You pick a card at random. Without putting the first card back, you pick a second card at random. Card numbers are 2, 3, 4, and 5 What is the probability of picking a 2 and then picking a number greater than 3? (Write your answer as a fraction or whole number.)
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

Find the measure of the vertex angle.
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°

The weight of laboratory grasshoppers follows a Normal distribution, with a mean of 90 grams and a standard deviation of 2 grams. What percentage of the grasshoppers weigh between 86 grams and 94 grams?
A. 99.7%
B. 95%
C. 68%
D. 47.5%
E. 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.
What is normal distribution?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)

Manuel wants to earn at least $44 trimming trees. He charges $6 per hour and pays $4 in equipment fees. What are the possible numbers of hours Manuel could trim trees? Use (t) for the number of hours. Write your answer as an inequality solved for (t).
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.
