have

(x + 9) = ±5

When the positive sign is considered, then we have

x + 9 = 5

     x = -4

When the negative sign is considered, then we have

x + 9 = -5

     x = -14

The volume of air needed is equal to the volume of the sphere, which is 7,234.56 cm^3.

The volume of air that we need is equal to the volume of the basketball.

Remember that for a sphere of radius R, the volume is:

V = (4/3)*3.14*R^3

In this case, the radius is 12cm, replacing that we get:

V = (4/3)*3.14*(12cm)^3 = 7,234.56 cm^3

Then, to fully inflate the ball, we need  7,234.56 cm^3 of air.
