Answer:

for number 23 the answer is 58 degrees

for number 24 the answer is 23 degrees

Step-by-step explanation:

23)

we know that every hour it decreases by 6 degrees, so all we have to do is decrease by 12 to make up for the remaining two hours. So the answer is 58

24) You substitute C for -5 so 9/5 times -5 which equals -9. Then, -9+32=23 degrees.

An automobile manufacturer has discovered that 20% of all the transmissions it installed in a particular style of truck are defe

Hatshy [7]

Answer:

0.148 = 14.8% probability that they will need to order at least one more new transmission

Step-by-step explanation:

For each transmission, there are only two possible outcomes. Either it is defective after a year of use, or it is not. The probability of a transmission being defective is independent of any other transmission. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

20% of all the transmissions it installed in a particular style of truck are defective after a year of use.

This means that $p = 0.2$

Sold seven trucks:

This means that $n = 7$

It has two of the new transmissions in stock. What is the probability that they will need to order at least one more new transmission?

This is the probability that at least 3 are defective, that is:

$P(X \geq 3) = 1 - P(X < 3)$

In which

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{7,0}.(0.2)^{0}.(0.8)^{7} = 0.2097$

$P(X = 1) = C_{7,1}.(0.2)^{1}.(0.8)^{6} = 0.3670$

$P(X = 2) = C_{7,2}.(0.2)^{2}.(0.8)^{5} = 0.2753$

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.2097 + 0.3670 + 0.2753 = 0.852$

$P(X \geq 3) = 1 - P(X < 3) = 1 - 0.852 = 0.148$

0.148 = 14.8% probability that they will need to order at least one more new transmission

What is the value of the expression

PtichkaEL [24]

Answer:

Step-by-step explanation:

Multiplying bases with exponents means you have to multiply the base and add the exponent. So:

(10⁴)(5²) = 50⁶

(10³)(5³) = 50⁶

Now the equation is (50⁶/50⁶)³

Anything divided by itself will be one, so the number inside the parentheses is 1.

Now the equation is 1³, and 1x1x1 is 1.

Explain the steps to put 36/10 as a decimal

schepotkina [342]

36 divided by 10

10 goes into 36 at least 3 times, 30

Then there is the 6 left over that turns in to 6 out of 10, .6

So 3.6 is your answer

kipiarov [429]

Answer:

D. AG ≅ NP

Step-by-step explanation:

Given that quadrilateral ACEG is congruent to quadrilateral NMRP, this means that all the corresponding sides of both quadrilaterals are congruent to each other.

Considering the arrangement of the letters we can reduce the following:

AC corresponds to NM, therefore AC ≅ NM.

CE corresponds to MR, therefore, CE ≅ MR.

AG corresponds to NP, therefore AG ≅ NP.

EG corresponds to RP, therefore, EG ≅ RP.

The only statement that is true among the options given is:

AG ≅ NP

If m = 8, what is 4m + 2m?<br><br> Hint: "4m" means "4 TIMES m" and "2m" means "2 TIMES m"

aleksandr82 [10.1K]

Answer:

Step-by-step explanation:

4m means 4xm, and 2m means 2xm

Now, if m = 8, 4m means 4x8, and 2m means 2x8. (Technically, substituting the number in place of the variable m)

4x8 = 32

2x8 = 16

So the equation now is 32+16

Do the math and you get 48
