u – v in component form and is  (-8,-6).

We have given that,

Vector u has initial point at (6, 8) and a terminal point at (3, –2).

Vector v has initial point at (–4, –3) and a terminal point at (1, –7).

The component form of a vector is the ordered pair that describes the changes in the x- and y-values.

Given:

Manuel wants to earn at least $44 trimming trees.

He charges $6 per hour and pays $4 in equipment fees.

To find:

The possible numbers of hours Manuel could trim trees.

Solution:

Let t be the numbers of hours Manuel could trim trees.

Earnings of Manuel in one hour = $6

Earnings of Manuel in t hour = $6t

He pays $4 in equipment fees. So, we will subtract this from the income.

[tex]\text{Total earnings}=6t-4[/tex]

Manuel wants to earn at least $44 trimming trees. It means, total earnings must be greater than or equal to 44.

[tex]6t-4\geq 44[/tex]

[tex]6t\geq 44+4[/tex]

[tex]6t\geq 48[/tex]

Divide both sides by 6.

[tex]t\geq \dfrac{48}{6}[/tex]

[tex]t\geq 8[/tex]

Therefore, the required number of hours must be greater than or equal to 8 hours.

Answer:

∠ Y = 34°

Step-by-step explanation:

Since XY = ZY then the triangle is isosceles and the base angles are congruent, thus

∠ X = ∠ Y , that is

6x - 23 = 4x + 9 ( subtract 4x from both sides )

2x - 23 = 9 ( add 23 to both sides )

2x = 32 ( divide both sides by 2 )

x = 16

Thus

∠ Z = 4x + 9 = 4(16) + 9 = 64 + 9 = 73° = ∠ X

Hence

vertex angle Y = 180° - (73 + 73)° = 180° - 146° = 34°

Answer:

95%

Step-by-step explanation:

Do the math it's pretty easy.

When the weight of laboratory grasshoppers follows a normal distribution, with a mean of 90 grams and a standard deviation of 2 grams, 95% of grasshoppers weigh between 86 and 94 grams.

Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Let W be the sample of weight of laboratory grasshoppers.

W follows N(90, 2)

To calculate P(86 < W < 94)

[tex]P ( 86 < W < 94 ) \\\\P ( \frac{86 - 90}{2} < \frac{W - 90}{2} < \frac{94 - 90}{2} )\\\\P(-2 < Z < 2)\\[/tex]

= 95% (approximately)

(using excel function NORM.S.DIST(2,TRUE)-NORM.S.DIST(-2,TRUE))

Answer:

80 miles per hour

Answer:

1/6

Step-by-step explanation:

When trying to calculate the probability of a sequence of events you need to multiply the probability of the first event happening by the probability of the second event happening. There are a total of 4 numbers (2,3,4,5) and only one is a 2. Therefore the probability of the first pick being a 2 is 1/4. Now there are only 3 cards left (3,4,5) and only 2 numbers are greater than 3 so the probability of picking one of these cards is 2/3. Now that we have both of these probabilities we simply multiply them together.

1/4 * 2/3 = 2/12 or 1/6

Therefore, the probability of picking a 2 and then picking a number greater than 3 is 1/6
