Solving the equation, it is found that it is classified as conditional.

  • It is conditional if there is a solution for x.
  • It is an identity if both sides are equal.
  • If is a contradiction if there are no solutions for x.

The equation is:

-4 + 3x - 5x = -1 - 10 + x

Solving it:

-4 - 2x = x - 11

3x = 7

x = \frac{7}{3}

Solution for x = \frac{7}{3}, thus conditional.

postnew [5]

Answer:

The claim that he rate of inaccurate orders is equal to​ 10% is supported by statistical evidnece at 5% level

Step-by-step explanation:

Given that in a study of the accuracy of fast food​ drive-through orders, one restaurant had 34 orders that were not accurate among 371 orders observed.

Sample proportion p=0.092\\q=1-p = 0.908\\n = 371

H_0: p =0.10\\H_a: p \neq 0.10

(Two tailed test at 5% significance level)

p difference = 0.092-0.100\\=-0.0084

Std error if H0 is true = \sqrt{\frac{0.1(0.9)}{371} } \\=0.016

Test statistic Z = p diff/std error

=0.539

p value = 0.5899

Since p > 0.05 accept null hypothesis

The claim that he rate of inaccurate orders is equal to​ 10% is supported by statistical evidnece at 5% level

If logM/N=5 and logP/N=7, what can you say about the relationship between M and P?. . A. M=2P. B. P=2M. C. P=100M. D. P=10M
liubo4ka [24]
<span>log (M/N) = log M - log N
 so log M - log N = 5
log (P/N) = log P - log N
so log P - log N = 7
 If you subtract equation 2 from equation 1, you have log M - log P = -2
 That means that log (M/P) = -2 ----> 10^-2 = M/P ---> P = 100M</span>

You have 30 coins in your wallet, all dimes and nickels. If the total of the change in your wallet is $2.60, then how many dimes
lidiya [134]

Answer:

  • 22 dimes
  • 8 nickels

Step-by-step explanation:

If all were dimes, you'd have $3.00. You have $0.40 less. Each dime that is replaced by a nickel subtracts $0.05, so there are $0.40/$0.05 = 8 nickels. That leaves 30-8 = 22 dimes.

You have 22 dimes and 8 nickels in your wallet.

A system of equations is shown below: n = 3m + 7 n − 2m = 1 What is the solution, in the form (m, n), to the system of equations
LiRa [457]
N=3 m+7
n-2 m=1     | -2 m      => n=1+2m

n=3 <span>m+7
</span><span>n=1+2 m
</span>
n=n

3m+7=1+2m       |-7 and -2m
m = -6

n=1+2m 
n=1+2*(-6)
n=-11

(-6,-11)
